It’s Only Common Sense: Win the Sale Before the RFQ Arrives
The Marketing Minute: Marketing Is a Team Sport
"We are really studying a very basic science problem, which is what happens to metal when you heat it up with a high-power laser," said Cang Zhao, an Argonne postdoc and the other co-first author of the paper. "Because of our unique experimental capability, we are able to work with our collaborators on experiments that are really valuable to manufacturers."
The research team believes this research could motivate makers of additive manufacturing machines to offer more flexibility when controlling the machines and that the improved use of the machines could lead to a significant improvement in the final product. In addition, if these insights are acted upon, the process for 3D printing could get faster.
"It's important because 3D printing in general is rather slow," Rollett said. "It takes hours to print a part that is a few inches high. That's OK if you can afford to pay for the technique, but we need to do better."
