阅读说明：本技术 基于粉末的增材制造法 (Powder-based additive manufacturing method ) 是由 D.阿克滕 T.比斯根 M.凯斯勒 P.赖歇特 B.梅特曼 于 2018-12-13 设计创作，主要内容包括：增材制造法(3D-打印)使用具有可熔聚合物的颗粒。所述可熔聚合物包含热塑性聚氨酯聚合物,其具有160至270℃的熔融范围(DSC,差示扫描量热法；以5K/min的加热速率进行的第二次加热)和50或更高的根据DIN ISO 7619-1的肖氏D硬度,并且其具有在温度T下5至15 cm/10 min的根据ISO 1133的熔体体积速率(melt volume rate(MVR))和大于或等于90 cm3/10 min的在将该温度T提高20℃时的MVR变化。借助于该方法可得到的物体。(Additive manufacturing processes (3D-printing) use particles with fusible polymers. The fusible polymer comprises a thermoplastic polyurethane polymer having a melting range (DSC, differential scanning calorimetry; second heating at a heating rate of 5K/min) of 160 to 270 ℃ and a shore D hardness according to DIN ISO 7619-1 of 50 or more, and having a Melt Volume Rate (MVR) according to ISO 1133 of 5 to 15 cm/10 min at a temperature T and a MVR change at increasing the temperature T by 20 ℃ of greater than or equal to 90 cm fraction/10 min. An object obtainable by means of the method.)
