摘要	针对现有选择性激光烧结机型号CX-B200 的成型原理，提出在成型腔四周壁贴置加热片的方案，旨在通过加热四周侧壁使热量传至内部粉末，达到改善成型腔内部温度场的目的。现有激光烧结机所使用的材料主要为尼龙、PES等，但对于高温材料如PEEK（聚醚醚酮）无法进行较好的烧结打印，所以从高温加热角度考虑选择加热温度范围为400℃左右的加热片，通过调研分析加热片选择类型为铝加热片或陶瓷加热片。从优化成本角度考虑，尺寸为100mm×100mm×20mm的加热片使用较为普遍。
Abstract	According to the forming principle of the existing selective laser sintering machine model CX-B200, a scheme of pasting heating plates on the surrounding wall of the forming cavity was proposed to improve the temperature field inside the forming cavity by heating the surrounding wall to transfer heat to the internal powder. The materials used in the existing laser sintering machine are mainly nylon, PES, etc., but for high temperature materials such as PEEK (polyether ether ketone) can not be better sintered printing, so from the high temperature heating point of view to choose the heating temperature range of 400℃ or so heating sheet, through research and analysis of heating sheet type is aluminum heating sheet or ceramic heating sheet. From the perspective of optimization cost, the size of 100mm×100mm×20mm heating sheet is more common.
