Opel is in the news almost weekly for financial reasons. But the German-based subsidiary of General Motors is also making some technical news. Opel joined with Recaro, a Tier II seat maker, and BASF to develop an all plastic car seat that eliminates the requirement for a steel frame.
The seats are low weight while offering high mechanical strength, good ergonomic properties and a sporty look. The seat pan is made of Ultramid B3ZG8, a very tough yet stiff PA6. Ultramid B3G10 SI is used in the large, free-standing backrest shell as well as in the crossbar. The insert for the backrest shell is made of Neopolen P 9225 K (EPP), an energy-absorbing foam that also covers edges and serves as a module carrier for motors and seat components such as the spinal column support.
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.
