Abstract

Through selective laser sintering PSB powers, the influence of temperature control in SLS process on precision of sinter products was studied by orthogonal experiments and variance analysis means. The results show that the influence of pre-heating temperature of differ process on precision of products is different. The influence of pre-heat temperature before sintering first layer on warping degree is bigger, and the influence of beforehand warm temperature before sintering last layer on difference size between sample two end is bigger. The better curve of temperature control is first temperature of pre-heat phase(TA)is 85,and pre-heat temperature before sintering first layer (TB)is 105,and pre-heat temperature before sintering last layer (TC)is 85.
