Optimized laser and electron beam based additive manufacturing of advanced intermetallic components

增材制造（AM）或3D打印正在迅速发展成为一种颠覆性的制造技术，能够实现前所未有的大规模定制。从物体的数字渲染开始，用各种各样的材料“打印”出任意复杂的几何部件，这种能力正在推动许多行业的快速创新。就结构部件而言，增材制造允许更少的加工步骤，更复杂的几何形状和更轻的重量，适用于从医疗到航空航天工业的关键应用。然而，由于所涉及的过程的复杂性，这种技术的能力目前受到限制。**该提案是在“加拿大-德国2 +2先进制造-工业4.0联合呼吁”的框架内提出的，合作伙伴包括一家专门从事过程模拟的加拿大公司（融合制造技术）、一家专门制造先进涡轮增压器的德国公司（G+L Innotech）和德国航空航天中心DLR。该项目的目标是通过对先进金属间材料的现场监测和基于耦合物理的过程模拟来开发工艺优化技术，并通过激光和电子束增材制造技术将这些知识用于增材制造涡轮增压器的构建。* * * *

Additive manufacturing (AM), or 3D printing, is rapidly being developed as a disruptive manufacturing technology capable of unprecedented mass customization. The ability to start from a digital rendering of an object and to 'print' an arbitrarily complex geometric part from a wide variety of materials is driving rapid innovation in a number of industries. In the case of structural components, additive manufacturing is allowing for fewer processing steps, more complex geometry and lighter weight for crucial applications ranging from the medical to the aerospace industries. The capabilities of this technique are, however, limited at present by the complexity of the processes involved. **This proposal is being made within the framework of the 'Joint Canada-Germany 2 +2 call on Advanced Manufacturing-Industry 4.0' in collaboration with a Canadian company with speciality in process simulation (Convergent Manufacturing Technologies), a German company with specialization in the manufacture of advanced turbochargers (G+L Innotech) and the German aerospace centre, DLR. The aims of the project are to develop technologies for process optimization via in-situ monitoring of advanced intermetallic materials with coupled physics-based process simulation and to use this knowledge for the construction of additively manufactured turbochargers by means of both laser and electron beam-based AM technologies. ****
