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

加法制造(AM)或3D打印正在迅速发展，成为一种能够进行前所未有的大规模定制的颠覆性制造技术。从物体的数字渲染开始，并从各种材料中打印出任意复杂的几何部件的能力正在推动许多行业的快速创新。就结构部件而言，对于从医疗到航空航天工业的关键应用，添加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。然而，目前这项技术的能力受到所涉及过程的复杂性的限制。这项建议是在“加拿大-德国2+2联合呼吁先进制造业-工业4.0”的框架内提出的，合作伙伴包括一家专门从事过程模拟(融合制造技术)的加拿大公司、一家专门制造先进涡轮增压机的德国公司(G+L Innotech)和德国航空航天中心德国航天中心。该项目的目标是通过对先进金属间化合物材料的现场监测和基于物理的工艺模拟来开发工艺优化技术，并将这些知识用于通过激光和电子束AM技术建造附加制造的涡轮增压器。

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.
