CRP Technology launches Windform FR2, a flame-retardant, glass-fiber reinforced material for selective laser sintering (SLS) 3D printing. Windform FR2 is halogen-free polyamide-based material, which combines wear and temperature resistance.
Windform FR2 differs from Windform FR1 on its reinforcement material: Windform FR2 is glass-fiber reinforced, Windform FR1 is carbon-fiber reinforced); color (Windform FR2 is off-white, Windform FR1 is dark gray); electrical behavior (Windform FR2 is electrically insulating), and has smoother surface finish for good detail resolution.
Windform FR2 passed successfully the FAR 25.853 12-second vertical and 15-second horizontal flammability tests as well as the 45° Bunsen burner test and smoke density test.
