Polymer laser sintering is an elaborate additive manufacturing technique because it is subject to process parameters and material properties. In this regard, each polymeric material necessitates a different set of process conditions. To this end, testing was done to determine the most suitable process parameters for a new commercially available polymer (Laser PP CP 60), from Diamond Plastics GmbH. It was established that the material requires slightly different settings from those provided by the supplier for the values for the removal chamber temperature, building chamber temperatures, and laser power to achieve the best mechanical properties (ultimate tensile strength). The preliminary testing indicates that the process parameters that yielded the best mechanical properties for the laser PP CP 60 powder were 125°C, 125°C, 0.15 mm, 250 μm, 4500 mm/s, 34.7 W, 1500 mm/s, and 21.3 W for the removal chamber temperature, building chamber temperature layer thickness, hatch distance, scanning speed fill, laser power fill, scanning speed contour, and laser power contour, respectively.

为确定新型聚丙烯聚合物材料的聚合物激光烧结的最佳工艺参数而进行的初步测试

聚合物激光烧结是一种精细的增材制造技术，因为它受制于工艺参数和材料特性的影响。在这方面，每种聚合物材料都需要一套不同的工艺条件。为此，进行了测试以确定对于来自Diamond Plastics GmbH的新型可商购获得的聚合物（Laser PP CP 60）最合适的工艺参数。已经确定，该材料需要与供应商提供的设置略有不同的设置，以达到去除室温度，建筑室温度和激光功率的值，以实现最佳的机械性能（最终拉伸强度）。初步测试表明，对激光PP CP 60粉末产生最佳机械性能的工艺参数为125°C，125°C，0.15 mm，250 μ米4500毫米/秒，34.7 W，1500毫米/ S，和21.3 W代表去除腔室温度，构建腔温度层厚度，舱口距离，扫描速度填充，激光功率填充，扫描速度轮廓，和激光功率轮廓， 分别。
