Straight from the year 2029.

At 500 square feet, ICON’s stylish new structure was 3D-printed over the course of several days—but it only took 27 hours of labor to construct. The building will serve as a welcome center at Austin’s new Community First! Village—a 51-acre development that will provide affordable housing to men and women coming out of chronic homelessness. Six new 3D-printed homes will be added to the village by the end of this year—and ICON says that they can be built at significantly less cost than conventional homes.

A year ago, ICON proved it could 3D print a home you’d actually want to live in. Now, it’s building a cluster of 3D-printed homes for the homeless.

A research collaboration and ensuing friendship between a trauma surgeon in Oregon and a handful of engineers in Florida has resulted in a new ventilator design that requires no electricity and could be a game-changer during the COVID-19 pandemic.

Albert Chi, who specializes in critical care and prosthetics, was keeping a close eye on COVID-19 during the early days. He immediately began working with his team at Oregon Health and Science University to develop a new, easy way to replicate ventilators that could be deployed anywhere. Specializing in trauma, Chi as a retired commander of the U.S. Navy Reserve and well versed in extreme conditions.

When Chi had a design, he called his friend and clinical-trial collaborator Albert Manero CEO and co-founder of Limbitless Solutions in Orlando, Florida.

Researchers at Peking University, Southern University of Science and Technology and the University of Jinan in China have recently designed a ceramic-polymer composite that can be used to print complex 3D grid architectures. This composite, first presented in a paper published in Nano Energy, was found to exhibit a number of desirable properties, including high flexibility and a high electromechanical energy conversion rate.

Piezoelectric ceramic materials, such as Pb(Zr, Ti)O₃ (PZT) typically have remarkable electromechanical energy conversion capabilities. However, most of these materials are inherently rigid, which makes them far from ideal for the fabrication of flexible electronics.

“Normally, piezoelectric ceramics are brittle, therefore, they are not suitable for integration into flexible electronics directly,” Shuxiang Dong, one of the researchers who carried out the study, told TechXplore. “We wanted to develop a 3D-printed, soft piezoelectric ceramic composite material that is a heat-curable polymer exhibiting mechanical flexibility and a large electromechanical voltage in response to environmental mechanical vibrations or force stimuli. Luckily, we made it, and our composite has great potential to be used for future soft sensors.”

By more accurately printing complex geometric patterns, this new 3D printing method makes construction projects more efficient with less waste and faster time to market.

A new 3D printing method could revolutionize the way additive manufacturing is used to print materials on construction sites.

Scientists typically use a method known as polymerase chain reaction (PCR), but it requires bulky and expensive equipment and considerable expertise to perform correctly. That means DNA samples collected in the field normally have to be sent to dedicated laboratories for testing, which makes it hard to detect diseases or harmful pathogens quickly.

A new testing system developed by researchers at the Army Medical University in China may help to fill that gap by allowing on-the-spot DNA tests in as quick as 80 minutes. According to the researchers, their test achieves 97 percent accuracy using simple 3D printed parts that attach to a standard smartphone and weigh less than 100 g rams (0.22 pounds).

At the heart of the system is an “i-chip” just four centimeters long that includes integrated sample preparation, DNA amplification, and signal detection modules. The various reagents required to carry out the test can be pre-loaded in the device, and the researchers showed that these could be kept for up to ten weeks at room temperature without loss of performance.

It is now possible to use a cheap, lightweight and smartphone-powered DNA detector to identify DNA in blood, urine and other samples, on the spot.

At the moment, testing to identify DNA is usually done in laboratories using expensive, specialised equipment. To make this process faster and cheaper, Ming Chen at the Army Medical University in China and his colleagues developed a portable DNA detector made of 3D-printed parts that attach to a standard smartphone.

An interesting cautionary note on the well-intentioned effort to supply personal protective equipment (PPE), such as masks, via 3D printing. I’ll confess that I have not thought through all the implications.

“One of the hospitals calls it ‘the garage PPE,’” said Sarah Boisvert, founder of 3D-printing school Fab Lab Hub, who works with hospitals to 3D-print materials. “This is a far more complicated problem than just making Christmas ornaments for your family.”

Lovett readily admits that he is not an expert. But he and others who want to help are stymied in part by a lack of clear government regulation around simple designs.
