Researchers at Carnegie Mellon University have designed a rapid screening method for new 3D printing alloys. The method allows users to quickly understand and develop correlations between process variables and alloy composition.
Creating new metal powders for additive manufacturing can be a slow and laborious process. Because despite the countless number of metals and alloys out there, relatively few of these materials possess the right physical properties for being turned into powder and then sintered, melted, or jetted.
Alloy - Printing - Example - Lot - Time
Designing a new alloy for 3D printing, for example, takes a lot of time. Lots of powder—sometimes hundreds of pounds worth—is needed to carry out the requisite tests, and this is no guarantee that the end product will even be printable.
“Even at a research scale, it’s not straightforward or efficient to fabricate small batches of powder for every possible material composition that we need to test,” explained Bryan Webler, assistant professor of materials science and engineering at Carnegie Mellon. “We need computational and experimental approaches to screen compositions to provide some initial guidance before we try to make test batches of powders.”
Problem - Webler - Team - Method - Kind
Faced with this problem, Webler and his team have devised a new rapid screening method that provides the kind of “guidance” needed to develop alloys for 3D printing. They say the method could save engineers lots of time and money in...
