# Summary
**Update - July 2018** - I have continued to develop this extruder and the clay printing process in general. For posts about the development process please follow this link: https://plus.google.com/u/0/+TomLauerman
This is an open-source clay extruding print head that can be used on numerous 3d printers.
It is a work in progress. It is based on pioneering work by Unfold http://www.thingiverse.com/unfold/about ,
Jonathan Keep http://www.thingiverse.com/JKeep/about , the Wasp Group http://ow.ly/Zt2tz , and more.
The project was initiated by Tom Lauerman at Penn State University, School of Visual Arts https://sova.psu.edu/ and is being
developed in collaboration with Engineering Students as part of the University's Learning Factory program http://www.lf.psu.edu/ .
The work is supported, in part,
by Penn State’s Center for Innovative Material Processing through Direct Digital Deposition (CIMP-3D, http://www.cimp-3d.org )
This is only the print head portion of the design. An entire printer system is in active development and can be found here:
https://github.com/Tom-Lauerman/Bricoleur . Please follow my newer clay printer developments here: https://plus.google.com/+TomLauerman
For a complete parts list check the "Bill Of Materials" section. The print head costs about $30 USD to build (excluding printed parts).
A recent video of the system in use can be found here: https://www.youtube.com/watch?v=JbxZZMp6b8A
An older video of the whole system can be found here: https://youtu.be/X4ksTKWRqvM .

# Print Settings
Printer Brand: RepRap
Printer: Prusa i3
Rafts: No
Supports: No
Resolution: .2, .3, or .4mm
Infill: 20%
Notes:
I printed in PLA just because that is what I had on hand. The parts are not subjected to any heat, so just about any materials would work.
# Post-Printing
After printing,
remove support columns from extruder body.
A pliers or scissors should do just fine.
# Bill Of Materials
## All the parts needed to build this open source clay extruder
1. Printed extruder
2. Printed Base
3. Nema 17 stepper motor (I purchased mine from Lulzbot: http://ow.ly/ZsSt5 , $13.95)
4. Aluminum coupler - 5mm on both ends. (I purchased mine from Inventables: http://ow.ly/ZsSMe , $6.95)
5. 1/2" Flat faucet washer. I purchased a pack of 10 at Home Depot for $1.69, http://ow.ly/ZsTrs (the outside dimension of this rubber washer is 3/4", the inside diameter is 1/8". It is 1/8" thick. (Why is this called a 1/2" washer?))
6. Deck Screw 1/4" x 4". I bought mine at a local Ace Hardware for $1.60. I used a "Timber-Tite" brand - here's a pack of 50 at Amazon, http://ow.ly/ZsUqC . I'd imagine any similar screw would work, perhaps better.
7. Cake decorating tips. This is the "nozzle" of the print head. There are numerous shapes and sizes available, all of which could work potentially. Two brands which fit this extruder are Ateco http://ow.ly/ZsV34 , and PME http://ow.ly/ZsV8V . The Ateco ones are about $1 each, the PME are about $6 each. Cake decorating Pros rave about the more expensive PME tips http://ow.ly/ZsVdR .
8. 3/8" x 3/8" push fit male adapter. I got mine at Lowe's for $3.49. http://ow.ly/ZsXY5 . Here's he same one on Amazon http://ow.ly/ZsY08
9. (4) M3 x 14mm Socket Cap Screws. Approx. $0.15 at any hardware store.
10. (2) M4 x 20mm Socket Cap Screws. Approx. $0.15 at any hardware store.
11. (2) M4 Wing Nuts. Approx. $0.75 at any hardware store.
12. (totally optional) plastic thumb screw heads M3 & M4. These make it easy to remove screws without a wrench. I purchased these at McMaster Carr http://ow.ly/Zt07K , http://ow.ly/Zt0b9
13. (totally optional) 4 pin JST connectors. I solder these onto my motor wires to make attaching and detaching the extruder motor really simple. I switch between plastic and clay printing frequently and am always swapping print heads. I bought these on Amazon http://ow.ly/Zt1kb
Total Cost: $29.58 (excluding printed parts)
Printed Extruder (cylinders in the middle are supports, to be removed after printing)
Printed Base (for Prusa i3 printer)
Nema 17 motor - I purchased mine from Lulzbot
Aluminum coupler - 5mm hole on both sides. I purchased mine from Inventables.com
Flat faucet washer (O.D. 3/4
1/4
Cake frosting tips. All shapes and sizes could potentially work. Ateco and PME brands fit this extruder perfectly.
Watts PL-3026 Push Male Adapter, 3/8-Inch x 3/8-Inch NPT. Lowes / Home Depot / Amazon stock these
M3 x 14mm socket cap screw
M4 x 20mm socket cap screw
M4 Wing Nut
Plastic thumb screw head
# Clay Printing Settings
These are Cura slicing settings we found to work well when printing with clay using a Prusa I3 printer. Thanks Leo!
