Characterizing Powder Metal for 3D Printing: Particulate Contamination

Post by:

This article is Part 2 of a series on Powdered Metal Manufacturing Characteristics for 3D Printing written by Stephen Kennedy, Ph.D. of RJ Lee Group. Additive manufacturing, also known as 3D printing, is quickly becoming an industry standard for product manufacturing in a variety of applications, including medical devices, aviation and aeronautics parts, and transportation.

Characteristics of Powder Metal for 3D Printing

Post by:

In Powder Metal (PM) applications such as 3D printing, the flow and packing behavior of PM is influenced by particle size and shape distributions. These properties can be measured in a statistically meaningful way using computer controlled scanning electron microscopy (CCSEM). In livetime, the SEM program detects a particle, defines its perimeter, calculates its size and […]

Supporting Superalloys – A Unique Approach to Powder Metal Cleanliness

Post by:

Superalloys are nickel-based or cobalt-based alloys that are resistant to high temperatures, perform better, are corrosion and oxidation resistant, and last longer than other metals. Superalloy parts are traditionally produced from powdered metals (PM) using subtractive manufacturing techniques. These parts are most often used in heavy industry or in areas having a corrosive environment, as […]

By Crystal Morrison, Ph.D. The additive manufacturing community is abuzz with discussions of what the future will look like—for aerospace, for medicine, and for countless other fields. Those who approach additive manufacturing (AM) from a material science perspective are also considering what these advances mean at the material level—how will a polymer or plastic that […]

If additive manufacturing (AM) has not made its way onto your “topics to watch” list, it soon should. Unlike traditional subtractive forms of manufacturing (e.g., casting, machining) that have gone through decades of regulatory fine-tuning, additive manufacturing is still in its infancy when it comes to standard development and regulatory requirements. AM describes various production […]
