Study on Performance of Metal and Polymer Composites Parts Based by Additive Manufacturing

Aiming at the current SLS forming metal parts with poor performance, low accuracy, and cannot be directly used, etc., in this paper, Having studied a formula of SLS forming material with good formability, simple preparation and low cost for laser sintering. Using the orthogonal cut-and-try method to study and optimize the influence of SLS forming craft parameter on the shape semi-finished product intensity and the precision. By analyzing the high temperature sintering process of the degraded billet, the high temperature sintering process of the composite metal powder material was established. Having studied The mechanical strength of metal parts after the post-treatment process such as degreasing and high-temperature sintering, as well as its internal microscopic organization appearance characteristic, obtain the compared effect.
