The document describes a new triboPA filament material for 3D printers that contains molybdenum bisulfide for high friction and abrasion resistance. It has a coefficient of friction of 0.30-0.28 and properties including tensile strength of 75 MPa, elongation of 40%, and flexural modulus of 2800 MPa. Printing parameters are listed for FFF printers using a 0.5mm nozzle at 260C with a 180-190C heated bed. Images show the material can be printed and milled with no warping.
