Additive Manufacturing Of Metals: The Technolog... May 2026

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 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.

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 Most metal AM processes involve selectively melting or

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 Parts may suffer from defects such as anisotropy,

Experts highlight that the value of metal AM is highly dependent on production volume and application complexity.
