3D Printer Research and Development
The OSE printer is called D3D - for Distributive Enterprise 3D Printer. For Current Work see 3D Printer Genealogy.
Overview
3D Printers are a subset of CNC machines: they use stepper motors to move along X, Y, and Z axes according to gCode - essentially a text file with thousands of lines of coordinates and special commands (such as "return to origin" or "set nozzle temperature"). As motors on each axis moves the nozzle through 3D space, an additional motor feeds plastic filament through a heating element, very much like an automatic hot glue gun.
The software that turns a 3D model (such as an .stl or .obj) into instructions telling the printer how to move is called a "slicer" - it slices a model into layers that will stack up to make the finished object.
Many options exist for controlling the printer with your computer - nowadays several "slicers" can also connect to the printer directly, streamlining the printing process.. As a central backbone of Digital Fabrication, the end goal of 3D printers is to be able to print anything.

Printing Process
(just adding a note here, please move where it fit better) To improve movement speed/accuracy of the printer head i was thought about a dual motor set (each axis) coupled with a differential gear-set so would be possible to reduce or multiply output turns with a digital controller that regulate the ratio of the two motors rotation. (not sure how to implement this and not sure it may be so effective, i just believe this may open for bigger volume printers (3m cube hypothesis). (adexmont 18/nov/2018)

Overview
The Aluminum Extractor extracts raw aluminum from alumina common clay (alumina silicate).
Detail
Using a closed-loop cycle involving hydroflouric acid and a large amount of electricity, it is possible to extract raw aluminum directly from clay deposits. This is in contrast to the typical aluminum extraction technique from strategic bauxite mineral reserves.
There is posibility also to produce bauxite from very common feldspar mineral (sand) and carbon dioxide. This is natural process that produce clays, but it is posible to speed up usable level with increasing carbon dioxide partial pressure. Easy source for carbon dioxide are biogas reactors. Biogas cleaning produce large amounts pressurized carbon dioxide water solution. It is even posible to directly feed pressurized biogas through feldspar sand column and combine both process.
Alumium electrolyze process should be combined to localized power grid and its power consume should be tied to grid frequency after 50.5Hz or 60.5hz it should start itself and come full power until 51.0Hz or 61Hz so alumium making can be used to dump excess energy. Very useful combined with windpower.

Overview
The Backhoe is a piece of excavating equipment used for digging holes and trenches.
Versions
Backhoe 4
No real plans for Backhoe 4 as of Oct 2013. That's just a place to record ideas for a future version.
Backhoe 3
Under active development as of Oct 2013
Backhoe 2
Plans and photos from the 6 in 60 campaign. See Cory Shenk Log for iterations of the design.
- This is the most recent version of the backhoe that I have upon the end of 6 in 60: File:Backhoe deep dig.skp
- We were never able to completely build it but we did complete sections and components. Check Leandra's Log and Luca's Log for any other information. We spent a decent chunk of time working on these together.
Bucket
- Parts for the body of the bucket. I used three pieces that were 4 inches wide as you can see in the photo. Two should be replaced with an 8 inch wide piece of the same length. It reduces the amount of welding required and adds strength to the bucket.
- You can see two pieces have already been welded. This should be cut out of one piece of steel.
- I allowed myself extra room on the pieces that I cut for the sides of the bucket. This allowed some wiggle room when assembling the entire thing.
- Step by Step in Photos
.JPG)
- The connection points should be revisited for better attachment to the stick. See Stick Design.
- There was often physical conflict where points attached that had square corners (in the case of the bucket and in other areas, usually cylinders). It might be a good practice to simply always notch them off or round the corners with the torch, or fabricate a rounded blade for the iron worker.
- The teeth of the bucket are bolted on so that they can easily be removed. This seems unnecessary, especially in a final version.
- I cannot determine how the shape of the bucket will affect its performance. This will need to looked into upon completion.
Stick
- Although we never reached the point of assembling the entire Boom and Stick to the Pivot, my guess (based off of many experiences in that workshop) is that there would have been conflict with the bolts and cylinders within the range of motion.
- To limit the amount of times that this occurs it would be beneficial to draw very exact models of bolts, washers, nuts, etc. Included with these should also be cylinders of various sizes, especially the sizes that would be used frequently.
- One variable that would be tricky account for is the way that beams and plates fit together.
- Is it possible to create warehouse pieces that include variables like these?
- 1
- 2
- 3
- As you can see in photos 1, 2, and 3, the triangular design that allows greater range of motion for the bucket had to be made wide to clear the bolts. This resulted in a lot of side to side movement of these pieces which is not ideal, especially under load.
- One possible solution would be to weld the two beams instead of bolting. This would allow the triangular component to rotate along the side of the stick, reducing the play.
- 4
- If bolts are still used then the method of connecting the pieces needs to be addressed. We used threaded rod because we were in a rush and did not have the proper materials on hand. Threaded rod is decidedly weaker than a smooth rod. A tractor pin, or its equivalent, would be better, but it is still a great distance to span.
- 5
- This design employs 4 points of rotation. I was attempting to mimic the designs that I found in most commercial backhoes.
- 6
- 7
- Here are some photos that I referenced from a quick Google search:
Pivot
Cylinder - [5]
- The greatest difficulty with the pivot (and every other component we tried to build) was that the holes did not line up which made assembly difficult. The pivot had many areas that required bolts to pass through along with two three inch pins. This exacerbated the problem.
- We found that the best way to assemble was to build the pivot plates AROUND the pin and then bolt the plates to the corresponding tubing.
- The collars cut for the pivot plate were slightly different in width. This caused an irregularity in plate width once they were welded in place.
- The greatest challenge that we had with the pivot was coming up with a design to make the pivot move from side to side. Commercial backhoes have a cylinder that runs in between the top and bottom of the pivot and connects to a "C" shaped piece. Due to lack of time we were not able to come up with anything that would mimic this in design or functionality.
For the Future
- make sure the holes align
- build around the pin
- streamline the pivot (it is very heavy)
- Design with side to side motion in mind
Backhoe 1
Main page for the Backhoe 1.
Details
They are typically mounted on the back of a tractor or front loader, this one is mounted on a LifeTrac. It consists of a digging bucket on the end of a two-part articulated arm. The section of the arm closest to the vehicle is known as the boom, and the section which carries the bucket is known as the dipper or dipperstick (the terms "boom" and "dipper" having been used previously on steam shovels). The boom is attached to the vehicle through a pivot known as the kingpost, which allows the arm to slew left and right, usually through a total of around 200 degrees. Modern backhoes are powered by hydraulics.
The backhoe is one of the most basic dirt working tools and is a common attachment to many small tractor and skid-steer vehicles. It can be used for digging trenches for foundations, digging up material to make compressed earth blocks, digging waste pits, and many other common building/farming tasks. Furthermore, by attaching a chain to the bucket, the backhoe can be used to lift and transport heavy loads such as engine blocks, battery packs, long pieces of pipe, etc.
Commercially manufactured backhoes vary greatly in their size and capabilities and therefore vary significantly in price. A quick google search seems to indicate that relatively small, simple devices like the one we are considering range from 2 to 4 thousand dollars with more sophisticated attachments approaching 10 thousand dollars.

Overview
The Bioplastic Extruder enables plastics production.
"Plastics extrusion is a high volume manufacturing process in which raw plastic material is melted and formed into a continuous profile. Extrusion produces items such as pipe/tubing, weather stripping, fence, deck railing, window frames, adhesive tape and wire insulation." - (wikipedia)
Detailed Description
We aim to develop computer-controlled tools that can make plastic parts of any shape. 'Extrusion' means squeezing out a long shape; extruding a circle gives you a cylinder. Extruded plastic forms include sheets, tubes, and others. Greenhouse glazing made of polycarbonate, or UV-stabilized polyethylene, water pipes for plumbing and irrigation, plastic shapes and sheets are all doable with slight modifications of a basic extruder. The key may be a ram extruder (simple design) with inductive heating, to which various dies are adapted for profiles (extrusion), or molds for shapes (injection molding), or blowers and molds (blow molding).
With these tools, cheap feedstocks can produce very expensive products. For instance, polyethylene resin costs less than 15 cents/lb (at a density of 50 lb/cubic ft (800g/l)). When extruded into panes of Solexx glass, the end product costs $1/square foot ($10.76/m2). This makes the end product about 20 times more valuable than the feedstock. If an extruder is available - combined with the know-how - then localized production of such glazing could probably yield cost predictions of something marginally higher than material costs, under the DIY-flexible enterprise scenario.
The challenge is procuring the know-how for extruder fabrication and material extrusion. The material costs are expected to be around $5k for the machine - structure, hydraulic ram, inductive heating, and die.
Bioplastics
Bioplastics are the perfect addition to an integrated farm and forestry operation. An effective open-source method of producing bioplastics will allow communities to be self-sufficient in the raw materials for many modern comforts. Bioplastics promise to replace the many useful products we currently extract from oil. Combined with plastic extrusion and molding machines such as RepRap, bioplastics enable a local manufacturing process that starts with food waste or soil and creates computer and phone casings, car and machine parts, toys and tools, screws and sculptures.

Proof of Concept of MicroTrac Scalability - LifeTrac 7
The MicroTrac is overbuilt to 8000 lb of drive torque plus the ability to carry an extra 6000 lb of weight outside of its existing 2000 lb weight. With the structural Power Cube as the basis for other attachments, the MicroTrac can be scaled in size to build bulldozers by stacking 3 MictroTracs together for 24,000 lb of torque at the tracks. See initial testing of weight handling capacity, where the MicroTrac carries 6000 of dead weight, and is shown running in idle:

Overview
The Bulldozer is a high-traction, earth-moving machine indispensible to building ponds, berms, or other earth-moving tasks such as building roads or clearing land. See Bulldozer Specification
Details
Most often, bulldozers are large and powerful tracked heavy equipment. The tracks give them excellent ground hold and mobility through very rough terrain. Wide tracks help distribute the bulldozer's weight over a large area (decreasing pressure), thus preventing it from sinking in sandy or muddy ground. Extra wide tracks are known as 'swamp tracks'. Bulldozers have excellent ground hold and a torque divider designed to convert the engine's power into improved dragging ability. The Caterpillar D9, for example, can easily tow tanks that weigh more than 70 tons. Because of these attributes, bulldozers are used to clear areas of obstacles, shrubbery, burnt vehicles, and remains of structures.
The GVCS variant is being pursued as a Tractor bladed retrofit with lower torque, and additional weight

Joe Justice and Team Wikispeed are awesome and we're planning a formal partnership!
The instructions for copying Team Wikispeed's SGT01 car design are currently being built. You can find them here Wikispeed_SGT01
OSVehicle Tabby
The OSVehicle Tabby's chassis, suspension, ... can be ordered from their website (see also here). The vehicle can then be custom made by the person that ordered the parts.
Custom mini moke
A custom mini moke can be created for the purpose of creating a community of green mechanics which also organise races (on regular karting tracks). The mini moke design will form the "glue" to create this community due to the fact that unlike with regular karts, no trailer is needed to transport the racing vehicle (instead, the mini car can be driven itself to the track, and even also prove useful for day to day activities, meaning it isn't just an expense done for hobby purposes). The design would hence make the step towards engaging in this hobby smaller, and help convince more people into doing it.
Team Vélocar
Vélocar joined the OSE movement. Vélocar is now the official OSE microcar
Overview
The OS Car will be a lightweight and aerodynamic two passenger long range car that will be fueled with ethanol biodiesel. The current plan is for the car to have a reverse trike configuration: two front wheels and one rear wheel which is the only driven wheel. The two main benefits of the reverse trike design are lower cost and weight due to one less wheel, and lower wind drag due to the rain drop shape of the body. The construction of the car will be a steel space frame covered with non-structural polymer or composite panels. The proposed powertrain is a hybrid hydraulic system which includes a single cylinder engine that runs a hydraulic pump which directly powers a hydraulic wheel motor used to drive the car and which compresses a gas in an accumulator to store energy. Gas in the accumulator will also be compressed via regenerative braking when the hydraulic motor is run in reverse to slow the car down. Cost control and quick development will be maintained by using donor vehicle parts and off-the-shelf parts. Components that cannot be easily manufactured such as brake calipers, steering knuckles, and rims will be sourced from a donor vehicle and components such as instruments, wiring, and hydraulic components will be off-the-shelf components.
As the car design matures, some components from donor vehicles and off-the-shelf components can be replaced by scratch-built open source components. If desired, forks can be spawned from the original project for variants such a four or five passenger car, or perhaps a car with a hybrid electric powertrain.

Overview
The Liberator is OSE's automatic, high throughput Compressed Earth Brick Press. It is named The Liberator because it is intended to free people from the single highest cost of living - housing. See Cost of Living.
The CEB is at product release status and is being actively manufactured at Factor e Farm. The presses was used heavily as a part of the Factor e Farm Infrastructure Buildout 2011. Builds using the OSE CEB ress continued with the Microhouse 1, Microhouse 2, Microhouse 3, and MicroHouse 4 built in 2014 - [7]. We have also built a utility room brick floor and an 8' wall section out of CEBs in the 2016 build of the Seed Eco-Home.
In 2020, we did a CEB Microhouse Build in Belize.
The bill of materials cost of the current, fully-automated machine is about $5000 US. See CEB Press#BOM.
The machine can also be made as a manually-controlled version with hydraulic valves. Other options are:
- small or large hopper
- with or without hopper shaker
- automatic controller at 6-10 bricks per minute, depending on power unit
We are currently selling the full machine without power unit for $10k FOB Kansas City, lead time 2 months. Email info at opensourceecology dot org.
- Price is FOB Kansas City, Missouri, USA, for a fully assembled machine, with quick couplers, ready to be plugged in to a power source. Price for other packing/crating options is extra.
- Delivery time: machines are produced during scheduled production runs, with 8 weeks lead time from submission of payment.
- Buyer is encouaraged to attend the build event - to learn how the machine is designed, built, and therefore, to learn about repair and modification. Basic instruction on using FreeCAD will be provided for viewing the CAD file. An operating and maintenance manual will be provided to the client. The buyer is encouraged to brind additional people to the build event to learn about the machine.
A tractor loader is used to provide approximately 2 cubic yards of soil per hour at at 6 block per minute pressing rate. A tractor loader is needed to keep up with the machine throughput. Approximately 3 people are required to keep up with the machine for stacking the block upon pallets. Approximately 30 people would be required to load the machine manually with shovels and buckets if no tractor loader were available. At the minimum, 4 people (1 tractor operator, 3 stackers) are required to produce palletized block on an all-day basis.
Specifications of the Standard Model
- Block is plain block, not interlocking. Please see discussion on Interlocking_bricks
- Version 17.08 is our most current model. See CEB Press Genealogy for past versions.
- Open source hardware, controller, and software (CC-BY-SA 4.0, GPLv3)
- Controller is fully automated for hands-off operation
- Does NOT come with a power source - it is powered by a hydraulic power source, such as by our Power Cube or a tractor hydraulic take-off.
- Full size bricks are 4"x6"x12", plain flat-faced bricks
- Brick height is adjustable from 2"-4"
- Brick dimensional variations: +/- 1/16". This assumes uniform soil. Soil uniformity will determine height uniformity of brick.
- The standard model guarantees 6 full-sized bricks per minute at 12.5 gallon per minute hydraulic flow. See Brick Pressing Calculations. Brick pressing rate will increase with a higher hydraulic flow, up to the maximum rated flow of the hydraulic solenoid. Hydraulic solenoid valve is rated for a maximum of 10 gpm fluid flow at 3000PSI.
- Cost of production for actual block ranges from 5 cents to 40 cents per block - depending on amount of cement used for stabilization (0-10%) and cost of labor (free to $25/hr). See Cost_of_CEB_Block
- Fuel consumption with Power Cube running at 12.5 gpm fluid flow - about 1 gallon per hour
- System hydraulic pressure - 2400 psi
- Comes with hydraulic quick couplers ready to be connected to a power source
- Weight - 1700 lb
- Moving: brick press is moved with forks. Footprint (with legs in the inner position) allows machine to be placed in the bed of a 3/4 ton pickup. It has adjustable legs for uneven terrain. Machine can be moved around on a trailer (not included)
- Material cost: $3000-$6500 depending on suppliers; manual machine (without hydraulic solenoid, machine costs $1000 less in materials. Production cost for a full kit: US$5000 above the bill of materials/supplies/consumables cost, paid by the buyer. Production currently occurs in Extreme Manufacturing Workshops - where the buyer is invited to the build so they understand how the machine is built - and is part of the buyer's Lifetime DIY Warranty. This warranty means that the user can maintain the machine for decades because they know how the machine is built, how it works, and how to source parts for the machine from local and online sources. This means that this is not a consumer machine, but a prosumer machine.
- 3'x6' grate for loading the machine with a tractor. Includes soil deflectors
Additional Power
The machine can be used to produce up to 10 blocks per minute with a larger power source. A larger secondary hydraulic cylinder must be used in that case. See CEB Press Log for developments.

Details
The CEB Press takes earth/dirt/soil and compresses it tightly to make solid blocks useful for building. Compressed earth blocks have many advantages as a building material: by making the building materials from the readily available dirt on the building site, they eliminate the need to transport bricks from elsewhere, reducing financial cost and environmental impact. Compressed earth blocks are very strong and insulate well against both heat and sound, making for very energy-efficient building (especially combined with the energy savings from not needing to transport them from offsite). Best of all, the material they use is already on-site and does not need to be purchased -- quite literally, dirt-cheap! See the wiki page on Compressed Earth Blocks and the CEB category for more details on building using CEBs.
The Liberator has been fully designed and tested by the Open Source Ecology team. Because the Liberator is an open source technology, you can freely download instructions to build your own from materials you can obtain yourself, or contact opensourceecology[at]gmail[dot]com to buy a kit or a finished machine.
Building a machine yourself might seem intimidating, but every step of the process is fully documented and the OSE community is available on our discussion forums if you need help, advice, or a little hand-holding.
Using the CEB Press, two people can build a 6 foot high (1.83m) round wall, 20 feet (6.1m) in diameter, 1 foot (30cm) thick, in one 8 hour day, though construction time will vary somewhat depending on preparation time, what equipment is available (tractor to prepare the ground and move the blocks where they need to go), the quality of the soil, and other factors. The bigger the block size, the faster a wall can be erected, but at the cost of heavier blocks that are more of a strain to work with. Blocks from The Liberator average 25 pounds (11.3kg).

Overview
A Cement Mixer (also commonly named a concrete mixer) is a device that homogeneously combines cement, aggregate such as sand or gravel, and water to form concrete. [1]
Detailed Description
A concrete mixer (also commonly called a cement mixer) is a device used to automate the preparation of cement by mixing it with other aggregates such as sand or gravel and water to form concrete. A typical concrete mixer uses a revolving drum in which the components are automatically mixed. The resulting mix is used as on of the most important elements on construction.
Concrete is used more than any other man-made material in the world. As a part of the GVCS, it unlocks a range of building techniques and methods, depending on characteristics of the environment and type of structure to be built.

- D3D circuit mill - https://mi_shell.gitlab.io/models_online/ose_webgl/d3d_circuit_mill.html
Genealogy
- The CNC circuit mill took another turn in 2019 with the Open Source Microfactory STEAM Camp, where we built the D3D Universal 3D printer with a hole-drilling capacity for circuit boards.
- D3D CNC Circuit Mill - built in 2018 with the Universal Axis.
- We also built HydraFabber in 2014 - which used a low cost spindle. See John Log for pictures of the mill. This is prior to the Universal Axis, which was introduced in 2016. The spindle was built and run, but we did not mill any boards.
- Yoonseo Kang built a circuit mill while at OSE in 2012. See Yoonseo Log - as a power user, Yoonseo developed a lot of useful proofs of concept, such as the Cold Saw and Tooling Plate, among others. Specifically - v1 was built, and v2 was not. These were pre-Universal Axis.

Design Notes
Note on CAD Procedure and Organization:
- Draw a frame piece, and create a complete frame made of 6 of these pieces.
- Save file: File:D3D 13" Frame.fcstd
- Begin the design by downloading the X axis - File:D3D 16 Sub-assembly X Axis.fcstd
- Correct the length of the axis to 11" length (for 13" frame - 1" shorter on each side to accommodate mounting on the Y axes). Rotate the axis such that the orientation - when looking according to the Viewing Direction and XYZ axis orientation of Slide 1 in Working Document - is that the motor is on the left side of the axis (note that the orientation shown in First Slide in the Working Document has the motor on the right hand side, which is not correct).
- Save the file as File:D3D Circuit Mill X Axis.fcstd once the length is 11" and orientation is correct. This will be the file you can use later for the x axis (2 of them) to merge into the final assembly - with the second x axis being a mirror image.
- Now create the Y axis according to the orientation convention of the First Slide in the Working Document. This axis should be 13" long.
- Save the y axis file as File:D3D Circuit Mill Y Axis.fcstd.
- Now create the Z axis as in the working document. This axis can be 8" long - as we don't need a lot of z travel.
- Save the Z axis file as File:D3D Circuit Mill Z Axis.fcstd.

Overview
The CNC Torch Table (aka RepTab) is an enabling machine for any workshop. This machine enables creation of custom parts for fabrication or replacement of broken components. The CNC Torch/Plasma Table development is rebooting and building on some of the later versions, but starting with the replication of Koruza's Good Enough CNC Plasma Table. One the integrated designs is to go towards gas versus plasma, because of the dependencies of a plasma cutter and other devices that have not been fully open source. As well as the availability of gas production being a valuable option. The Version 3 iteration expects to build, source, and improve designs toward a 100% open source project and parts. The power supply, height controller, torch, and plasma cutter are items needing to be developed. In progress, the need for on-demand materials and supplies can be met with a functional and accurate CNC Torch/Plasma Table that will reduce manufacturing time and increase capacity. The Koruza Project does not a have table, therefore, building on previous versions maybe a possibility.
2019 Update
- Working on CNC Torch Table Height Controller
2016 Update
During the course of 2014/2015 workshops of metal fabrication, the CNC Torch Table/Plasma Table is essential for future builds. The MicroTractor and the World's First Open Source Bulldozer can be built with general metal working toolings, however, the CNC Torch Table is a major manufacturing component of the GCVS. Tom Griffing and Jonathan Kocurek find it a useful effort to focus on the CNC Torch Table for PowerCube replications and parts manufacturing. Marcin's introduction with the Koruza project is a feasible option, however, Marcin's concerns are that some propriety parts exists that will need to be open source and developed. Such as the height controller and power supply. Tentative plans and efforts to grow the CNC Torch/Plasma Table Team are forming for 2016.
2014 Team Goals
Current team goals as of June 5 2014 for the end of June 2014.
- Have the torch cutting steel, up to 1" thick, to a tolerance of 1/16" over 10 inches on all dimensions, and within 1/16 of a straight line re the waviness of the line. It is ok if it takes some manual intervention, or hand holding.
- The machine should be reasonably durable and not finicky or prone to breakage, or absurdly high wear and tear. For example, the wiring is currently prone to breakage. Also the arduino on the z control would probably stop working pretty fast from the stuff splattering on it.
This entails meeting milestone 1 in the torch table prototype 2 requirements document (see dev board through dozuki, overall module, requirements document).
- for the short term, make sure the documentation is at the point that someone can easily step in to Anthony's role in getting things working, and to operate the table for cutting.
- record why we made the system the way we have so far, rather than some other way. This is important to avoid the need to go over the same ground too many times.
2016 Team Goals
- Using 3D Printer Construction Set instance for xyz drive.
- Off-shelf height controller tested, then replaced with open source version
- Open source version - done by a design challenge, such as heroX or simple crowd platform

Overview
The Dairy Milker yields milk and dairy products from dairy cows.
The pulsator can use Solenoid Driver
Detailed Description
The dairy milker is comprised of 4 teatcups that attach onto the teats of the dairy cow. These teatcups connect via short milk tubes and short pulsation tubes to a claw (connection component that links the teatcups to the rest of the dairy milker). The claw is connected via a long milk tube and a long pulsation tube to the milkline (collection bucket), from which the collected milk is transported via airflow and pump to a bulk tank (central storage vat). The dairy milker yields milk from the teats of a cow by applying a continuous vacuum, thereby creating a pressure difference across the teat canal. Because the vacuum causes teat tissue congestion (problematic accumulation of blood and other fluids), air is pulsated to the teatcup liners at pre-determined intervals to ease tissue congestion.
Solution Statement
The agricultural pathway for dairy products necessitate the production of milk, for which the dairy milker provides an automated means to do so.
Product Ecology

Creates
The dairy milker fulfills the role of producing milk from cows through automation.
Components
The major components of the dairy milker include:
- Claw - the intermediary part that connects the short milk and pulsation tubes from the teatcups to the long milk and pulsation tubes going to the collection bucket.
- Teatcups - the direct contact parts that gently clasp onto the teats of a dairy cow so that the applied vacuum yields milk.
- Collection Bucket - The minor receiver of extracted milk that connects to the bulk tank.
- Bulk Tank - The major receiver of extracted milk that can connect to multiple collection buckets.
- Pump and Airflow Circuit - the set of parts that create a pressure difference between the collection bucket and the bulk tank, thereby channelling extracted milk from the collection bucket to the bulk tank.
- Vacuum and Pulsation Circuit - the set of parts that produce the vacuum and air pulsation intervals for milk extraction and teat tissue relief, respectively.
Status
The Dairy Milker is currently in the research phase.

Overview
A drill press (also known as pedestal drill, pillar drill, or bench drill) is a fixed style of drill that may be mounted on a stand or bolted to the floor or workbench. A drill press consists of a base, column (or pillar), table, spindle (or quill), and drill head, usually driven by an induction motor. The head has a set of handles (usually 3) radiating from a central hub that, when turned, move the spindle and chuck vertically, parallel to the axis of the column. The table can be adjusted vertically and is generally moved by a rack and pinion; however, some older models rely on the operator to lift and reclamp the table in position. The table may also be offset from the spindle's axis and in some cases rotated to a position perpendicular to the column.
Details
Status
The Drill Press is currently in the prototype phase of design.

Overview
The Electric Motor serves the function of converting electrical energy into mechanical energy and vice-versa.
Detailed Description
Most electric motors operate through the interaction of magnetic fields and current-carrying conductors to generate force. The reverse process, producing electrical energy from mechanical energy, is done by generators such as an alternator or a dynamo; some electric motors can also be used as generators.
The ideal GVCS motor is one that meets OSE Spec for appropriate scale and ease of fabrication.
While many heavy-duty GVCS technologies are powered by Hydraulic Motors, many of the smaller, more precision actuation is left to Electrical Motors.

Overview
The Gasifier Burner converts biomass fuel into power and useful chemicals.
See Gasifier Development Template for 2015 Development.
Details
This is achieved by reacting the material at high temperatures (>700°C), without combustion, with a controlled amount of oxygen and/or steam, breaking down the biomass into carbon monoxide, hydrogen, carbon dioxide and methane. The resulting gas mixture is a fuel called syngas. If Air is used in place of oxygen the gas also contains inert nitrogen and is called producer gas.

Overview
A hay cutter is a device that cuts grass, hay, straw, or other light biomass. It is part of haying equipment, haybines, silage equipment, mowers, and agricultural combines.
This should really be called a mower. More specifically, a reciprocating mower, sickle mower, or finger-bar mower. A "hay cutter" can be mistaken for something more like a wood chipper that chews up biomass and spits it out a chute.
Details
A cutter has a number of moving parts and is subject to failure. Open source, modular hay cutters solve the need for easy self-maintenance and adaptation to many devices, from combines to balers, reducing infrastructure costs. The goal is a machine that fully meets OSE Spec

Main > Digital Fabrication > RepLab Tools > Induction furnace
Overview
An induction furnace is an electrical furnace in which the heat is applied by induction heating of metal.
Requirements
- Meets OSE Specifications
- Modular in power units of 5 or 10 kW
- Microcontroller-driven - ideally an Arduino brain with power elements
Details
The advantage of the induction furnace is a clean, energy-efficient and well-controllable melting process compared to most other means of metal melting. Most modern foundries use this type of furnace and now also more iron foundries are replacing cupolas with induction furnaces to melt cast iron, as the former emit lots of dust and other pollutants. Induction furnace capacities range from less than one kilogram to one hundred tonnes capacity and are used to melt iron and steel, copper, aluminium and precious metals. Since no arc or combustion is used, the temperature of the material is no higher than required to melt it; this can prevent loss of valuable alloying elements.[1] The one major drawback to induction furnace usage in a foundry is the lack of refining capacity; charge materials must be clean of oxidation products and of a known composition and some alloying elements may be lost due to oxidation (and must be re-added to the melt).
Operating frequencies range from utility frequency (50 or 60 Hz) to 400 kHz or higher, usually depending on the material being melted, the capacity (volume) of the furnace and the melting speed required. Generally, the smaller the volume of the melts, the higher the frequency of the furnace used; this is due to the skin depth which is a measure of the distance an alternating current can penetrate beneath the surface of a conductor. For the same conductivity, the higher frequencies have a shallow skin depth - that is less penetration into the melt. Lower frequencies can generate stirring or turbulence in the metal. A preheated, 1-tonne furnace melting iron can melt cold charge to tapping readiness within an hour. Power supplies range from 10 kW to 15 MW, with melt sizes of 20 kg to 30 tonne of metal respectively.
An operating induction furnace usually emits a hum or whine (due to magnetostriction), the pitch of which can be used by operators to identify whether the furnace is operating correctly or at what power level.

Overview
The industrial robot is an automated machine that perform a wide variety of functions, (including welding, assembly, and CAM, etc...), all depending on which tools its hand is equipped with.
This is the kind of thing you can do with a top-of-the-line industrial robot.
Detailed Description
The industrial robot is a rotating multi-axis machine that can hold various modules (called end-effectors) for performing different tasks such as welding and cutting. These tasks can be done in repetition (through proper "teaching") and with precision (based on the robot's repeatability, which is a measure of how far the robot deviates from a certain position when going there multiple times). The volume in which the robotic arm can travel is called the working envelope (rear of robot is typically restricted), and the axes of rotation are called degrees of freedom (6 or more for higher-end flexibility). A versatile industrial robot can significantly improve the accuracy, precision, and completion times of multiple production tasks while significantly reducing the need for operator involvement.
The industrial robot is task versatile, multi-way programmable, repeatably accurate, and modular with scalable reach and payload. The industrial robot serves a universal function mimicking a human arm, so can fill in (after being programmed) for any repetitive operation not better done by humans; other times, the industrial robot can be directly operator-controlled to act as a mega-arm machine where the high reach, payload, and working envelope are advantaged.

Overview
A laser cutter enables CNC cutting and engraving of metal, wood, and other materials. Laser cutting works by directing the output of a high-power laser, by computer, at the material to be cut. The material then either melts, burns, vaporizes away, or is blown away by a jet of gas, leaving an edge with a high-quality surface finish. Industrial laser cutters are used to cut flat-sheet material as well as structural and piping materials.

Overview
The metal roller sends sheet metal and plate through gaps between cylinders to roll-bend them; this operation is used for producing cylindrical or conical components as well as wiring cylindrical edges.
This roll-bending operation ability is particularly useful for producing standard shapes of metal that would be time-consuming or impossible to form otherwise.
Description
Metal rolling is a centralized industrial process that is done in large-scale (kiloton per day) steel mills. We aim to open-source this technology for use in small-scale (ton per day) flexible fabrication facilities which allow local communities to produce virgin metal from scrap feedstocks.
Description
One type of metal roller uses a pinch rolling operations (lightly grips and moves sheet metal through the machine with a "free" roller to "set" the required bend radius) and pyramid rolling operations (moves plate metal through the machine to "set" the required bend radius). A hydraulically power-driven universal metal roller can be used for all required roll-bending operations.
Solution Statement
The metal roller allows the operator to perform roll-bending operations with ease.

- Frame: the ground-supported structure upon which the rest of the metal roller lies
- Couplers: the mechanisms that convert rotary motion from the hydraulic motor to the cylinders
- Hydraulic Circuit: the set of components that powers the hydraulic motor by sending pressurized fluid through its ports, hence producing rotary motion at the motor shaft
- Adjusters: the mechanisms that allow cylinder movement for different placement configurations on the plane perpendicular to the axis of rotation
- Cylinders: the components that make actual contact with the workpiece for roll-bending.
Status
The Metal Roller is currently in the research phase of development. Prototyping is planned for after product release of the Induction Furnace.

Overview
Agricultural Microcombine (Combine) - a combine is a complex device that cuts, threshes, and winnows grains and field crops of all sorts.
Details
Modern combines are huge devices today, and a smaller one is desirable for a small farm. This is not to say that this design should not be scaleable to larger size, as required to feed larger populations effectively. We propose a hybrid combine, with all parts driven by separate, infinitely speed controllable motors. This eliminates all pulleys and complexity of a single power source powering the entire modern combine. The key here is availability of cost-effective motors and controls, where today, motor controls are prohibitively expensive for such a proposition. OS changes this. With a microcombine under the control of the operator, expensive maintenance is avoided, and full food sufficiency becomes feasible on the tens-of-acres scale.

Status
Current work includes getting information from grain and bean farmers about their needs for a microcombine, the operation modes they'd like, etc. and surveying any commercial equipment available that is similar in scope/scale.

Corners for structural tubing
Corner inserts are one possibility for the Power Cube and for connecting tubular steel members. They would make better use of space that is currently used with the "layering" of tubes in current designs.
Mention was made that adding corners would weaken the overall design, but this has not been proven. A structural analysis would be necessary to find out for sure.
Here is an image of a possible corner: File:PC7s-frame-with-corners.png
