"This is a PhD research project in Physics. Additively manufactured ('3D printed') metal parts can require significant post-build finishing effort to remove the necessary supports and clean up any remaining marks. This craft based process requires a fair degree of skill and is a source of manufacturing variation, which is incompatible with medical and aerospace applications. This PhD will examine the use of laser processes to perform automated post-build finishing of AM parts. Building on work undertaken within the High Power Laser Applications research group in laser ablation and polishing, topics will include: approaches to support removal & support surface clean up; the best laser(s) for the work; laser beam delivery and positioning machine configuration; design rules for supports to facilitate automated clean up.This project is supported by Renishaw plc, a major UK manufacturing company whose product range includes 'powder bed' additive manufacturing machines, which "3D print" parts by the so-called Selective Laser Melting (SLM) process. The project will link closely to the company, and it is expected that the student will spend short periods working at one or more of Remishaw's sites."

“这是一个物理学博士研究项目。增材制造（“3D打印”）的金属部件可能需要大量的后期加工工作，以移除必要的支撑件并清理任何剩余的痕迹。这种基于工艺的过程需要相当程度的技能，并且是制造变化的来源，这与医疗和航空航天应用不兼容。该博士将研究使用激光工艺来执行AM部件的自动化后处理。基于高功率激光应用研究小组在激光烧蚀和抛光方面所做的工作，主题将包括：支持去除和支持表面清洁的方法;最佳激光器;激光束传输和定位机器配置;支持自动清理的设计规则。该项目由雷尼绍公司提供支持，一家主要的英国制造公司，其产品范围包括“粉末床”增材制造机器，该机器通过所谓的选择性激光熔化（SLM）工艺“3D打印”零件。该项目将与公司紧密联系，预计学生将在Remishaw的一个或多个地点短期工作。"
