ExtrudeX on Kickstarter: DIY extruder aims to turn 3D printing waste into new filament

ExtrudeX, a desktop filament extruder designed to reuse 3D printing waste, has been launched on Kickstarter. Creative3D is behind the project. The aim is to provide an affordable option for re-extrusion, as low entry-level prices are rare in this segment, while existing systems can cost well over $10,000, according to the description.

ExtrudeX is designed as a 3D-printable kit. Supporters receive STL files and assembly instructions. The most expensive Kickstarter option is $59. However, additional parts such as a motor, heating elements, bearings, and electronics are required for assembly. Creative3D estimates the cost of non-printable components to be typically between $180 and $250. This brings the total price to under $300, not including your own labor.

The concept relies on shredded printing material, such as misprints, support structures, or purge blocks. In addition, the campaign plans to mix in new material to mitigate a key problem: molecular degradation caused by remelting and extrusion. As a guideline, the project specifies around 60 percent fresh pellets and 40 percent shredded waste, both from the same material. In practice, this creates a demand for pellets that can limit the proportion of recycled material. In addition, the system requires pre-shredding, which is not included in the kit.

Technically, Creative3D describes a screw drive with a DC gear motor in a heated metal tube, controlled by a simple temperature controller. The material leaves a nozzle as a 1.7 mm strand and runs through a short cooling section with a 12 V fan. A puller is designed to pull the strand at a constant speed. For diameter testing, the campaign lists optional measurement solutions, such as an additional display unit; at the same time, there is no clearly integrated winding system, so spool management must be solved independently.

Further hurdles lie in material consistency. Waste varies in terms of polymer, brand, and color additives, which may require sorting and new printing parameters. Filament quality remains critical because uneven diameters lead to printing errors and require continuous attention during production. Creative3D also offers a commercial license that allows buyers to manufacture and resell ExtrudeX units.
