Title (150 characters) Metal hybrid rapid manufacture for prototyping precision parts

-从金属制作精密零件的原型可能非常昂贵，后处理增加了极大的延迟时间。-迭代设计放大了这一成本和时间。-这方面的一个例子是欧洲核子研究中心超导磁力部研究小组使用的金属成型。o每个磁体在最终设计之前可能需要多个原型成型。o这些成型使用选择性激光烧结(SLS)由不锈钢生产，然后需要大量的后处理。这包括机械加工、表面处理，然后连接(激光焊接)较小的子部件以生产完整的部件。-混合制造结合了减法和加法制造，减少了后处理并允许修改先前制造的部件。-使用直接激光沉积(DLD)系统可以减少原材料使用、机器成本，并允许与减法制造过程集成。-这种技术既可以简化，也可以减少从金属迭代精密部件的原型的成本和时间。-本研究建议研究金属混合快速成型方法；结合加法和减法制造方法，以减少精密零件的制造时间和生产成本。-紧耦合(混合)制造还可以提供额外的设计自由，这是单独使用减法或加法无法实现的。

- Prototyping precision parts from metal can be very expensive and post processingadds a significant delay to lead times.- Iterative designs amplify this cost and time.- An example of this is the generation of metallic formers used in the SuperconductingMagnets Division research team at CERN.o Each magnet may require multiple prototype formers before a design isfinalised.o These formers are produced from stainless steel using Selective LaserSintering (SLS) and then requiring significant post-processing. This includesmachining, surface treatment and then joining (laser welding) of smaller subparts to produce the full part.- Hybrid manufacture combines subtractive and additive manufacturing, reducing postprocessing and allowing the modification of previously manufactured parts.- The use of a Direct Laser Deposition (DLD) system could reduce raw material use,machine cost, and allow integration with a subtractive manufacturing process.- This technique could both simplify and reduce the cost and time to iterate prototypesof precision parts from metal.- This research proposal recommends the investigation of a metal hybrid rapidprototyping methodology; combining both additive and subtractive manufacturingmethods to reduce manufacturing time and production costs of precision parts.- Tightly coupled (hybrid) manufacture may also offer additional design freedoms thatare not possible through subtractive or additive in isolation.
