3D Printing

If an object that's composed of two types of material is going to fail, the break will usually occur at the interface where the two meet. A new type of light-activated 3D printing resin addresses that problem, by gradually morphing from hard to soft states within a single object.

Ordinarily, the 3D printing of multi-colored objects is a relatively complex and inefficient process. That could soon change, however, thanks to a clever new technique in which a temperature-sensitive print media gets "ironed" after being extruded.

A recently developed system could revolutionize the world of 3D printing, by streamlining the adoption of new print media. Such materials could include ones made from all-renewable ingredients, or that are more recyclable than current options.

Scientists have developed a new "ink" that allows objects to be 3D-printed out of wood. The material could reduce the amount of wood that gets wasted in the manufacturing of various products, plus it could utilize existing wood waste.

Scientists have created a 3D-printing media that can take on different colors in different parts of a single print job. The secret lies in utilizing ultraviolet light to selectively alter the surface structure of the material as it's being dispensed.

Researchers have come up with a 3D printing method using liquid metal that's claimed to produce structures at least 10 times faster than existing metal additive manufacturing processes, though it does so at the expense of fine detail.

In order to keep surgeries minimally invasive, it would be great if implants could be injected into the body in liquid form, then solidified once in place. Well, a new ultrasound-based 3D printing process may one day make that very thing possible.

3D printing single objects out of different materials can be difficult, if those materials cure at different rates. The new Inkbit system addresses that problem, and has been used to print a complex functional robotic hand… in just one print job.

If you can 3D-scan it, you can 3D-print it – and Matter and Form has announced a super-versatile new way to do so. The Three system creates photorealistic, high-detail, full-color 3D scans of objects from coins to cars, and potentially beyond.

Although an increasing number of devices are being developed for use on or in our bodies, such devices tend not to be very … "body-like." A new 3D printing resin could change that, by allowing for variable stiffness throughout single objects.

Last year, Anker breezed into the desktop 3D printing space with the AnkerMake M5, launching on Kickstarter to test the market and fund production. Now the company has announced a more affordable follow up called the M5C.

Although there are several methods of 3D-printing metal objects, all of them involve heat – which isn't conducive to producing heat-sensitive electronics, among other things. A new gel, however, can be used to print such items at room temperature.

Different types of metal have different qualities, so combining them can result in items that outperform those made of any one metal. A new technique now allows such mixing to be performed by 3D printers, faster and easier than ever before.

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.

3D concrete printing (3DCP) technology is already known to offer a more efficient approach to constructing buildings. A new type of 3DCP is said to be better, resulting in walls that are a claimed 72% lighter than their conventional counterparts.
