3D Printing

Although it's possible to 3D-print metal objects, such items can't always be formed down to the sub-millimeter precision required for certain applications. A new technique, however, allows them to be infinitesimally tweaked after being printed.

Although 3D printers can produce a wide variety of objects, the size of each item is limited by the size of the printer. Scientists have now developed a way of getting around that limitation, using a resin that expands when heated.

3D printing may indeed allow for the creation of intricate objects, but what happens if you want to apply a coating to all of those nooks and crannies? Well, a newly-adapted technology should let you do so easily, with a minimum of waste.

While consumer-grade 3D printers may be adequate for making things like models or curios, they're not always up to the task of creating objects that stand up to real-world use. That could be about to change, though, thanks to a new printing filament.

A type of natural polymer, cellulose has increasingly been finding use as an eco-friendly, biocompatible 3D-printing material. Now, scientists have devised a method of printing complex objects with a higher cellulose content than ever.

Founder of Prusa Research, the world’s largest 3D printing factory located in Prague, Josef Prusa has spoken about how the company is doing everything it can to aid the production of much needed medical supplies during the COVID-19 crisis.

While large 3D-printed objects such as buildings may get a lot of attention, the technology is also used to produce tiny, intricate objects. The latter could soon be whipped up faster and in more detail than ever, thanks to a new printing system.

As is the case with items that are manufactured in more traditional manners, it's certainly possible for 3D-printed products to be counterfeited. A new system could help identify such bogus goods, by printing a unique code right into objects.

The quality of 3D-printed metal parts could soon improve, thanks to new research out of Australia. Scientists there have determined that the application of ultrasound boosts the strength of such items, by modifying their microstructure.

If you wanted to have a replica of Michelangelo's David in your home, you'd need plenty of space to show it off. But the replica 3D-printed by Exaddon and ETH Zurich would fit in any home, though you may need a microscope to see it.

Germany's BigRep has unveiled a design prototype of a sporty little number called Loci made up of 14 3D-printed parts, plus an electric powertrain and self-driving tech. Two more concept variants have also been revealed.

Of all the materials that can be 3D-printed, glass is still one of the most challenging to work with. Scientists at the ETH Zurich research center are working on changing that, though, with a new and reportedly better glass-printing technique.
