filastruder

Affordable filament extruder on Kickstarter

With Filastruder you simply setting the desired temperature for extrusion and wait until it warms up. Then you fill the hopper with pellets and turn on the gearmotor. Plastic will begin extruding and the resulting filament can be wound onto a spool using a normal hand drill, or through a printed spool winder.

Specifications:

Extrusion Rate: 6-18 inches/minute (2-5 lbs/day)
Extrusion Temperature: Tested with 170-210°C (others may be possible)
Size: 18″x6″x6″
Noise: 50dBA @ 3ft
Power: 110VAC, 100 watts peak, 50 watts average
Entire assembly is grounded for safety, and main power connection is fused.

According to Tim Elmore, the design has been refined based on beta testers’ feedback. “The majority of our beta testers use 1.75mm filament, and report variances of +/-0.05mm or so. A few beta testers have set the Filastruder up for 3.0mm filament, and report variances of about +/-0.10mm.”

Filastruder’s Kickstarter campaign offers Kit versions and Assembled versions. Approximately 3-4 hours assembly time is required for the kit version, as well as a drill, dremel, and basic hand tools. As of writing, all kit versions ($175~200) are sold out. Fully assembled Filastruder with enclosure will cost you $300, with estimated delivery in June.

Still wondering when you can make filament at home? Comparing to the cheap cost of raw plastic pellets, 3D printer filament is way too expensive. Tim Elmore, a Mechanical Engineering PhD student at the University of Florida and his friend Allen Haynes launched Filastruder, a filament-making machine on Kickstarter that allows you to produce filament on demand.
