Apparently not open source anymore

is that a worm gear extruder like you find on an injection Moulder?

Firstly: I'm getting a friend to make me all the metal and teflon parts :)

Secondly: Is there an alternative motor that can be used? Or even somewhere that has all the specs for the motor so I can look for an alternative?

Thanks :)

Does the auger bit actually work? It looks hollow. Is there specs somewhere for the perfect extruder screw shape? I'm a machinist, could possibly make one.

Are you going to release source files for this? What software are you using for designing this?

Been following this since the beginning. The one thing I can't find and am really curious about, is the extrusion rate. Would love it if anybody had any information.

Finally, this gets a feature! I was beginning to think there was some kind of Makerbot Store conspiracy going on ;) Now, all we need is the blog to catch up... and maybe do something more than simply repeating the items description...

Seriously folks, check out their kickstarter- The implications of future designs have the potential for awesome-a-plenty!

Good work. Do you know the mm per btu? Or do you know what the extruusion rate is in meter per min/hour?

Very, very exciting work! Looking forward to seeing one on my table eating my failed prints!!

That is very cool, especially if you are getting that accurate of filament produced. Something like this could dramatically reduce the cost of printing.

The Screw is a 5/8in auger bit. Look at the BOM for this.

I have not included an assembly drawing yet. I will be uploading that soon.

Why i don't see any specifications about the screw extrusion shape?

Hey guys, did you see this:

It is a competition and here is the challenge:

Drive down the cost of filament by creating a machine. The first team/person to build an open source filament extruder for less than $250*(calculation details below) in components can take ABS or PLA resin pellets, mix them with colorant, and extrude enough 1.75mm diameter +/- .05mm filament that can be wrapped on a 1kg spool.

I was looking at your nozzle and I noticed your extruding at 1.6mm. Wouldn't you want to make it bigger than your final diameter since the plastic would cool and shrink.

Thanks Mouritsen, The filament that it is currently producing is 1.75mm dia. +/- .05mm.

There are no bubbles in the filament. It is some really great stuff. We have printed with our filament and it works great. We have a "youtube" channel where we have a few videos showing the system working.

The Filabot Reclaimer is our system that has a grinder so that you can recycle your old prints, soda bottles, milk jugs.........the list goes on and on.

Good job putting this together so fast. What is the quality of the filament? Is it uniformly round? Is it a consistent thickness? Does it have any bubbles in it? Have you printed with it and if so how does it perform compared to commercially produced filament? I'd be very interested to see a video of it in action.

That is what the Filabot Reclaimer is to do. That has the grinder with it.

Neat. I'd love to see a video of it in operation.

Could Filabot be used to recycle failed prints?
