Self-repairing shoes may be a reality thanks to 3D-printed rubber

Posted by in categories: 3D printing, robotics/AI

Circa 2019 :3


Shoes will invariably wear out with enough use, but scientists might have found a way to delay the shopping trip for their replacements. A USC team has created a self-healing 3D-printed rubber that could be ideal for footwear, tires and even soft robotics. The effort involves 3D printing the material with photopolymerization (solidifying a resin with light) while introducing an oxidizer at just the right ratio to add self-healing properties without slowing down the solidifying process.

New 3D printer makes multi-material robots

Posted by in categories: 3D printing, robotics/AI

This charming conical flask-carrying robot was created by a 3D printer capable of printing with multiple different materials, at a speed and level of detail that was previously impossible. And in the future it could have some, well, slightly more useful applications…

Oak Ridge National Laboratory is developing a 3D printed nuclear reactor core

Posted by in categories: 3D printing, nuclear energy

Researchers at the US Department of Energy (DOE)’s Oak Ridge National Laboratory (ORNL) are developing a nuclear reactor core using 3D printing.

As part of its Transformational Challenge Reactor (TCR) Demonstration Program, which aims to build an additively manufactured microreactor, ORNL has refined its design of the reactor core, while also scaling up the additive manufacturing process necessary to build it. Additionally, the researchers have established qualification methods to confirm the consistency and reliability of the 3D printed components used in creating the core.

“The nuclear industry is still constrained in thinking about the way we design, build and deploy nuclear energy technology,” comments ORNL Director Thomas Zacharia.

Rubber “exoskeleton” lets liquid metal structures retain their shape

Posted by in categories: 3D printing, cyborgs

This could allow for nanosuit armor :3.


Imagine if there were a metallic device that could be transported all squished down into a compact ball, but that would automatically “bloom” out into its useful form when heated. Well, that may soon be possible, thanks to a newly developed liquid metal lattice.

Led by Asst. Prof. Pu Zhang, a team of scientists at New York’s Bingham University started by 3D printing lattice-type structures out of an existing metal known as Field’s alloy. Named after its inventor, chemist Simon Quellen Field, the alloy consists of a mixture of bismuth, indium and tin. It also melts when heated to just 62 °C (144 °F), but then re-solidifies upon cooling.

Community First! Village 3D-Printed Affordable Homes

Posted by in categories: 3D printing, habitats

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.

Engineers, medical team design 3D-printed ventilator that requires no electricity

Posted by in categories: 3D printing, biotech/medical, cyborgs, military

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.

A new flexible piezoelectric composite for 3D printing

Posted by in categories: 3D printing, energy

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, 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.”

This New Smartphone-Based DNA Test Could Help Track Disease in Real Time

Posted by in categories: 3D printing, biotech/medical, computing, mobile phones

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.
