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.

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.

The field is moving toward to enhance sustainability and further reduce costs. Current research priorities include the development of multi-material printing , real-time process monitoring, and sophisticated computational models to predict and prevent defects during the build process.

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 Modern AM can process a wide range of

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

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. It is known for producing high-precision, dense parts

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
