Description

Okay, this is not quite done, but I thought I'd throw it out there anyway.

This version is less prone to cracking. Instead of a washer and nut, there is an M6 tapped hole in a piece of aluminum. But best of all, two can be bolted together to form a dual head extruder. Yes, you can have one or two of the same extruder! I'm working on a mount for this right now.

See my YouTube videos of previous versions for theory of operation (http://www.youtube.com/watch?v=HMjVrmLJvIU) and how quickly the filament can be changed (http://www.youtube.com/watch?v=z_isuzpvjBc)

A kit would be nice and certainly an improvement. I've been happily using the extruder I've designed for a few months. I don't know when the MK5 extruder stuff is coming out, but when it does it will probably include the improvements I've made as well as a whole lot more.
What a great design! When can I buy a 'kit' of the plexiglas pieces to build one up using parts from a torn down mk4 extruder? I've tried 3 builds to get consistant extruding from 2 different plastruder mk4s with no luck. Sure would like to try your version out.
I'm assuming you ar eusing Delrin for it's low co-efficient of friction... so what about using PTFE ( ie Teflon ) as used in the thermal barrier, which has an even lower co-efficient, and you are then reducing the number of different materials that need sourcing.

<p>Very nice. Is the aluminium there to cool the top section of the barrel (does it get hot?) or mostly for mechanical strength? I have a heat sink against my PEEK barrel, for both purposes and it works fairly well.</p>

<p>People have been seeing their heater barrels pop out of the thermal barrier. Placing a nut behind the washer fixes this. I drilled and tapped an M6 hole in a piece of aluminum to give the same effect in the small space I had when two extruders are mounted together.</p>

<p>still using 6mm acrylic? very nice refinements!</p>

<p>I'm glad you like it. I'm not sure of the thickness. It's supposed to be 1/4 inch, but acrylic is not always the stated thickness.</p>

<p>Looks good, nice work Mr PAX.</p>
