Laser powder bed fusion (PBF) is an emerging manufacturing approach to produce net shapesand functional products directly from computer aided three dimensional designs. The parts arebuilt by the consecutive application and consolidation of material layers. In order to becomemore widely accepted within manufacturing, there are still considerable hardware associatedissues which need to be resolved including but not restricted to; residual stress, surfacetexture and methodologies for surface finishing, these problems are exacerbated as theprocess gets faster and is applied to larger parts. The ability to capture in -- process data bydigital integration will further validate the acceptance of the AM process in the production ofparts which are controlled by regulatory standards, where process records are required.The aim of this project is to produce a metal AM machine platform, the subsystems of which arescalable in future to meter class, which is capable of reducing the residual stresses developedduring the AM build, and that will perform in process non-contact finishing on parts as they arebuilt. Multiple machines will also be digitally connected and monitored via sensors for real-timeinsights across a cohort of globally connected manufacturing facilities.

激光粉末床熔合（PBF）是一种利用计算机辅助三维设计直接制造出具有净形和功能性产品的新兴制造方法。这些零件是通过材料层的连续应用和固结而制成的。为了在制造业中更广泛地接受，仍然有相当多的硬件相关的问题需要解决，包括但不限于：残余应力，表面纹理和表面精加工方法，这些问题随着工艺变得更快并应用于更大的部件而加剧。通过数字集成捕获过程数据的能力将进一步验证AM工艺在受监管标准控制的零件生产中的可接受性，其中需要过程记录。该项目的目的是生产金属AM机器平台，其子系统将来可扩展到米级，能够减少AM构建期间产生的残余应力，并将在制造过程中对零件进行非接触式精加工。多台机器也将通过传感器进行数字连接和监控，以便在全球连接的制造设施中进行实时洞察。
