EVAStruder
Description
It fits instead of a wade extruder on a prusa mendel.
With this I could extrude soft part made of EVA.
This design is still on modification, stay tuned.
BE CAREFULL : the hot gun heater is plugged on 220V, prefer using your hot-end heater/controller block.
Instructions
open and cut a cheap 12mm glue gun body made of nylon.
drill an tape the hotend to be able to put a brass M6 drilled thread.
put an hot-end nozzle on it.
assemble everything and run.

Love it! My first 'extruder' was a motor-fed hot glue gun for injecting plaster molds to make flexible pieces. I ended up designing a feed mechanism for the shorter mini glue sticks because I could never get good results from the longer ones. Might be time to dust that off....
Nice!
Can you put some more photos and perhaps - video?
What is the resolution you'r getting with it?
I'll put photos and videos soon.
I first tried with a 0.5mm nozzle, then a 0.8mm which was to big, the eva was leaking by himself without the help of the extruder, so I went back to 0.5mm which seems to work more or less.
I'll try with a 0.3mm, but you have to wait longer and run slower, because the eva has not the time to become soft enough.
EVA is a weird raw material...
cool
you should make the contour of top and bottom follow the curve of the walls.

Awesome! I've been wanting to try using glue gun glue as a support material. This is reminding me to get off my butt and try it.
