3D Printing

One method of 3D printing involves selectively exposing liquid resin to ultraviolet (UV) light, causing that resin to harden into a solid. Now, scientists have developed a new resin that works with safer, more energy-efficient visible light.

While 3D printing technology does allow for the quicker and cheaper construction of buildings, such structures are typically made of concrete, which isn't very eco-friendly. Soon, though, it may be possible to print buildings out of local soil.

When it comes to the 3D printing of metal, a process known as selective laser sintering (SLS) is most commonly used. An upside-down variation on the technique has now been developed, for printing single objects out of different materials.

3Doodler has launched a 3D printing pen specifically designed for pre-schoolers and above. The 3D Build & Play package comes with a low-heat drawing device, character and accessory molds and colorful backdrops to encourage learning through play.

Although we're hearing more about 3D-printed replacement body parts, those parts need to be implanted via large incisions. That may not always be the case, however, thanks to a new "bio-ink" that could allow parts to be printed within the body.

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.
