Zusammenfassung:	The present invention provides a method for preparing a high molecular polymer powder material comprising the following steps: adding 20 parts of a high molecular powder material and 0.1 to 10 parts of carbon black into a mixing tank, and performing high-speed stirring for the first time to obtain a high molecular carbon black mixed powder material; adding the high molecular carbon black mixed powder material, 0.1 to 1 part of a flow aid, and 80 parts of a polymer powder material into the powder mixing tank; and performing high-speed stirring for a second time followed by sieving to obtain the high molecular polymer powder material. The high-speed stirring technique of the present invention is adopted to evenly adhere carbon black to the surface of the powder, such that the polymer powder material of the prior art is suitable for fiber laser sintering. The product has excellent surface quality, a finer structure, and optimal overall performance, thereby expanding the types and applications of fiber laser sintered materials.
