3D Printing News

A note of caution to our viewers: many of these products are only available for pre-ordering and have yet to be manufactured. Others are only hopes/dreams. Hyperbole is the language of choice, so be careful!

Additionally, be forewarned that some of the materials you intend to work with, as well as particles and fumes from the printer itself, may be toxic.

A team at the Centre for Tramslational Bone, Joint, and Soft Tissue Research at the University of Dresden in Germany has discovered that a new bioink developed for printing human cells can be altered to print 3D plant cells as well. They are excited by the possibilities for structures in space, since green bioprintng can potentially keep alive mammalian cells or even tissues. It is expected that a two-treatment methodology could be developed which would first reduce inflammation and then foster vascular growth.

Scientists at the Lawrence Berkeley National Laboratory in California have discovered a way to make water and oil stick together by adding a third ingredient, like mustard or soap. The resulting compound can alter its shape and hold the new shape for several months. Their method involves adding tiny gold nanoparticles to the water and a ligand to the oil. The two new materials formed a glass-like structure between the two liquids, enabling the water to assume whatever shape the researchers wanted. The new material is self-healing and can now be made into complex shapes like lattices, spirals, and even threads that are tinier than a human hair. They even anticipate all-liquid circuits.

By printing copper, iron, and ceramics all at once, scientists at the TU Chemnitz in Germany have 3D printed every part needed in an electric motor for the first time. Part of the process involved the use of more advanced 3D printed ceramics, adding much higher levels of heat resistance. In addition to withstanding higher temperatures, the new process conducts heat more efficiently. The new 3D printed electric motor is being shown at the Hannover Messe trade fair this April.

A completely 3D printed 1st century roman helmet has won the top prize in the finishing competition at the Additive Manufacturing Users Group annual conference in St. Louis, Missouri. Produced by Custom Prototypes, based in Toronto, the helmet uses 3D printed metal, 3D printed hair and 3D printed clear plastic (for the gems and stones). After printing, the helmet was extensively sanded and polished using manual and electro polishing, plated in nickel and 24 carat gold.

Here's a video that shows you how artificial intelligence produces a 3D model of a human without special photographic equipment. All that is required is a few seconds of video.

Several of you have requested examples of 3D printed jewelry. Here are some pieces from Metallicity in Cary, North Carolina. The two designers behind this company have each been creating jewelry for over 25 years. Now they use CAD software and send their designs to be printed in New York on large-scale 3D printers.

Researchers at USC Viterbi School of Engineering have succeeded in 3D printing acoustic panels that can turn off vibrations and waves. The engineers used metamaterials which can morph according to their surrounds. Usually 3D printed pieces are fixed and cannot be changed once fabricated. With these metamaterials, changes can be effected from an external environment.

Airbus has been collaborating with Materialise to make 3D printed spacer panels to retrofit cabins. Material weight is reduced by 15%, cost is reduced as well, and customization is feasible. The parts are being used on Airbus's A350 XWB, and are painted with flame-retardant materials after being 3D printed.

Take a look at Olli, a 3D printed transportation vehicle for tomorrow's world. Also discussed here are using 3D printing for skateboards, cars, bicycles.

Usually large or complex 3D prints required extensive post-production to produce a finished product.Now a Czech filament manufacturer, Fillamentum, is offering PLA Extrafill with a range of glitter finishes in different pearlescent colors.

Engineers in France have just released photos of their first 3D printed public housing. Built in Western France, the house is constructed on site, including the foundation and flooring, and then a special robot is hired to print the walls. The robot uses a special polymer material for two outside layers which are then combined with a concrete inner layer for insulation. The five-room house has sensors to monitor air quality, temperature, humidity, and acoustics.

Researchers at Lawrence Berkeley National Laboratory have come up with an all-liquid 3D print structure which can lead to a new variety of products. The scientists explain: "We can stretch water into a tube and it remains a tube. Or we can shape water into an ellipsoid and it reamins an ellipsoid."

With the increasing use of graphene, concern has arisen regarding the large amounts of organic solvents used in its production. Researchers at the National University of Singapore (NUS) and Fudan University say that their new process cuts the necessary solvent use in half, making it much much environmentally friendly.

HP has announced that it has designed a zero-gravity printer suitable for use on a space station . The HP ENVY ISS is claimed to be the first new printer model developed for the space station in 18 years. The unusual demands of a printer in space were extensively studied before the new design was approved.

An article in 3D HUBS lays out the properties and uses of the 25 most common CDC machining materials, from choosing what material to use to post production and finishing.

Note: we review hundreds of articles each month, culling the most significant for you. We also welcome suggestions from our viewers for products and processes that we may have missed.
