Stepper extruder for siliconecartridges

Printed parts:

  • Back plate
  • Front plate
  • Pulley big
  • Pusher sled
  • Pusher clamp


building the hardware for adding to an Ultimaker.
I hope to get some empty 350ml silicone cartridges for other print media.

I still need to design the bowden holding parts and the nozzle..
These must be easy exchangable or even single use.
Since you cant clean up a silicone-mess that easy.


  • two linear rails and Linear Bearings.. in my case O=16mm rails
  • Treaded rod with nut.. what i had around in my parts bin
  • two ballbearings fitting to the treaded rod.. mine are o=6mm O=19mm h=6mm
  • Stepper motor Nema17
  • some more treaded rods and bolts.. in my case 4mm ones
  • XML Belt and XML Pulleys.. in my case

Cool idea! Not sure how far you've gotten on this, but one thought: if you use a bowden tube, you'll have to find some way to clean out the remaining silicone before it hardens or you'll need a new bowden tube every time. One (perhaps silly) idea: just print a short cheap nozzle that fits over the existing exit point. Alternative idea: print a jig or something that helps produce a consistent sized hole for extruding directly from the cartridge and just mount the whole thing on the printer. (I have a Printrbot+, so there is space for this--not sure about an Ultimaker, though).

i cant put the cartridge in the ultimaker because we have a moving head here, it would shake and rattle itself into pieces, if i put more weight (350ml is a lot) ontop of my moving parts...
if i dont use silicone, but clay or plaster i cant use it multiple times.. but a hose and a nozzle dont cost me too much to change from time to time...

are these cartridges the size a caulking gun uses?

 jep the 350ml ones

more pics and parts to come soon..
