Beschreibung
Zusammenfassung:	The invention relates to pure-color 3D printing nylon powder capable of realizing near-infrared laser absorption sintering and a method for preparing the powder. The method comprises the following steps: firstly, adding nylon resin, an antioxidant, a light absorbent, an optional catalyst and a fluorescent whitening agent into a crystallization kettle taking ethanol as a solvent, and then carrying out heating dissolution, cooling precipitation, centrifugal drying, scattering and screening and the like to obtain the pure-color 3D printing nylon powder capable of realizing near-infrared laser printing. 本发明涉及一种可实现近红外激光吸收烧结的纯色3D打印尼龙粉末，和制备这种粉末的方法。所述的办法包括以下步骤：首先，将尼龙树脂、抗氧剂、光吸收剂、任选的催化剂和荧光增白剂加入到乙醇作为溶剂的结晶釜中，然后经过升温溶解、降温析出、离心干燥、打散筛分等步骤得到一种可实现近红外激光打印的纯色3D打印尼龙粉末。
