Filastruder Kit FAQs

We highly recommend utilizing the Filastruder support forum where you can access useful information and a helpful community. Most importantly, you will find content, including independent verification of quality from Filastruder users. 

How does it work?

Set the desired temperature for extrusion. Allow time to warm up. Fill the hopper with pellets and colorant of your choice, and turn on the gearmotor. 

Plastic will begin extruding from the Filastruder, forming a pile on the floor to be spooled up later. The resulting filament can be wound onto a spool quickly and easily using a normal hand drill, or through a printed spool winder, like the Filawinder.

Do you offer a fully assembled version?

At this time, no. It is possible that a fully assembled version will be offered in the future, though.

What do I need to assemble the kit?

Approximately 3 hours and basic hand tools. 

How big is it?

18”x6”x4”  - It fits comfortably on a standard-size workbench.

Is it loud?

The Filastruder produces about 55dBA at 3ft.  

What about colorants/masterbatch?
You can get colorants (and ABS pellets for that matter), from some of our recommended suppliersTypically, you use natural ABS with a colorant, or masterbatch, as it is called in the industry:

Mix the pellets above with the natural ABS pellets, usually at a 50:1 ratio, or whatever is specified by the manufacturer of the masterbatch. This is the result:

What's the extrusion rate and temperature?

Typical Extrusion Rate: 5-8 hours per kilogram (2.2lbs) (10-36in/min, depending on diameter, material, and temperature) 

Extrusion Temperature: Room temperature to 260C. Limited by heater power for safety, to prevent thermal decomposition of polymers. The heater is rated for higher temperatures. Email if you have further questions.

How much power does it take to run?

The kits run on an auto-adjusting 110v-240v power supply. The output of the power supply is 12vdc. 110-240VAC, 50/60Hz, 60 watts peak, 50 watts average. This results in a typical cost of 10 cents of electricity for each kg of filament produced.

Can I use the Filastruder to recycle old prints?

While recycling can be challenging with the Filastruder, it can be done! It just takes some creativity and time. Our friend, Stefan over at @CNC_Kitchen created some hacks:
