There’s a “real horse race” at General Motors between new magnesium alloys and carbon-fiber reinforced plastics for use in load-bearing structural applications of future car platforms. That comment was made in an exclusive Design News interview today with Mark Verbrugge, the director of GM’s materials and process lab. For the moment, magnesium is leading because of the successful use of a new Norsk Hydro magnesium alloy in the engine cradle of the Corvette Z06, The cradle provides a 35 percent weight savings over the previous aluminum structure. “There are only about 10 pounds of magnesium in a car now,” says Verbrugge. “There’s a lot of bandwidth there for magnesium to go after.”
A composite based on a high-performance PEEK-like resin we told you about two years ago when it was still in R&D has now been licensed by the US Naval Research Laboratory (NRL) for commercial manufacturing.
Microsoft, HP, Dassault, and other industry heavyweights in 3D printing have launched a new 3DP file format, 3MF. The consortium says the spec will more fully describe a 3D model and will be interoperable with multiple applications, platforms, services, and printers.
NASA's been working on several different ongoing projects for 3D-printed rocket engine components in metals and now it's reached another first in aerospace 3D printing: a full-scale, 3D-printed rocket engine component made of copper.
