Modern AM can process a wide range of engineering materials, including steel, aluminum, titanium, nickel-based superalloys, and even precious metals. However, the rapid heating and cooling cycles inherent to these processes create unique microstructures that differ significantly from traditionally wrought parts.
Similar to SLM but uses an electron beam in a vacuum. It offers higher build rates but generally results in a rougher surface finish.
Experts highlight that the value of metal AM is highly dependent on production volume and application complexity. Additive Manufacturing of Metals: The Technolog...
Metal Additive Manufacturing (AM) has transitioned from a rapid prototyping tool to a sophisticated industrial production method capable of creating complex, high-performance parts. It is widely recognized for its ability to produce intricate geometries that are impossible or too costly for conventional subtractive manufacturing. Core Technologies
Most metal AM processes involve selectively melting or joining metal feedstocks, typically in powder or wire form. The three most industrially relevant technologies include: Modern AM can process a wide range of
Feeds metal powder or wire directly into a heat source to build or repair components. This is frequently used for large-scale parts and remanufacturing applications. Materials and Metallurgy
Uses a high-power laser to selectively melt layers of metal powder. It is known for producing high-precision, dense parts but often requires time-consuming post-processing. It offers higher build rates but generally results
