Patent number: 10879039Abstract: A method of charge mitigation in additive layer manufacturing is provided, which uses a charged particle beam (103) to fuse metal powder (122) within a metal powder bed (123) to form a product layer-by-layer, the method comprising using a charged particle beam optical system to form a charged particle beam, to steer the charged particle beam to be incident on a powder bed of metal powder and to scan over the powder bed to fuse powder into a desired layer shape. While steering the charged particle beam, the method comprises using a neutralising particle source (160) to generate neutralising particles of an opposite charge to the charged particles in the vicinity of the charged particle beam such that the neutralising particles are attracted to the charged particles of powder in the powder bed. An additive layer manufacturing apparatus (100) is also provided.Type: GrantFiled: December 15, 2017Date of Patent: December 29, 2020Assignee: RELIANCE PRECISION LIMITEDInventors: Jakob Albert Van Den Berg, Martyn James Hussey, William Thomas Richardson, Ian Laidler
