3-D printing

BBC Click reports on a system developed by CSAIL researchers that creates 3-D motion sculptures based off of 2-D video. The technique, say the researchers, “could help dancers and athletes learn more about how they move.”

In an article for Popular Mechanics, Tiana Cline spotlights SoFi, an autonomous, soft, robotic fish that can swim alongside real fish. “SoFi has the potential to be a new type of tool for ocean exploration and to open up new avenues for uncovering the mysteries of marine life,” Cline notes.

NBC Mach reporter Tom Metcalfe writes that MIT researchers have developed a technique to 3-D print soft objects that change shape in response to magnetic fields. “You can imagine this technology being used in minimally invasive surgeries,” explains Prof. Xuanhe Zhao. “A self-steering catheter inside a blood vessel, for example — now you can use external magnetic fields to accurately steer the catheter.”

MIT’s Self-Assembly Lab collaborated with Swiss designer Christoph Guberan on a collection of 4D-printed “functional inflatable lamps, vases, and vessels,” which are now for sale at a New York gallery. “Rather than setting out to create a preconceived set of products, the resulting works were organically formed as an extension of the research process itself,” writes Aileen Kwun for Fast Company.

Tasker Smith, a technical instructor in the Department of Mechanical Engineering, writes for Make Magazine about his work developing 3-D printed tools to create a custom leather press. “By marrying the versatility of digital design and fabrication with luxurious materials like leather,” writes Smith, “we can supercharge our process and generate customized artifacts worthy of handing down from generation to generation.”

MIT researchers have developed a new technique to 3-D print magnetic robots that could one day be used as biomedical devices, reports Erik Olsen for Quartz. “The engineers have enabled the bots to roll, crawl, jump, and even snap together like a Venus flytrap to grasp a pill and then roll away with it,” explains Olsen.

MIT researchers have created a new fabrication technique to create intricate, 3-D printed magnetic options that react to magnetic fields hitting them at different angles, reports Mark Wilson for Co.Design. In the future the structures, “could be placed in the human body, manipulated via wireless, harmless magnetism, and carry out intricate tasks like on-site drug delivery.”

Prof. Xuanhe Zhao and his colleagues have designed a 3D printer that can create shape-shifting soft materials. The group purposefully created the “materials and the method to be user friendly to enable a wide range of applications,” reports Fiona McMillan for Forbes.

Prof. Xuanhe Zhao speaks with WBUR about how he and his colleagues have developed a new technique to create soft, pliable structures that could carry out medical procedures within the human body. “Since the human body is soft, it's beneficial to develop a device that has a similar rigidity as soft tissues in the human body,” explains Zhao.

In this video, Mashable highlights a new method developed by MIT researchers to 3-D print soft robots that can crawl, fold and carry a pill. The team hopes the structures, which can be controlled with a magnet, could eventually be used as a medical device to take tissue samples or deliver treatments.

Lara Lewington reports for BBC Click on how MIT researchers have developed a technique to create 3-D printed soft structures that can be controlled with a magnet. Lewington explains that the structures could eventually be used in biomedical devices to “take images, extract samples, deliver drugs or even surround a blood vessel to control the pumping of blood.”

Researchers at MIT have created 3D-printed structures that can be controlled by a magnet. The structures included a tube that could squeeze shut, a sheet that could fold, and “a spider-like ‘grabber’ that could crawl, roll, jump, and snap together fast enough to catch a passing ball,” reports Mu Xuequan for Xinhua.

Using magnetic nanoparticles that have been mixed into rubber, Associate Prof. Xuanhe Zhao has created “3D printed shapes that fold, morph, and move in the presence of a magnetic field,” reports Leah Crane for New Scientist. In the future, Zhao believes this work could have medical applications, “like assisting minimally invasive surgeries,” notes Crane.

NBC Mach reporter Tom Metcalfe writes that MIT researchers are developing autonomous boats that could be used to ferry goods and people and could help ease traffic congestion. “We believe that with fleets of very agile autonomous boats we can offload some street traffic onto the waterways,” explains Prof. Daniela Rus.

Co.Design reporter Jesus Diaz writes that MIT researchers have developed a new technique to 3-D print photorealistic representations of objects. Diaz explains that this could have significant potential in education and scientific visualization: “While you can look at a 3D representation of data in virtual or augmented reality, looking at a real physical model is an experience that is hard to beat.”
