A finite element model considering volume shrinkage with powder-to-dense process of powder layer in selective laser melting (SLM) is established. Comparison between models that consider and do not consider volume shrinkage or powder-to-dense process is carried out. Further. parametric analysis of laser power and scan speed is conducted and the reliability of linear energy density as a... https://halohealthcarers.shop/product-category/diffusers-salt-lamps/
