Fil X Wayless PLA is a 3D filament that is used where lightweight 3D printing material is required for structural applications within the limitations of PLA polymer. A typical application would be hobbyist airplane, race car, wind turbine, and boat parts. This filament has been made with PLA polymer, color pigment, and a special foaming additive. The environmental impact of using this filament is smaller than most petroleum-based polymers due to the biodegradability of our PLA grade, and the harmless inert gas generated by the foaming process
