A metal/polymer hybrid featuring nanotechnology aimed at extremely lightweight components was introduced at K 2007 today by DuPont Engineering Polymers and partners Morph Technologies of Toronto, Canada; Integran Technologies, of Pittsburgh, PA; and PowderMetal Technologies of Carlsbad, CA. Key to the technology is a new proprietary process called MetalFuse that applies precise amounts of nanometal to molded plastic components. Parts are said to have the stiffness of aluminum or magnesium but with better strength. Grain sizes of the metals are 1000 times smaller than conventional metals. “Nanocrystalline nickel or nickel-iron are high-performance metals that are two to three times stronger than normal steel and are also significantly harder, with better wear and friction performance,” says Gino Palumbo, president of Integran Tehcnologies. Initial development will focus on selected applications in the automotive, consumer electronics, and sporting goods markets.
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.
