Abstract—An apparatus for selective laser sintering of micron and submicron fraction powders is described. The apparatus allows studies with small volumes of polymer powders, as well as aqueous and alcoholic suspensions to refine the sintering process in order to achieve high spatial resolution (on the order of 10 μm). Thin (approximately 20 μm) layers of spherical microparticles of polymethylmethacrylate (PMMA) with an average diameter of 0.5 to 3 μm were formed. Optimization of the parameters of selective laser sintering and stepwise formation of single layers of PMMA allowed us to obtain 3D structures with a resolution of less than 100 μm.

一种用于高空间分辨率粉末材料选择性激光烧结工艺研究的装置

摘要—描述了一种选择性激光烧结微米和亚微米级粉末的设备。该设备允许使用少量的聚合物粉末以及水性和含酒精的悬浮液进行研究，以完善烧结工艺，从而获得较高的空间分辨率（约10μm）。形成平均直径为0.5至3μm的聚甲基丙烯酸甲酯（PMMA）球形微粒的薄层（约20μm）。优化选择性激光烧结的参数并逐步形成PMMA单层，使我们能够获得分辨率小于100μm的3D结构。
