Researchers from the University of Birmingham and the University of Huddersfield, UK, have developed a new 3D bioprinting technique that can be used to treat chronic wounds.

Named Suspended Layer Additive Manufacturing (SLAM), the approach enables the printing of a novel biomaterial that accurately simulates the structure of mammalian skin.

In fact, according to the researchers, the biomaterial is the first of its kind to simulate all three of the major layers found in skin – the hypodermis, the dermis, and the epidermis – making it a unique tri-layered skin equivalent. Early experiments suggest that the 3D bioprinted skin can be placed at the site of a wound to induce healing, reducing scar tissue in the process.

The ability to 3D print integrated circuits and other semiconductor devices directly into PCBs allows low-volume fabrication of highly specialized devices.

TALLAHASSEE, Florida — A London patient, Steve Verze, became the first to use a 3D-printed prosthetic eye in November 2021. Its advancements in aesthetics, durability and production process allude to an auspicious future for prosthetics. Yet, developing countries struggle regarding prosthetic accessibility and affordability. Losing a limb or organ in poverty is extremely impactful since access to prosthetic devices or assistance is rare.

A 3D Difference

Steve Verze made history by replacing his acrylic eye with a 3D-printed prosthetic. Since he was 20 years old, he has worn a prosthetic and expressed that he was always self-conscious wearing it. The difference between his previous eye and the 3D counterpart is wider than expected. Traditional prosthetic eyes take six weeks to finish due to hand painting acrylic. The 3D printing prosthetic takes two to three weeks in comparison. Acrylic eyes require an anesthetic for children due to the challenge of molding them to the eye socket. The 3D eye only uses digital scans and “is a true biomimetic and a more realistic prosthetic, with clearer definition and a real depth to the pupil.” The world’s first 3D-printed prosthetic eye shows advancements that expand the possibilities of prosthetics forever.

A new metal 3D printing technology could revolutionize the way large industrial products like planes and cars are made, reducing the cost and carbon footprint of mass manufacturing.

Why it matters: 3D printing — also called additive manufacturing — has been used since the 1980s to make small plastic parts and prototypes. Metal printing is newer, and the challenge has been figuring out how to make things like large car parts faster and cheaper than traditional methods.

Last week saw an announcement that Optimus Ride, an autonomous shuttle company in Boston was purchased in an acqui-hire by Magna, the Ontario based Tier One Automotive company. In an acqui-hire, the company has generally failed, but a buyer pays to pick up the assets and to hire the team, which took time to create. Usually it’s only enough to reward the preferred investors, the team gets options in their new employer.

Optimus Ride built a shuttle on top of the GEM 6-seater electric shuttle platform, adding sensors and their autonomy tools. It evolved out of MIT.

Also announced as shutting its doors was Local Motors, maker of the Olli shuttle. Local Motors began with a focus on 3D printing to make smaller volume vehicles. The started with the Rally Fighter, a vehicle that was crowd designed after contests. Over time, founder Jay Rogers believed that 3D printing could bring a vehicle to production faster and at lower cost than conventional methods than conventional methods, and entered the Shuttle market, partnering with various partners to make them autonomous. Recently, we reported how an Olli shuttle in Whitby, Ontario had a crash resulting in serious injuries. Early reports suggested it was in autonomous mode, but it was later revealed it was being manually driven at the time. That made it mostly a non-story, but the real story of Olli did not go so well, either.

Researchers at University College London (UCL), Universidade de Santiago de Compostela (USC) and biopharma firm FabRx, have managed to convert an everyday smartphone into an on-demand personalized drug 3D printer.

Using the visible light created by a mobile phone screen, the modified M3DIMAKER LUX system has already proven capable of 3D printing blood-thinning tablets in specific shapes, sizes and dosages. Operable via a user-friendly app, it’s hoped that with further R&D, the team’s machine could be deployed in future by those living in isolated areas, under the remote supervision of GPs to ensure patient safety.

“This novel system would help people who need precise dosages that differ from how a medication is typically sold, as well as people whose required dosage may change regularly,” said the study’s lead author Xiaoyan Xu. “The tablet’s shape and size are also customizable, which enables flexibility in the rate at which the medication gets released into the bloodstream.”

3D printed lab meat, and plant based meats will be more widespread in our future. Would you eat stem cell 3D printed lab meat or plant based meat? Why or why not? What are the differences between natural vs unnatural. Growing up in Texas I know most Texans frown on it, as BBQ is a religion. Is 3D printing meat sustainable\.

Whether it comes from a plant or the cells of an animal, it’s becoming increasingly clear that the meat of the future will probably not be coming from the flesh of slaughtered animals. Instead, whether made from plants or cells, it will be formed into ‘meat’ by a 3D printer. In September of 2021, a Japanese team of researchers at the University of Osaka announced that they had 3D printed Wagyu beef. Beef connoisseurs will recognize the name; Wagyu beef is prized (and suitably priced) for its flavor and fat marbling. Legends abound about the cows such beef derives from, how they are allegedly coddled and massaged, fed a special diet that includes beer — but much of those tales are either exaggerated or pure urban legend. As Joe Heitzeberg, the co-founder and CEO of Crowd Cow explains, There are four breeds native to Japan. Of those four breeds, one of the breeds is genetically unique. It has a genetic predisposition to create this crazy marbling of fat on the inside of muscle tissue. No other livestock does that. The researchers at the University of Osaka used two different types of stem cells from Wagyu cows to create cultured meat, growing living animal cells onto some type of matrix where they are then incubated and grown into animal tissue that has never been part of a living animal. There are currently no reports on the taste of the cultured Wagyu beef but we can assume it’s ‘good’ and given a little time, the technology should be able to produce excellent Wagyu cultured meat — at what price, however, is another big question mark. But there’s another simpler solution that could be a better meat replacement than cultured meat, as even meat grown from stem cells still contains cholesterol and some of the negative health concerns associated with animal protein. Plant-based imitation meat is also being created with 3D printers, and the results are surprising even hardcore meat lovers.

Researchers at the Indian Institute of Technology Bhubaneswar, in collaboration with TCS Research and Wageningen University, recently devised a new strategy that could improve coordination among different robots tackling complex missions as a team. This strategy, introduced in a paper pre-published on arXiv, is based on a split-architecture that addresses communication and computations separately, while periodically coordinating the two to achieve optimal results.

The researchers’ paper was recently presented at the IEEE RoboCom 2022 conference, held in conjunction with IEEE CCNC 2022, a top tier conference in the field of networking and distributed computing. At IEEE RoboCom 2022, it received the Best Paper Award.

“Swarm-robotics is on the path to becoming a key tool for human civilization,” Dr. Sudipta Saha, the lead researcher of the team that carried out the study, told TechXplore. “For instance, in medical science, it will be necessary to use numerous nano-bots to boost immune-therapy, targeted and effective drug transfer, etc.; while in the army it will be necessary for exploring unknown terrains that are hard for humans to enter, enabling agile supervision of borders and similar activities. In construction, it can enable technologies such as large-scale 3D printing and in agriculture it can help to monitor crop health and intervene to improve yields.”

In a groundbreaking new study, researchers at the University of Minnesota Twin Cities used a customized printer to fully 3D print a flexible organic light-emitting diode (OLED) display. The discovery could result in low-cost OLED displays in the future that could be widely produced using 3D printers by anyone at home, instead of by technicians in expensive microfabrication facilities.

The research is published in Science Advances.
