Additive Manufacturing Of Metals: — The Technolog...

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.

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. Additive Manufacturing of Metals: The Technolog...

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

“AM transforms more and more from rapid prototyping to rapid manufacturing applications which require not only profound knowledge of the process itself, but also of the microstructure” ScienceDirect.com · 9 years ago Future Outlook Nickel-based superalloys like Inconel 718 are favored for

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, 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.
