Refil – 3D printing with recycled plastics

There’s a new filament brand in town: Refil. Their filaments are made from recycled plastics. At the moment they offer black ABS (from recycled car dashboards) and PET (from recycled drinks bottles), with more colors and materials to follow soon. When we attended a presentation by one of the founders, he gave us samples of both filament types and we were eager to see if this stuff was any good.

One of the main problems in any recycling project is that the source material is usually full of contaminants, additives and impurities. Refil appears to have solved this problem, using a combination of pickiness (only using RoHS/REACH-compliant source materials) and technology (working with industry partners from the recycling and processing areas). The result are filaments that look very good “on the roll”, indistinguishable from virgin material. Because the filament is made on very high-quality, industrial extruders, filament roundness and diameter is as constant as that of any other commercially produced filament. In keeping with the recycling philosophy, the spools are made of recycled cardboard, which is a nice touch.
