I appreciate the healthcare-specific testing performed on the separate product lines. Good design control is an absolute must during the development of medical devices and this type of specific testing helps designers quickly and accurately document compliance to FDA regulations.
Researchers have been working on a number of alternative chemistries to lithium-ion for next-gen batteries, silicon-air among them. However, while the technology has been viewed as promising and cost-effective, to date researchers haven’t managed to develop a battery of this chemistry with a viable running time -- until now.
Norway-based additive manufacturing company Norsk Titanium is building what it says is the first industrial-scale 3D printing plant in the world for making aerospace-grade metal components. The New York state plant will produce 400 metric tons each year of aerospace-grade, structural titanium parts.
