Abstract

The selective laser sintering (SLS) was used to prepare components from modified polyamide (PA) powder. The behaviour of the sintering process was analyzed. The influences of the fill laser power, powder bed temperature and powder thickness were discussed in detail. By means of SEM, the morphology and the heat influence were analyzed. Results show that the powders were fused thoroughly which allowed a more dense structure to be built at a powder bed temperature of 98°C, fill laser power 12W, slice thickness of 0.10 mm and a default scanning speed of 1700 mm/s.
