To offer a specific example, one of the most pressing questions regarding metal 3D printing concerns the reusability of metal powders. How many times can metal powder be re-fed into a printer before its properties undergo a substantial change? Answering this question requires significant data collection, which would explain why some companies are incorporating in-process inspection into industrial 3D printers.
Of course, not every printer will be amenable to in-process inspection techniques. In such cases, manufacturers utilizing metal 3D printing will need to rely on metallurgical laboratories to verify the integrity of re-used powders. Fortunately, many such labs are starting to add metal powder characterization to their repertoire.
For example, NSL Analytical Services, Inc. recently announced that it is offering chemical composition, powder characterization and metallurgical evaluation for additive manufacturing applications in the medical, nuclear and aerospace industries.
NSL’s services for additive manufacturing include verifying feed stock, identifying mechanical and chemical properties and improving the properties of additively manufactured products. The company will be presenting a paper entitled “NiCr-Alloy Powder Re-use and Testing Results in Additive Manufacturing” at the MS&T (Materials Science & Technology) conference in Salt Lake City, Utah.
