Residual stress analysis in residual stresses in fine scale (sub mm) lattice structures manufactured by the metal additive manufacturing (

The overall aim of this study is to understand the influence of laser scan strategy, specimen thickness and geometric constraint on the generation of residual stresses in fine scale (sub mm) lattice structures manufactured by the additive manufacturing (AM) process Laser beam powder bed fusion (PBF-LB) with a view for application in medical implant devices.

本研究的总体目标是探究激光扫描策略、试样厚度及几何约束对采用激光束粉末床熔融（PBF-LB）增材制造（AM）工艺制备的亚毫米级精细尺度点阵结构中残余应力生成的影响，以期将该研究成果应用于医用植入器械领域。
