Investigators at Pennsylvania State University Target Alloys (Printability of alloys for additive manufacturing)

Science Letter |

By a News Reporter-Staff News Editor at Science Letter -- New research on Alloys is the subject of a report. According to news reporting out of University Park, Pennsylvania, by NewsRx editors, research stated, "Although additive manufacturing (AM), or three dimensional (3D) printing, provides significant advantages over existing manufacturing techniques, metallic parts produced by AM are susceptible to distortion, lack of fusion defects and compositional changes. Here we show that the printability, or the ability of an alloy to avoid these defects, can be examined by developing and testing appropriate theories."

Our news journalists obtained a quote from the research from Pennsylvania State University, "A theoretical scaling analysis is used to test vulnerability of various alloys to thermal distortion. A theoretical kinetic model is used to examine predisposition of different alloys to AM induced compositional changes. A well-tested numerical heat transfer and fluid flow model is used to compare susceptibilities of various alloys to lack of fusion defects. These results are tested and validated with independent experimental data."

According to the news editors, the research concluded: "The findings presented in this paper are aimed at achieving distortion free, compositionally sound and well bonded metallic parts."
