Titanium parts are produced by the “Solvent on granules 3D-Printing” technique (SG-3DP). Angular Titanium Hydride powders are used. A special purpose table-top machine, designed and built in a previous development, is used to print green parts, which are subsequently debinded, dehydrided and sintered in a muffle furnace. Porous electrode plates are produced with and without hole grids. The parts exhibit good shape preservation, with open interconnected porosities between 55 and 59%. The microstructure is characterized by optical metallography and scanning electron microscopy. In addition, experimental watch cases have been successfully printed and sintered. The results show the feasibility of using hydride powder for 3D-Printing of complex parts with good shape preservation.

通过溶剂喷射在颗粒床上从氢化钛粉末中进行钛零件的3D打印
钛零件是通过“颗粒上的溶剂3D打印”技术(SG-3DP)生产的。使用角状氢化钛粉末。在以前的开发中设计和制造的专用台式机器用于印刷未加工的零件,随后将其进行脱胶,脱水和烧结在马弗炉中。产生具有和不具有孔栅的多孔电极板。零件具有良好的形状保持性,开放的互连孔隙率在55%至59%之间。显微组织通过光学金相和扫描电子显微镜表征。此外,实验表壳已成功印刷和烧结。结果表明,使用氢化物粉末进行3D打印复杂零件并保持良好形状的可行性。
