Metal additive manufacturing (AM) creates complex 3D components at near net shape. Surface finish(SF) of theAM part is uneven, with surface roughness being variable over the facets of the design. The surface qualityachievable using standard post-processing methods is unacceptable for some industry sector AM part uptake.The challenge here is to improve metal AM part surface finish by decreasing the variability of surface roughnessof the near net-part during AM production and to improve post-processing (PP) techniques to suit increasedAM part complexity. This project aims to develop an innovative process optimisation system which can link AMbuild parameters to the surface finish produced to generate a software tool for AM designers to use to selectthe best parameters to generate an optimised surface finish for the individual AM part, and subsequentoptimised post-processing SF methodologies. This approach will optimise both the AM build process as well asPP techniques to enable the delivery of the required surface finishes, increase industrial adoption of high-valueAM parts, generating increased sales and employment while supporting UK manufacturing innovation.

金属增材制造（AM）以近净形创建复杂的3D部件。AM部件的表面光洁度（SF）是不均匀的，表面粗糙度在设计的小平面上是可变的。使用标准后处理方法可实现的表面质量对于某些工业部门的增材制造零件来说是不可接受的。这里的挑战是通过减少增材制造生产过程中近净零件表面粗糙度的变化来提高金属增材制造零件的表面光洁度，并改进后处理（PP）技术以适应增材制造零件的复杂性。该项目旨在开发一种创新的工艺优化系统，该系统可以将AM构建参数与所产生的表面光洁度相关联，以生成一种软件工具，供AM设计人员用于选择最佳参数，从而为单个AM部件生成优化的表面光洁度，并遵循优化的后处理SF方法。这种方法将优化AM构建过程以及PP技术，以实现所需的表面光洁度的交付，增加高价值AM部件的工业采用，增加销售和就业，同时支持英国制造业创新。
