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.

Description

It's aimed as an open community project, so please get involved, share, develop and enhance the design process. Make upgrades and share both files and experiences so we can make a really good low cost solution for pellet based 3D printing.

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)

CarvedArt commented over 4 years ago

An idea for keeping the hopper topped-up: perhaps a concept similar to that of an automatic waterer. An elevated bin filled with pellets that has a ½ to ¾" tube attached to the bottom. The tube then attaches to the extruder hopper to carry additional pellets. Eliminating the need to park for refills. The pellet flow could be triggered by a simple sensor like those used in agitating paintball hoppers. When it senses movement of pellets it agitates the elevated hopper to maintain the level in the tube.

As for keeping the customizing efforts low an agitating paintball hopper could be used as the elevated bin.

NICOLINI commented over 6 years ago

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.

NICOLINI commented over 6 years ago

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.
