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

-从金属中制作精密零件的原型非常昂贵，后处理会大大延迟交货时间。-迭代设计增加了成本和时间。这方面的一个例子是在欧洲核子研究中心超导磁体部门研究小组中使用的金属成型机。在设计最终确定之前，每个磁铁可能需要多个原型机。o使用选择性激光烧结（SLS）技术从不锈钢中制造出这些成型材料，然后需要进行大量的后处理。这包括机械加工，表面处理，然后将较小的子部件连接（激光焊接）以生产完整的部件。-混合制造结合了减法和增材制造，减少了后处理并允许对先前制造的零件进行修改。-使用直接激光沉积（DLD）系统可以减少原材料使用，机器成本，并允许与减法制造工艺集成。-这项技术可以简化和减少成本和时间迭代的精密零件的原型从金属。-本研究建议研究金属混合快速成型方法；结合增、减两种制造方法，减少精密零件的制造时间和生产成本。-紧密耦合（混合）制造还可以提供额外的设计自由度，这是单独通过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.
