Parts may suffer from defects such as anisotropy, micro-porosity, gas entrapment, or residual stresses. Advantages and Limitations Extreme design freedom and customization High initial equipment and production costs Significant reduction in material waste and scrap Similar to SLM but uses an electron beam in a vacuum

Most metal AM processes involve selectively melting or joining metal feedstocks, typically in powder or wire form. The three most industrially relevant technologies include: Additive Manufacturing of Metals: The Technolog...
