Modelling and validation of Selective Laser sintering of PA12
15th World Congress on Computational Mechanics (WCCM-XV) and 8th Asian Pacific Congress on Computational Mechanics (APCOM-VIII), 2022 One of the larger growing fields within additive manufacturing is the selective laser sintering process of semi-crystalline polymer powders. The powder is locally fused at certain areas, due to the energy output of a laser. This method allows for rapid production of complex parts, which are well suited for prototyping.
