Abstract Scope |
Laser powder bed fusion (LPBF) additive manufacturing allows for the opportunity to customize parts, manufacture low lot size items, and revolutionize supply chain logistics. One key challenge to the adaptation of LPBF technology is that the process needs to be optimized to achieve consistency between builds and lots. Recoater spreading can affect the topology of the powder bed, which could lead to variability in porosity and surface roughness if the recoater blade is damaged. The present study will investigate the effect of damage to the recoater on the powder bed using the discrete element method (DEM). Intentional notches will be introduced to the recoater to simulate damage. Interactions between the damaged recoater and the topology and spread quality of the powder bed will be investigated. |
