Hi!
For the last months i have been playing/designing a peristaltic extruder for my printer.
Here you can see some demos:

I have start documenting everything here:

I would thank any opinions, comments, suggestions or feedback.
Thanks a lot!

Very cool. A butane torch attachment and bread dough and you can print a PB&J. smiling smiley

A butane torch definitely would add some fun winking smiley

Second documentation part is already up!

Might be interesting to see a print using something like this epoxy-plastic [www.kraftmark.biz] for comparison against one of the "smallest print" contests. [forums.reprap.org]

I would really like a plastic hot-end and a punp to try to print a seal between two plastic parts. I feel like if multi-tool is going to take off, we need better examples of possibilities. smiling smiley

This could also be useful for dosing a hydroponic farm that does not use a big closed loop system. Move, draw water, measure pH/PPM, formulate (balance of 3 solutions), dispense, measure .. then on to the next.

I think you are right as a peristaltic pump, has lots of other applications, also i think might not be the best design. As an extruder really needs improvements and specially try lots of different materials. Syringe based extruders normally have more "pumping" force since the material doesnt need to "travel" that much, hence printing thicker materials is easier, is a matter of lots improvements.

As an example i love how this people use peristaltic extruder in a completely different concept 3d machine.
