Paste / Clay Extruder

thingiverse

This is an open source paste extruder that I have been researching and developing for about 9 months now. Below are the parts you will need to build your own. 2' Tube from McMaster Carr: https://www.mcmaster.com/8585k38 Hardware Kit I use: https://www.amazon.com/gp/product/B07H4MG7TC/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 High Torque NEMA 23 stepper motor https://openbuildspartstore.com/nema-23-stepper-motor-high-torque-series/ Lock Collar x2 https://openbuildspartstore.com/lock-collar/ Flexible Tube - This tube connects the nozzle to the front of the extruder. You can cut it short as a small safety measure for crashing it into the table (this was developed for a 6 axis robotic arm) or you can use the full length of the tube to keep the reservoir mounted off of the toolhead. https://www.homedepot.com/p/Everbilt-5-8-in-O-D-x-3-8-in-I-D-x-10-ft-PVC-Braided-Vinyl-Tube-HKP002-PVC001/303132532 I'll update this if you should need anything else but I believe that's all you'll need to get going. Oh, and clay of course. But pick your own and find your own mix that works for your needs! To get you started, try Stoneware Cone 10 clay with about a 30% water ratio.
