The project is focused on the optimization of laser powder bed metal fusion processing and post-processing of**highly-spherical plasma-atomized titanium alloy (Ti64) powders. More specifically, the powder spreading and**printing parameters will be optimized to significantly improve the process productivity. This productivity**increase will be obtained without affecting the mechanical and geometrical characteristics of the printed**product. (Our focus on productivity is justified by the fact that this aspect represents one of the main limitations**of the LPBF technology.)**The deliverables of the project are: a) the optimized parameters of laser powder bed fusion and post-processing**of Ti64 components and their mechanical and geometric characteristics; c) direct costs of LPBF processing and**post-processing of these components. The results obtained will be used in the rapidly growing sector of**additive manufacturing.

该项目的重点是优化激光粉末床金属熔融加工和后处理 ** 高球形等离子体雾化钛合金（Ti64）粉末。更具体地说，将优化粉末散布和 ** 打印参数，以显著提高工艺生产率。这种生产率 ** 的提高将在不影响印刷 ** 产品的机械和几何特性的情况下获得。(Our对生产率的关注是合理的，因为这方面是LPBF技术的主要限制之一。）**该项目的交付成果是：a）钛64部件的激光粉末床熔合和后处理 ** 的优化参数及其机械和几何特性; c）这些部件的激光粉末床熔合处理和后处理 ** 的直接成本。所获得的结果将用于快速增长的 ** 增材制造领域。
