I want to give people production power. I have a Master&#039;s in engineering physics and love self-replication. It is my tool to create and distribute production power. I love it in ideas, in free software, in RepRaps, in workshops and in complete enterprises. &lt;br /&gt;

=== Lyman Filament Extruder V6 ===&lt;br /&gt;
&#039;&#039;From Wikipedia, the free encyclopedia&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
The Lyman filament extruder is a device for making 3-D printer filament suitable for use in 3-D printers like the RepRap. It is named after its developer Hugh Lyman and was the winner of the Desktop Factory Competition.&lt;br /&gt;
&lt;br /&gt;
It is open source hardware and all of the plans can be downloaded from Thingiverse&lt;br /&gt;
&lt;br /&gt;
The goal of the Desktop Factory Competition was to build an open source filament extruder for less than $250 in components can take ABS or PLA resin pellets, mix them with colorant, and extrude enough 1.75 mm diameter ± 0.05 mm filament that can be wrapped on a 1 kg spool. The machine must use the Attribution-ShareAlike 3.0 Unported (CC BY-SA 3.0).&lt;br /&gt;
&lt;br /&gt;
The use of DIY filament extruders like the Lyman can significantly reduce the cost of printing with 3-D printers. The Lyman filament extruder was designed to handle pellets, but can also be used to make filament from other sources of plastic such as post-consumer waste like other RecycleBots. Producing plastic filament from recycled plastic has a significant positive environmental impact.&lt;br /&gt;

=Filament Winders=&lt;br /&gt;
From Tobben - The windings on the spools depicted on Filawinder&#039;s home page is not as ordered as Lyman manages to get them.&lt;br /&gt;
Ordered windings are important to avoid tangles and print failures.&lt;br /&gt;
&lt;br /&gt;
This video shows Filawinder&#039;s very simple approach anyways:&lt;br /&gt;
https://www.youtube.com/watch?v=2rnxNLFvuD4&lt;br /&gt;
&lt;br /&gt;
This video shows that Lyman gives windings tension using Latex rubber pinch rollers to get ordered windings.&lt;br /&gt;
https://youtu.be/H6h1yDzoPMU?t=1m10s&lt;br /&gt;
&lt;br /&gt;
Filawinder uses an optical sensor where Lyman uses a pair of microswitches.&lt;br /&gt;
Optical gives more resolution.&lt;br /&gt;
I don&#039;t know if it makes a practical difference.&lt;br /&gt;
&lt;br /&gt;
Helix loopers can be used to place the filament orderly on the spool.&lt;br /&gt;
Video of Russ&#039; helix looper in operation:&lt;br /&gt;
https://youtu.be/vdEXPOo4v64?t=12m42s&lt;br /&gt;
Hugh Lyman has a helix looper (called &amp;quot;Worm Gear&amp;quot;) published under a CC-BY licence in this repo: http://www.thingiverse.com/thing:380987 .&lt;br /&gt;
&lt;br /&gt;
I don&#039;t know how Lyman and Russ regulates helix rotation speed.&lt;br /&gt;
It should depend on current spool radius (how much filament is already winded up).&lt;br /&gt;
&lt;br /&gt;
=Calculations=&lt;br /&gt;
*600 feet per minute for professional extruder lines&lt;br /&gt;
*One kg spool of filament - 1000 feet long for 1.75 mm, 1/3 that for 3 mm&lt;br /&gt;
*One kg/hr for filabot. This one is 4 feet per minute - [https://www.grainger.com/product/39RL71?gclid=COOqh8CczNACFdgZgQodei4Ohw&amp;amp;cm_mmc=PPC:GOOGLEPLAA-_-Machining-_-Machinery-_-39RL71&amp;amp;AL!2966!3!50916766197!!!s!104633677557!&amp;amp;s_kwcid=AL!2966!3!50916766197!!!s!104633677557!&amp;amp;ef_id=VtfYBQAABF9hvLrN:20161128195018:s]&lt;br /&gt;

=== Lyman Filament Extruder V6 ===&lt;br /&gt;
&#039;&#039;From Wikipedia, the free encyclopedia&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
The Lyman filament extruder is a device for making 3-D printer filament suitable for use in 3-D printers like the RepRap. It is named after its developer Hugh Lyman and was the winner of the Desktop Factory Competition.&lt;br /&gt;
&lt;br /&gt;
It is open source hardware and all of the plans can be downloaded from Thingiverse&lt;br /&gt;
&lt;br /&gt;
The goal of the Desktop Factory Competition was to build an open source filament extruder for less than $250 in components can take ABS or PLA resin pellets, mix them with colorant, and extrude enough 1.75 mm diameter ± 0.05 mm filament that can be wrapped on a 1 kg spool. The machine must use the Attribution-ShareAlike 3.0 Unported (CC BY-SA 3.0).&lt;br /&gt;
&lt;br /&gt;
The use of DIY filament extruders like the Lyman can significantly reduce the cost of printing with 3-D printers. The Lyman filament extruder was designed to handle pellets, but can also be used to make filament from other sources of plastic such as post-consumer waste like other RecycleBots. Producing plastic filament from recycled plastic has a significant positive environmental impact.&lt;br /&gt;

=Filament Winders=&lt;br /&gt;
From Tobben - The windings on the spools depicted on Filawinder&#039;s home page is not as ordered as Lyman manages to get them.&lt;br /&gt;
Ordered windings are important to avoid tangles and print failures.&lt;br /&gt;
&lt;br /&gt;
This video shows Filawinder&#039;s very simple approach anyways:&lt;br /&gt;
https://www.youtube.com/watch?v=2rnxNLFvuD4&lt;br /&gt;
&lt;br /&gt;
This video shows that Lyman gives windings tension using Latex rubber pinch rollers to get ordered windings.&lt;br /&gt;
https://youtu.be/H6h1yDzoPMU?t=1m10s&lt;br /&gt;
&lt;br /&gt;
Filawinder uses an optical sensor where Lyman uses a pair of microswitches.&lt;br /&gt;
Optical gives more resolution.&lt;br /&gt;
I don&#039;t know if it makes a practical difference.&lt;br /&gt;
&lt;br /&gt;
Helix loopers can be used to place the filament orderly on the spool.&lt;br /&gt;
Video of Russ&#039; helix looper in operation:&lt;br /&gt;
https://youtu.be/vdEXPOo4v64?t=12m42s&lt;br /&gt;
Hugh Lyman has a helix looper (called &amp;quot;Worm Gear&amp;quot;) published under a CC-BY licence in this repo: http://www.thingiverse.com/thing:380987 .&lt;br /&gt;
&lt;br /&gt;
I don&#039;t know how Lyman and Russ regulates helix rotation speed.&lt;br /&gt;
It should depend on current spool radius.&lt;br /&gt;
&lt;br /&gt;

=== Lyman Filament Extruder V6 ===&lt;br /&gt;
&#039;&#039;From Wikipedia, the free encyclopedia&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
The Lyman filament extruder is a device for making 3-D printer filament suitable for use in 3-D printers like the RepRap. It is named after its developer Hugh Lyman and was the winner of the Desktop Factory Competition.&lt;br /&gt;
&lt;br /&gt;
It is open source hardware and all of the plans can be downloaded from Thingiverse&lt;br /&gt;
&lt;br /&gt;
The goal of the Desktop Factory Competition was to build an open source filament extruder for less than $250 in components can take ABS or PLA resin pellets, mix them with colorant, and extrude enough 1.75 mm diameter ± 0.05 mm filament that can be wrapped on a 1 kg spool. The machine must use the Attribution-ShareAlike 3.0 Unported (CC BY-SA 3.0).&lt;br /&gt;
&lt;br /&gt;
The use of DIY filament extruders like the Lyman can significantly reduce the cost of printing with 3-D printers. The Lyman filament extruder was designed to handle pellets, but can also be used to make filament from other sources of plastic such as post-consumer waste like other RecycleBots. Producing plastic filament from recycled plastic has a significant positive environmental impact.&lt;br /&gt;

=Filament Winders=&lt;br /&gt;
From Tobben - The windings on the spools depicted on Filawinder&#039;s home page is not as ordered as Lyman manages to get them.&lt;br /&gt;
Ordered windings are important to avoid tangles and print failures.&lt;br /&gt;
&lt;br /&gt;
This video shows Filawinder&#039;s very simple approach anyways:&lt;br /&gt;
https://www.youtube.com/watch?v=2rnxNLFvuD4&lt;br /&gt;
&lt;br /&gt;
This video shows that Lyman gives windings tension using Latex rubber pinch rollers to get ordered windings.&lt;br /&gt;
https://youtu.be/H6h1yDzoPMU?t=1m10s&lt;br /&gt;
&lt;br /&gt;
Filawinder uses an optical sensor where Lyman uses a pair of microswitches.&lt;br /&gt;
Optical gives more resolution.&lt;br /&gt;
I don&#039;t know if it makes a practical difference.&lt;br /&gt;
&lt;br /&gt;
Helix loopers can be used to place the filament orderly on the spool.&lt;br /&gt;

I want to give people production power. I have a Master&#039;s in engineering physics and love self-replication. It is my tool to create and distribute production power. I love it in ideas, in free software, in RepRaps, in workshops and in complete enterprises. &lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;= Tobben&#039;s notes from 2 Nov 2016 =&lt;br /&gt;
Web search shows that many have built their own DIY plastic shredders.&lt;br /&gt;
Most reach good enough performance for small scale plastic recycling.&lt;br /&gt;
&lt;br /&gt;
Most designs utilize rotating cylinders (sometimes called rotors or shafts) with 2-6 teeth per rotation.&lt;br /&gt;
The teeth are commonly mounted along a &amp;quot;wave shaped&amp;quot; path on the cylinder perimeter.&lt;br /&gt;
&lt;br /&gt;
Things that differentiate common designs are:&lt;br /&gt;
# &#039;&#039;&#039;Rotor Construction and Structure&#039;&#039;&#039;&lt;br /&gt;
## Layers of sheets with teeth, small machine example: https://youtu.be/VFIPXgrk7u0?t=10m&lt;br /&gt;
## Solid cylinder, complex tooth shapes, bigger machines examples: https://youtu.be/NgwyVDjr0A0?t=21s and https://youtu.be/T40quUYF4qo?t=1m42s&lt;br /&gt;
# &#039;&#039;&#039;Number of Rotors&#039;&#039;&#039;&lt;br /&gt;
## Two-rotor Shredder example: https://www.youtube.com/watch?v=LuhZM5cP3VQ&lt;br /&gt;
&lt;br /&gt;
Very simplified, one can say that some shredders &amp;quot;grip&amp;quot; and &amp;quot;tear apart&amp;quot; their material while others function more like a coarse file.&lt;br /&gt;
Most DYI designs use &amp;quot;grip and tear&amp;quot;. Their rotors are either:&lt;br /&gt;
#&#039;&#039;&#039;Two rotors built from layers&#039;&#039;&#039;&lt;br /&gt;
## Open Source examples: [http://filamaker.eu/product/mini-shredder/ Mini Shredder] and [https://www.youtube.com/watch?v=iu5Sz3p-ihw Jason Knights Shredder]&lt;br /&gt;
#&#039;&#039;&#039;One rotor built from layers&#039;&#039;&#039;&lt;br /&gt;
## Open Source example: [https://preciousplastic.com/en/videos/build/shredder/ Precious Plastics shredder]&lt;br /&gt;
&lt;br /&gt;
These are suited to shred thin plastic like bottles, cups and thin 3D prints.&lt;br /&gt;
Potential problems with &amp;quot;grip and tear&amp;quot; (often realized with two-rotor-designs and large hook shaped teeth):&lt;br /&gt;
* Safety. Hooks might grip and chew on fingers.&lt;br /&gt;
* Grips only relatively flat or edged objects. Won&#039;t shred to big and/or round objects.&lt;br /&gt;
* Shred output size is rather random. Re-shredding is sometimes necessary.&lt;br /&gt;
&lt;br /&gt;
Single-rotor shredders with &amp;quot;grinding&amp;quot; teeth work better on more massive and/or round objects. Proprietary example: [https://youtu.be/K7yNFy90l-M?t=1m13s WEIMA plastic shredder Spider 1500].&lt;br /&gt;
Potential benefits of single-rotor shredders:&lt;br /&gt;
* Easily enclosed by tube sections. Good for maintainability. Proprietary example: https://youtu.be/iJNT1Cf_dJE?t=19s&lt;br /&gt;
Potential benefits of &amp;quot;grinding&amp;quot; compared to &amp;quot;grip-and-tearing&amp;quot;:&lt;br /&gt;
* Predictable shred size. Less need for re-shredding.&lt;br /&gt;
&lt;br /&gt;
== Conclusions from 2 Nov 2016 ==&lt;br /&gt;
For recycling of smaller 3D prints, both the Precious Plastic Shredder and the Mini Shredder seems good enough.&lt;br /&gt;
Precious Plastic seems to have the most active community.&lt;br /&gt;
I therefore advice [http://opena.info/ Opena] to join the Precious Plastic (Shredder) community while working on a 3D print recycling workshop.&lt;br /&gt;
Should the need emerge to shred larger 3D prints, I recommend designing a single-rotor shredder with small square teeth (as opposed to large gripping teeth. Example: https://www.youtube.com/watch?v=laf8eKM7hnA&lt;br /&gt;

== Open Source Extruder Projects ==&lt;br /&gt;
=== Lyman Filament Extruder V6 ===&lt;br /&gt;
&#039;&#039;From Wikipedia, the free encyclopedia&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
The Lyman filament extruder is a device for making 3-D printer filament suitable for use in 3-D printers like the RepRap. It is named after its developer Hugh Lyman and was the winner of the Desktop Factory Competition.&lt;br /&gt;
&lt;br /&gt;
It is open source hardware and all of the plans can be downloaded from Thingiverse&lt;br /&gt;
&lt;br /&gt;
The goal of the Desktop Factory Competition was to build an open source filament extruder for less than $250 in components can take ABS or PLA resin pellets, mix them with colorant, and extrude enough 1.75 mm diameter ± 0.05 mm filament that can be wrapped on a 1 kg spool. The machine must use the Attribution-ShareAlike 3.0 Unported (CC BY-SA 3.0).&lt;br /&gt;
&lt;br /&gt;
The use of DIY filament extruders like the Lyman can significantly reduce the cost of printing with 3-D printers. The Lyman filament extruder was designed to handle pellets, but can also be used to make filament from other sources of plastic such as post-consumer waste like other RecycleBots. Producing plastic filament from recycled plastic has a significant positive environmental impact.&lt;br /&gt;

=== Lyman Filament Extruder V6 ===&lt;br /&gt;
&#039;&#039;From Wikipedia, the free encyclopedia&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
The Lyman filament extruder is a device for making 3-D printer filament suitable for use in 3-D printers like the RepRap. It is named after its developer Hugh Lyman and was the winner of the Desktop Factory Competition.&lt;br /&gt;
&lt;br /&gt;
It is open source hardware and all of the plans can be downloaded from Thingiverse&lt;br /&gt;
&lt;br /&gt;
The goal of the Desktop Factory Competition was to build an open source filament extruder for less than $250 in components can take ABS or PLA resin pellets, mix them with colorant, and extrude enough 1.75 mm diameter ± 0.05 mm filament that can be wrapped on a 1 kg spool. The machine must use the Attribution-ShareAlike 3.0 Unported (CC BY-SA 3.0).&lt;br /&gt;
&lt;br /&gt;
The use of DIY filament extruders like the Lyman can significantly reduce the cost of printing with 3-D printers. The Lyman filament extruder was designed to handle pellets, but can also be used to make filament from other sources of plastic such as post-consumer waste like other RecycleBots. Producing plastic filament from recycled plastic has a significant positive environmental impact.&lt;br /&gt;

=== Lyman Filament Extruder V6 ===&lt;br /&gt;
&#039;&#039;From Wikipedia, the free encyclopedia&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
The Lyman filament extruder is a device for making 3-D printer filament suitable for use in 3-D printers like the RepRap. It is named after its developer Hugh Lyman and was the winner of the Desktop Factory Competition.&lt;br /&gt;
&lt;br /&gt;
It is open source hardware and all of the plans can be downloaded from Thingiverse&lt;br /&gt;
&lt;br /&gt;
The goal of the Desktop Factory Competition was to build an open source filament extruder for less than $250 in components can take ABS or PLA resin pellets, mix them with colorant, and extrude enough 1.75 mm diameter ± 0.05 mm filament that can be wrapped on a 1 kg spool. The machine must use the Attribution-ShareAlike 3.0 Unported (CC BY-SA 3.0).&lt;br /&gt;
&lt;br /&gt;
The use of DIY filament extruders like the Lyman can significantly reduce the cost of printing with 3-D printers. The Lyman filament extruder was designed to handle pellets, but can also be used to make filament from other sources of plastic such as post-consumer waste like other RecycleBots. Producing plastic filament from recycled plastic has a significant positive environmental impact.&lt;br /&gt;

&lt;br /&gt;
I want to give people production power. I have a Master&#039;s in engineering physics and love self-replication. It is my tool to create and distribute production power. I love it in ideas, in free software, in RepRaps, in workshops and in complete enterprises. &lt;br /&gt;

&lt;div&gt;RepRap 3d-printer axes are often stepper motor driven. Modern proprietary 2d-printers almost always use servos (DC motor + encoder) instead. Servo-based drives are often lighter and cheaper as well as featuring closed loop control.&lt;br /&gt;

I want to give people production power. I have a Master&#039;s in engineering physics and love self-replication. It is my tool to create and distribute production power. I love it in ideas, in free software, in RepRaps, in workshops and in complete enterprises. &lt;br /&gt;
