BMW is building high-tech footwear for the German bobsleigh team

There’s only a few seconds of running in a bobsleigh heat, but one slip can skittle the whole team. Seeing the need for high-performance ice sport footwear, BMW has jumped in to build custom, 3D-printed traction aids for the 2025 Winter Olympics.Contin… Continue reading BMW is building high-tech footwear for the German bobsleigh team

Red blood cell sports world’s smallest moustache

An electron microscope image of the world's smallest moustache, modeled by a red blood cell

Australian scientists have created the world’s smallest moustache, tiny enough to be modeled by a single red blood cell. Measuring just 5 microns wide, the micro-mo was designed to raise awareness for men’s health.

Invisible QR codes embed object data into infrared tags

Barcodes and QR codes feel like they’re everywhere nowadays, but they don’t have to be. Scientists at MIT have developed an invisible tagging system called BrightMarker, which embeds fluorescent tags into objects that can be viewed and tracked through … Continue reading Invisible QR codes embed object data into infrared tags

World’s smallest wine glass toasts to nanoscale silica 3D printing

Left: The tiny, 3D-printed wine glass. Right: An optical resonator, an example of a fiber optics component that can be 3D printed through the new technique

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 an advanced new 3D-printing process that could help make nanoscale glass components for electronic and optical devices.

New titanium alloy has highest specific strength of any 3D-printed metal

Engineers at Monash University have developed a new 3D-printable titanium alloy with a unique microstructure that makes it ultra-strong. Not only is it stronger than most other forms of titanium, but it has the highest strength-to-weight ratio of any 3… Continue reading New titanium alloy has highest specific strength of any 3D-printed metal

Astronauts could 3D print tools and parts from titanium and Mars dust

Sending materials into space is expensive, so the more astronauts can make on-site, the better. Engineers at Washington State University (WSU) have now demonstrated how crushed Martian rock could be mixed with a titanium alloy to make 3D-printable buil… Continue reading Astronauts could 3D print tools and parts from titanium and Mars dust

3D-printed ear implants grown from patient cells head to clinical trials

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 AuriNovo, which uses a 3D-bioprinted ear grown from the patient’s own cells.Conti… Continue reading 3D-printed ear implants grown from patient cells head to clinical trials

Lab-grown plant matter marks a step towards 3D-printable wood

Chopping down trees and processing the wood isn’t the most efficient or environmentally friendly way to make furniture or building materials. Scientists at MIT have now made breakthroughs in a process that could one day let us 3D print and grow wood di… Continue reading Lab-grown plant matter marks a step towards 3D-printable wood
