3-D+Printing

QR codes are everywhere nowadays, but they don’t have to be. MIT scientists have developed an invisible tagging system called BrightMarker, which embeds fluorescent tags into objects that can be viewed and tracked through an infrared camera.

Scientists have created the world’s smallest wine glass, narrower than a human hair. Made out of actual glass, the model is a test run of a new 3D-printing process that could help make nanoscale glass components for electronic and optical devices.

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.

Sending materials into space is expensive, so the more astronauts can make on-site, the better. Engineers have now demonstrated how crushed Martian rock could be mixed with a titanium alloy to make 3D-printable building materials.

There may soon be new hope for patients born with genetic defects that leave them with misshapen or missing ears. A new human clinical trial will test an implant known as an AuriNovo, which uses a 3D-bioprinted ear grown from the patient’s own cells.

Processing wood from trees isn’t the most efficient way to make furniture or building materials. MIT scientists have made breakthroughs in a process that could one day let us 3D print and grow wood directly in the shape of furniture and other things.

The James Dyson Award is an international competition to encourage students to get creative to solve the world's pressing problems. The national finalists have been announced for 2021, showcasing ideas that help people and the environment.

Eardrum perforations are painful, impair hearing and are tricky to repair. The PhonoGraft, developed at Harvard, is a 3D-printed implant that can patch up damage by encouraging natural cells to regrow, and now it’s ready for commercial production.

A first-of-its-kind 3D-printed concrete bridge has been unveiled in Venice, Italy. The bridge is a demonstration of a new 3D printing method resulting in a structure requiring no mortar or steel reinforcement.

WASP, in collaboration with artist Alison Knowles, has completed the printing stage of the world’s first 3D-printed livable sculpture. “The House of Dust” will be one of 10 temporary sculptures featured at the Museum of Wiesbaden’s tinyBE exhibition.

Heating and cooling systems are some of the biggest energy guzzlers, but passive temperature control could reduce emissions. Phase-change materials show promise for this, and now engineers have developed a new PCM composite that can be 3D printed.

Relativity Space is coming to the 3D-printed rocket party with its freshly unveiled Terran R. Intended for satellite launches and multi-planetary travel, the rocket is fully reusable and can be created from raw materials within 60 days.
