Additive Manufacturing Of Metals: The Technolog... Guide

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

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...

Similar to SLM but uses an electron beam in a vacuum. It offers higher build rates but generally results in a rougher surface finish. Most metal AM processes involve selectively melting or

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. Core Technologies Similar to SLM but uses an

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

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.
