Flame-Retardant and Tensile Properties of Polyamide 12 Processed by Selective Laser Sintering

Composite materials are becoming widely applied in fire-critical conditions such as, e.g., aviation interior parts. Environmental considerations motivate the use of additive manufacturing due to decrease polymer wastes, and therefore additional fuel sources. The aim this work was evaluate effect printing direction on flame retardancy tensile properties 3D-printed test samples polyamide 12 manufactured by selective laser sintering. effects parameters flammability were investigated using vertical burn tests with varied specimen thicknesses directions. It found that these substantial for at a low thickness samples. No significant revealed characteristics 12.
