Scientists around the world are developing revolutionary means by which to 3D print parts of the human body, from skin to internal organs.

In solar cells, the cheap, easy to make materials called perovskites are adept at turning photons into electricity. Now, perovskites are turning the tables, converting electrons into light with an efficiency on par with that of the commercial organic light-emitting diodes (LEDs) found in cellphones and flat screen TVs. And in a glimpse of how they might one day be harnessed, researchers reported last week in Science Advances that they’ve used a 3D printer to pattern perovskites for use in full-color displays.

“It’s a fantastic result, and quite inspirational,” says Richard Friend, a physicist at the University of Cambridge in the United Kingdom whose team created the first perovskite LED in 2014. The result raises hopes that the computer screens and giant displays of the future will consist of these cheap crystalline substances, made from common ingredients. Friend cautions, however, that the new perovskite displays aren’t yet commercially viable.

The materials in current semiconductor LEDs, including the organic versions, require processing at high temperatures in vacuum chambers to ensure the resulting semiconductors are pristine. By contrast, perovskites can be prepared simply by mixing their chemical components in solution at room temperature. Only a brief heat treatment is needed to crystallize them. And even though the perovskite crystals end up with imperfections, these defects typically don’t destroy the materials’ ability to emit light.

Martine Rothblatt wants to end transplant shortages with 3D-printed lungs.

NASA has chosen the winner in its contest to design habitation for humans on Mars. It will be built on the red planet using a 3D printer and concrete made from pulverised Martian rocks.

A team of bioengineers has successfully 3D-printed tissues they believe doctors could one day implant into patients to help heal the knee, ankle, and elbow injuries that have ended the careers of countless athletes.

“I think this will be a powerful tool to help people with common sports injuries,” Rice University researcher Sean Bittner said in a press release — though the impact of the group’s work could extend far beyond the turf or pitch.

Relativity Space is working to 3D print the Terran 1 rocket in 60 days using laser printing and direct energy deposition. They will have a test flight in 2020 and will have commercial flights in 2021.

They use proprietary materials which are custom designed for printing. They are using stronger alloys designed to take advantage of Stargate’s printing physics. They have highly reliable materials for printing rocket structures and are using an in-house metallurgy and material characterization lab.

A new network of 3D-printed gun advocates is growing in America – and this time things are different. Unlike previous attempts to popularise 3D-printed guns, this operation is entirely decentralised. There’s no headquarters, no trademarks, and no real leader. The people behind it reckon that this means they can’t be stopped by governments.

A decentralised network of gun-printing advocates is mobilising online, they’re anonymously sharing blueprints, advice and building a community. There’s no easy way they can be halted.

Regenerative medicine and stem cells are often uttered within the same breath, for good reason.

In animal models, stem cells have reliably reversed brain damage from Parkinson’s disease, repaired severed spinal cords, or restored damaged tissue from diabetes, stroke, blood cancers, heart disease, or aging-related tissue damage. With the discovery of induced pluripotent stem cells (iPSCs), in which skin and other tissue can be reversed into a stem cell-like state, the cells have further been adapted into bio-ink for 3D printing brand new organs.
