Design engineers are fuming mad about the lack of decent options for cadmium as a plating material. A couple made comments in a recent study conducted by the Reed Business Information Research Department for Design News. “We need an environmentally friendly replacement with decent cost and performance,” says an engineer who designs equipment for in house use. ”These days, cadmium is effectively banned for environmental reasons, but none of the possible replacements meet all the performance requirements.” Cadmium has been widely used as a plating material because it offers good corrosion resistance, cathodic protection of steel, galvanic compatibility with aluminum, as well as excellent lubricity. Cadmium can be dyed to many colors and can be used as a final finish or a paint base. Inhalation of cadmium-containing fumes can result in chemical pneumonitis, pulmonary edema, and death. Human exposures to environmental cadmium are primarily the result of the burning of fossil fuels and municipal wastes It’s one of six substances banned by the European Union’s Restriction on Hazardous Substances (RoHS) directive.

A make-your-own Star Wars Sith Lightsaber hilt is heftier and better-looking than most others out there, according to its maker, Sean Charlesworth. You can 3D print it from free source files, and there's even a hardware kit available -- not free -- so you can build one just in time for Halloween.
Some next-generation bio-based materials are superior in performance to their petro-based counterparts, but also face some commercial challenges. This is especially true of certain biopolymers, adhesives, coatings, and advanced materials.
Cars and other vehicles, as well as electronics and medical devices, continue to lead the use cases for the new plastics products we've been seeing, as engineers design products for tougher environments.
LeMond Composites, founded by three-time Tour de France cycling champion Greg LeMond, is the first to license a new carbon fiber production method invented by Oak Ridge National Laboratory (ORNL) that's faster, cheaper, and greener.
This month will mark the launch of the SpeedFoiler, a super-fast, ultra-lightweight foiling catamaran that can fly short distances over water faster than other foiling designs, in part because of its carbon composite materials.
