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.

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. Additive Manufacturing of Metals: The Technolog...

“metal 3D printing can be the most affordable way to make parts for a significant slice of low to medium volume production” Markforged

Experts highlight that the value of metal AM is highly dependent on production volume and application complexity. The field is moving toward to enhance sustainability

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

Similar to SLM but uses an electron beam in a vacuum. It offers higher build rates but generally results in a rougher surface finish. However, the rapid heating and cooling cycles inherent

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.
