CAPA Extruder Pushes Filament
One video of the completed CAPA extruder screw mechanism extruding a 3mm CAPA filament:
I'll add the clamp and hot nozzle later (waiting on some PTFE rod for that).
It's probably different with CAPA, but I found that with HDPE and HPP getting the Mk 2 to push the filament is one thing while getting it to push the filament with enough force into the heated extruder barrel to actually extrude is quite another. :-(
Zaphod will be continuing service as a multiple head testbed until retired into the garden shed. Probably when the PIC software is out of date - its steppers aren't compatible with the current Darwin design.
Oh, apparently that video was one of YouTube's most viewed science clips yesterday!
Congratulations! I'm looking forward to owning a reprap in a couple years or so.

ReplyDeleteIf I understand correctly, you now have the makings of two extruder heads: one made from ABS on a Stratasys and one made from CAPA on Zaphod.
ReplyDeleteI'm assuming you're working toward building a Darwin. Planning on selling Zaphod when your done? :^)

Hmmm, If we scan him and provide good pictures, they can just make a copy from their McClintock 12 or will it be a Pauling 7?
ReplyDeleteSome parts of Zaphod are already headed for the Science Museum in London.

Cool! When did this happen?
