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.

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 Additive Manufacturing of Metals: The Technolog...

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 Ti-6Al-4V is extensively used in aerospace for its

Requires extensive post-processing (support removal, heat treatment) Rapid prototyping and on-demand manufacturing Limited library of printable "certified" alloys Improved energy efficiency and lower carbon footprint Potential for metallurgical defects like porosity Industry Expert Perspectives It is widely recognized for its ability to

“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

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

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
