Innovative Breakthrough: MIT's 3D Printer Crafting Bones and Tendons

"Revolutionizing Soft Robotics: MIT's Laser-Guided 3D Printer Crafts Elastic Limbs"

In a groundbreaking leap for 3D printing technology, an international team of researchers from Switzerland and the U.S., in collaboration with MIT, has developed a novel process that extends the capabilities of 3D printers beyond rigid structures. Traditionally, 3D printing has excelled in creating objects from fast-curing plastics, limiting its utility in the realm of soft robotics—robots made of flexible yet robust materials. The challenge lies in the rapid hardening of these plastics, making them less suitable for crafting intricate, elastic components like prosthetic limbs.

The team's breakthrough involves a new 3D printing method that harnesses slow-curing polymers, allowing users to seamlessly integrate both elastic and rigid materials. Published in the journal Nature, their research showcases the creation of a 3D printed hand complete with bones, ligaments, and tendons. What sets this process apart is the integration of a laser sensor array developed by MIT researchers, enabling the printer to visually monitor and adjust its output in real-time.

Thomas Buchner, a robotics researcher at ETH Zurich and lead author of the study, emphasized the advantages of slow-curing polymers, noting their superior elastic properties and faster return to the original state after bending compared to fast-curing plastics. The traditional 3D printing approach relies on UV lamps rapidly curing each layer of fast-curing plastic. However, imperfections require post-cure scraping, risking damage to the final product.

The incorporation of the MIT-developed 3D laser sensor eliminates the need for manual scraping. The sensor scans each layer for irregularities, allowing the printer to make real-time adjustments with pinpoint accuracy during the printing process. This innovative system not only streamlines the production of soft robotics components but also marks a significant stride toward the seamless integration of diverse materials in 3D printing, expanding its applications into previously uncharted territories."
