Ceramic chopper based on 3D printing and processing method thereof
The invention belongs to the technical field of ceramic riving knives and additive manufacturing 3D printing, and particularly relates to a ceramic riving knife based on 3D printing and a machining method thereof.The ceramic riving knife is manufactured by conducting selective laser sintering on a ceramic riving knife blank body obtained after 3D forming, and the ceramic riving knife blank body comprises raw materials, the invention discloses a photosensitive ceramic coating which comprises the following components in parts by weight: 100 parts of ceramic powder, 5-15 parts of photosensitive resin cyclotrimethylolpropane methylal acrylate, 0.5-1 part of a photoinitiator selected from (2, 4, 6-trimethylbenzoyl) diphenyl phosphine oxide and 3-5 parts of a binder polycarboxylate zinc cement. According to the technological method of the ceramic chopper based on 3D printing, a selective laser sintering method is adopted, and the ceramic chopper is prepared by mainly utilizing a powder ceramic material to be subjected to photocuring forming and then performing high-temperature sintering under the irradiation of green laser.
本发明属于陶瓷劈刀及增材制造3D打印技术领域，具体涉及一种基于3D打印的陶瓷劈刀及其加工方法，该陶瓷劈刀由3D成型后的陶瓷劈刀胚体通过激光选择性烧结而制得，该陶瓷劈刀胚体包括原料：按质量份数计，陶瓷粉末100份、感光树脂环三羟甲基丙烷甲缩醛丙烯酸酯5～15份、光引发剂选自(2,4,6‑三甲基苯甲酰基)二苯基氧化膦0.5～1份、粘结剂聚羧酸锌水门汀3～5份。本发明开发出一种基于3D打印的陶瓷劈刀的工艺方法，通过采用选择性激光烧结法，主要是利用粉末陶瓷材料先进行光固化成型后，再在绿光激光照射下进行高温烧结而制得陶瓷劈刀。
