Manufacturing

Engineers have developed a new 3D-printed titanium alloy with a unique microstructure that makes it ultra-strong. Not only is it stronger than other forms of titanium, but it has the highest strength-to-weight ratio of any 3D-printed metal ever made.

Industrial heat consumes a huge proportion of global energy. Rondo Energy says its brick-toasting heat storage device is so cheap and efficient that it makes decarbonization an instant no-brainer across a huge range of industries. Bill Gates agrees.

Although 3D printing technology continues to improve, it's still limited by relatively long print times and low resolution. A new technology could help, by simultaneously utilizing multiple small print nozzles instead of a single big one.

A powerful new adhesive can grip strongly in extreme temperatures, from the deep freeze of liquid nitrogen to the sweltering heat of an oven. Better yet, it can be broken back down into its component parts and reused without losing strength.

Researchers at EPFL have demonstrated a light-based 3D-printing method that's about 30 times faster than conventional additive manufacturing, creating objects in 20 seconds that would normally take more like 10 minutes thanks to photocurable resins.

It’s an unfortunate truth that many important chemical reactions require rare and expensive metals as catalysts. But now, scientists have developed a device that actively tweaks plain old aluminum to make it behave like other metals on the fly.

3D printers may allow small companies to produce prototypes, but the machines aren't really suited to mass production. That's where the Mayku Multiplier is intended to come in – it's billed as being the world's first desktop pressure former.

Although magnesium is known for being lightweight, riveting pieces of it together can be an involved, energy-intensive process. A new technique is claimed to make doing so much simpler, possibly opening up new uses for the metal.

New US President Joe Biden has committed to replace the entire 650,000-strong federal fleet with American-made electric vehicles, kicking off what could be a seismic transformation in the US automotive industry. But will it even be possible?

Researchers at Brown University have developed a new way to make super-hard metals, up to four times harder than usual. The team made nanoparticle “building blocks” that could be fused together under pressure, thanks to a chemical treatment.

Perovskite solar cells are rapidly catching up to silicon in efficiency, but continue to lag behind in production speed. Now Stanford has developed a new method of making perovskite solar cells at up to 40 ft per minute – even faster than silicon.

Engineers at Cornell University have developed a new technique for 3D printing metallic objects – and it involves blasting titanium particles at supersonic speeds. The resulting metals are very porous, making them useful for biomedical implants.
