A company has donated 350 of Smit’s, the biomechanical engineer behind the design, 3D-printed prosthetic hands to war victims in Ukraine.

Delft University of Technology (TU Delft) researchers designed laser-cutting 3D-printed prosthetic hands for Ukranian war victims. Thanks to laser-cutting technology, war victims get their prosthetic limbs more easily. These prosthetic hands are in use in India, and Indian company Vispala donated 350 of Smit’s 3D-printed prosthetic hands to war victims in Ukraine, according to the TU Delft.

3D printers to create rapid on-demand objects have only been around for a short time. It’s a popular technique for making quick mock-ups or temporary solutions, but 3D-printing can also be used for more long-term applications. For example, some museums used it to create tactile models for interactive displays or even to create structural parts to support restoration projects. Either way, these are not temporary whimsical creations, but structures that they would likely still want to be in perfect shape several years down the line.

There are also other reasons to want to preserve 3D-printed materials for more than just a few years, but we haven’t had the technology for long enough to really know what will happen to these objects over time.

To find out, art conservation researchers at the Universidad Complutense de Madrid in Spain subjected two types of 3D printing materials to an artificial accelerated aging process. When plastics age, any damage such as loss of color or chemical changes in the materials are often caused either by UV radiation from exposure to light or by extreme temperature fluctuations. To simulate these extreme environments in a much faster scale than natural aging, the researchers put the 3D printed samples and the original filaments in two different chambers: One exposing the samples to UV light and the other subjecting them to a range of high temperatures.

As Meta faces antitrust scrutiny over its acquisition of VR fitness developers Within, the tech giant is making another acquisition. Meta confirmed to TechCrunch that it is purchasing Luxexcel, a smart eyewear company headquartered in the Netherlands. The terms of the deal, which was first reported in the Belgian paper De Tijd, have not been disclosed.

Founded in 2009, Luxexcel uses 3D printing to make prescription lenses for glasses. More recently, the company has focused its efforts on smart lenses, which can be printed with integrated technology like LCD displays and holographic film.

Researchers in Spain have developed a new porous material capable of regenerating bones and preventing infections at the same time.

The scientists are from the Bioengineering and Biomaterials Laboratory of Universidad Católica de Valencia (UCV).

Tailor-made for each case using 3D printing, the biotech creations contain a bioactive alginate coating. This coating induces bone regeneration and destroys the bacteria that sometimes prevent bone formation from being completed.

Austin, Texas-based 3D printing construction company ICON has gotten some pretty significant projects off the ground in recent years, from a 50-home development in Mexico to a 100-home neighborhood in Texas. This week the company won a NASA contract that will help it get an even bigger project much further off the ground—all the way to the moon, in fact.

The $57.2 million contract is intended to help ICON develop technologies for building infrastructure on the moon, like landing pads, houses, and roads. The goal is for ICON to build these lunar structures using local material—that is, moon houses built out of moon dust and moon rocks.

3D printing machines can build up to 40 percent of homes during the construction process and save money on labor costs, experts say.
