Most metal AM processes involve selectively melting or joining metal feedstocks, typically in powder or wire form. The three most industrially relevant technologies include:
Requires extensive post-processing (support removal, heat treatment) Rapid prototyping and on-demand manufacturing Limited library of printable "certified" alloys Improved energy efficiency and lower carbon footprint Potential for metallurgical defects like porosity Industry Expert Perspectives Additive Manufacturing of Metals: The Technolog...
Similar to SLM but uses an electron beam in a vacuum. It offers higher build rates but generally results in a rougher surface finish. Most metal AM processes involve selectively melting or
Ti-6Al-4V is extensively used in aerospace for its strength-to-weight ratio. Nickel-based superalloys like Inconel 718 are favored for high-temperature energy and aerospace applications. Additive Manufacturing of Metals: The Technolog...
