# Producing Quality Metal Parts with Additive Manufacturing

Posted by [Larry Somrack](https://blog.nslanalytical.com/author/larry-somrack) on 4/23/20 10:10 AM

The[aerospace industry](https://www.nslanalytical.com/industries/aerospace) is increasingly adopting metal [additive manufacturing](https://www.nslanalytical.com/industries/additive-manufacturing) (AM) for both flight safety-critical aircraft parts and non-critical flight parts. The approach offers a shorter development cycle, which means products can be developed quicker and design changes easily incorporated. Similar to other 3D-printing methods, metal AM, specifically select laser melting (SLM) and electron-beam melting (EBM), builds up a part layer-by-layer by depositing thin layers of metal powder that are melted with a laser or other thermal source.

## The Benefits of Additive Manufacturing

Additive manufacturing can be used for very fast prototyping of parts, short production runs, and as a faster and more economical way to create part molds and fixturing compared to machining. One of its greatest advantages is in making highly intricate parts. In the past, complex parts would require several different machining operations. With metal AM, it is possible to make a single part to replace multiple pieces that would otherwise be combined with welding or fastening systems. This not only makes manufacturing faster, less expensive and more consistent, but it also creates a seamless piece that is stronger and has less opportunity for failure.

## How to Get Started

Producing a quality 3D-printed metal part requires an understanding of the powder properties used to create the part in addition to analyzing the strength and chemistry of the part itself. Partnering with a trusted independent testing laboratory like NSL can provide insight into the entire 3D-printing process, from [powder characterization](https://www.nslanalytical.com/testing/powder-characterization-lab) to determining the best tests to qualify parts for the aerospace industry.

NSL president Larry Somrack and quality assurance manager Cynthia Hagan were featured in Industrial Heating Magazine to discuss the process and benefits producing quality metal parts with additive manufacturing.
