It is not sustainable and its smoke can be dangerous if inhaled. The reason to prefer this filament to PLA is mainly because of its precision and mechanical specs. ABS (for plastic) stands for Acrylonitrile Butadiene Styrene and it is a thermoplastic which is widely used in everyday objects. It can be printed with any FFF 3D printer which can get to high temperatures as it must be extruded in a range between 220° and 245°, so it’s compatible with all versions of the FABtotum Personal fabricator.",
