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.

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.
