Thanks for downloading!
We'd love to hear from you if the print was successful.
Universal Pellet Extruder - RepRap 3D Printing
Hi Everyone, this is my design for a open-source, Universal plastic pellet /granular material extruder for RepRap (and other) 3D printers.3D printer parts and enhancements

More info is up on my blog here - http://richrap.blogspot.co.uk/2014/12/no-more-filament-quest-for-universal.html
Materials and methods
Just a basic BOM at the moment, most is obvious by looking at the files, and pictures.
Print out parts
Use M4 screws to connect the body parts.
M3 screws for locking in the J-head nozzle and also the motor.
Two designs are uploaded - One using an earlier NEMA17 motor (5mm Shaft), and another one for a Planetary gearboxed NEMA17 - output shaft is 8mm (NEMA23 type)

How is retraction with this?
J head = 1,75mm or 3 mm?
If I look on ebay they look different..
This would work?
Thanks for helping
it hit me .. put a little code like the wipe function into marlin but to make it go to a certain point where it gets filled up automaticly (by servo valve because servo's are already included to marlin) after extrude so muts mm.
I like it going to look into it i was already thinking of building my own filament maker whit pallets
but this is kinda nice for the smaller parts i designed a few complete heads now .. i would lookin
to the possibility to mount a bigger resevoir and a optic sensor for when it runs out and make it interact whit the filament sensor settings inside marlin so you can refil it ontime
I am building a similar design but instead of directly using this as my extruder i am combining it with a 1.5mm nozzle to extrude usable filament from.
Printing this this week! Would also like to know what @dgojanov asked - what changes/settings did you use in cura for a consistent flow rate?
What changes did you need to make in CURA to control output flow of material
Hi, awesome work, cant wait to try it. i would like to know if i can fix this extruder in a Delta 3d printer. thanks.
- Printed on:
- Ultimaker - The Ultimaker 2
- Awesome parts, good tolerances. Some weird design details but it might just be that I don't understand them yet.
Hello, excellent invention. Did you prove it with wax?
