Versions of 3D Printers built by OSE
Note the main categories are Pro, Pro 2, and Pro 3 - based on bed size. Then there are v2 etc of each. So you can have D3D Pro v2 - which is an iteration on the D3D Pro (8" bed) - which is not the same as D3D Pro 2 - which is a larger printer (12" bed). Same applies to the other branch - D3D Universal.
- D3D Giga - partial build up to beginning of testing axis motion. Next: needs improvement of Z motion as the belts continue to skip, using 4 9 mm belts.
- D3D Universal v21.06 - D3D Universal v3. Integrated Z motor, separated the bed for bed extension possibility.
- D3D Pro v21.03.15 - AKA D3D Pro 3 v2b. Copy of D3D Pro 3v2 for production printing and testing.
- D3D Pro v21.03.14 - AKA D3D Pro 3 v2 Equivalent of D3D Pro v2 - meaning monolithic frame pieces. But larger size, the 18" bed.
- D3D Pro v21.02 - D3D build in India by Ashwin based on D3D Pro v20.07
- D3D Pro 3 v20.07 - D3D Pro 3, second build towards product release. \First Pro 3 build was D3D v20.04.27.
- D3D Universal v20.07. AKA Universal v2. The first major revision of Universal. 3D printed base to streamline design and locate mounting points. One-piece Universal Axis components. Has Extruder files ported from D3D Universal, so see earlier versions there. For 1-piece printing, reqiures a D3D Pro 3, but base can be printed in parts with smaller machines and glued together.
- Stable Release Version - D3D Pro v20.07 - The first major revision of Pro, aka D3D Pro v2. next generation, using 1-piece universal axis pieces - D3D Universal v20.07. Higher modularity, easier frame mounting, part count reduced from 46 to 26 for each Universal Axis. Note that new corner pieces are being printed at 105% compared to earlier versions.
- D3D Universal Hamburg - D3D_Universal_With_Dual_Z_Axis_Version_0_2_0
- D3D Universal Hamburg - D3D_Universal_With_Dual_Z_Axis_Version_0_1_0
- D3D v20.04.27. 18" bed, 1800W heater. AKA D3D Pro 3.
- D3D v20.04 - 12" bed, 1200W heater. AKA D3D Pro 2. Moved back to 3 wire endstops.
- D3D Mega v19.12 - 2'x2' print bed for printing chairs, rubber tracks for tractors, foundation forms, and more. In progress.
- D3D Universal - Milestone of an industrial-grade 1.75 mm / 3mm OSE extruder design has been reached.
- D3D v19.11 - Current production model using corners that fit 1/8"x1.5" angle metal.
- D3D v19.06 Mega - concept only
- D3D v19.06 - iteration prior to angle frame
- D3D Simple - a 3 axis version with moving bed.
- D3D v19.04 - Eco edition. Upgraded to 24V control system, silent stepper drivers, 500W heatbed for 1 minute bed heatup time, and insulated heatbed for 30%-60% lower energy consumption while printing. Added built-in GFCI electrical safety breaker as a standard feature. Uses the Titan Aero extruder.
- D3D v19.02 - Similar to D3D v18.10 but using 12" frame, 8" print bed, and Titan Aero with Volcano nozzle. New end stops (hung on rods) optimized for space, and Y parallel optimized for automatic parallel of axes. In order to achieve larger print area with smaller frame, we introduced the overslung extruder design. Thus, the 2 main improvements are overslung extruder and auto-parallel on the y axis.Future work: rubber-optimized extruder at low cost using D3D Mill for aluminum milling. See Y Axis Auto-parallel.
- D3D @ Fontys Sittard - Netherlands
- D3D_Mini_PVC - 2019 February current work on a smaller, low-cost version. Optimization goal for fast, high quality printing via frame stabilization.
- D3D v18.12 - new omnidirectional fan shroud from Lulzbot Mini 2. OSE build in January, and replicated Feb 2019 at Highland Community College.
- D3D v18.11 - 12" bed version.
- D3D v18.10 - (renamed from D3D v18.09.2 for simplicity). Uses Titan Aero. Full Product Release as in the D3D Manaul v18.10 - the 3D Printer Manual - which is the most exhaustive, 358 page build guide.
- D3D 18.10.1 - 2' print bed, one day build prototype - bed lift capacity was not there. Next time - to use 1" universal axis for robustness.
- D3D v18.09.1 - back to Titan Aero
- D3D v18.09 - Remove Magnets, Use JB Weld + Plastic Bearings.
- D3D v18.08 - Main Trunk Continued
- D3D v18.07 - Main trunk. 8" bed.
- D3D v18.06.21 - Oregon Build. Main trunk, 8" bed.
- D3D v18.06.12 - Ruslan in Hamburg - fork with aluminum frame.
- D3D v18.06 - Lawrence Build. Main trunk, 8" version.
- D3D v18.04 - PVC pipe, 8" bed
- D3D_Ohio_v18.02 - PVC pipe 12" bed
- D3D v18.01 - 12" bed, steel frame
- D3D Saudi Arabia
- D3D Australia - by German log
- D3D Hamburg - Babasile Daniel
- D3D Germany - Oliver
- D3D - builds started in 2017 - using the Universal Axis system. Open Source Ecology headquarters.
- Folgertech Prusa i3 - 2016; deprecated, entry level model for quick learning; not high on OSE Spec of modularity + scalability.
- Kittaz - 2014
Other D3D Universal Axis Machines
- As of 12/3/18 v18.10 - known bugs are: positive bump endstop holder does not fit around motor just by 1 mm, whereas magnets worked before as they had play. Print Cooling Fan: needs nozzle optimization. X axis mounting: needs procedure optimization for axis tightness. Print area: using 2016 extruder holder eats up bed space; need to optimize bed space. Print volume: optimize extruder mounting to access 3" of additional vertical space with horizontal X axis mounting. Needs: 3D Printer Workbench Specification. End cable chain: needs bigger hole. Fan mount: thinner + 100% print
Production Engineering Improvements
- Idler detail - nut catcher cleaning + half circle cleaning
- Carriage - half circle cleaning
- Motor - hole cleaning, nut catcher cleaning
- Endstops - get rid of them via trinamic or modify bump version
- Spool holder - hole fit
- Sensor holder - sensor fit
Hint: Note that to design new versions of the 3D printer, you want to use small, simple files. We have ones ~20k for each axis.
- Note that D3D_Part_Library#Assembly_Index contains the simplified assemblies. These are to be used any time that a new version of the 3D printer is to be designed from scratch.
- Simplified axis files - X, Y, Z - the smallest ones today are also used on the D3D CNC Circuit Mill
- D3D Integration has files that are on the order of 5MB and 1MB for each axis. Still too large for prototyping.
