Popular Science reporter Mack DeGeurin spotlights Foodres.Ai Printer, an AI-assisted 3D printer developed by MIT researchers that is “capable of converting food scraps into coasters, cups, and other everyday kitchen items.” The researchers hope their invention “can repurpose waste before it reaches trash cans or compost bins, helping to foster ‘hyper-local circular economies.’”
Interesting Engineering reporter Saoirse Kerrigan spotlights a number of MIT research projects from the past decade. MIT has “long been a hub of innovation and ingenuity across multiple industries and disciplines,” writes Kerrigan. “Every year, the school’s best and brightest debut projects that push the boundaries of science and technology. From vehicles and furniture to exciting new breakthroughs in electricity generation, the school’s projects have tackled an impressive variety of subjects.”
Researchers at MIT have created “a resin that turns into two different kinds of solids, depending on the type of light that shines on it,” a development that could “significantly speed up the 3D-printing process,” reports Andrew Corselli for Tech Briefs. Graduate student Nicholas Diaco explains that this new method “allows us in a single 3D print, to create structures that either dissolve or don't dissolve away. That lets us automate the most difficult and most expensive step of 3D printing, which is removing support materials after the printing is done.”
Prof. Carlos Portela and postdoc James Surjadi speaks with TechBriefs reporter Andrew Corselli about their work developing a new metamaterial that is both strong and stretchy. “We have demonstrated the concept with these polymeric materials and, from here, we see a couple of opportunities,” Surjadi explains. “One is extending this to more brittle material systems. The real dream will be to be able to do this with glasses, other ceramics, or even metals — things that normally we don't expect to deform a lot before they break. Brittle materials are the perfect candidates for us to try to make into woven-type architectures.”
Researchers at MIT have developed a new technique to fabricate “a metamaterial that is both stretchy and strong,” reports Alex Knapp for Forbes. The researchers also discovered that their new fabrication technique can be applied to the development of new materials, Knapp explains, adding that: “future research will be directed toward developing stretchy glass, ceramics and textiles.”
Chronicle visits Prof. Skylar Tibbits and the Self-Assembly Lab to see how they are embedding intelligence into the materials around us, including furniture, clothing and buildings. Prof. Caitlin Mueller and graduate student Sandy Curth are digging into eco-friendly construction with programmable mud by “taking a low-cost material and a really fast manufacturing system to make buildings out of very, very low climate impact materials.” Says Tibbits: “MIT is a really wild place, and most people know of it for its technical expertise…But what I am really inspired by is on the creative end, the design spectrum. I think the mix of those two is super special.” He adds: “We can ask the right questions and discover new science, and we can also solve the right problems through engineering.”
MIT researchers have developed a method to grow artificial muscle tissue that twitches and flexes in multiple, coordinated directions, and could be useful for building “biohybrid” robots, reports Andrew Corselli for Tech Briefs. Prof. Ritu Raman explains that her lab is focused on creating “artificial muscle tissues that can be used to understand and treat muscle diseases that impact healthy human mobility,” and making “safe muscle-powered robots that can perform complex tasks in dangerous environments that are not suitable for humans.”
MIT researchers have developed a new method to grow artificial muscles for soft robots that can move in multiple directions, mimicking the iris of an eye, reports Mrigakshi Dixit for Interesting Engineering. The researchers developed a new technique called “stamping” to create “an artificial iris-like structure,” Dixit explains. “For this, they 3D-printed a tiny stamp, patterned with microscopic grooves. This stamp is then pressed into a soft hydrogel to create a blueprint for muscle growth.”
Researchers at MIT have demonstrated “fully 3D-printed semiconductor-free resettable fuses,” reports Jesse Allen for Semiconductor Engineering. “The researchers plan to further develop the technology to print fully functional electronics and aim to fabricate a working magnetic motor using only extrusion 3D printing,” writes Allen.
Researchers at MIT and elsewhere have developed a 3D printing method that allows “precise control over color, shade, texture, all with just a single material,” reports Vanesa Listek for 3Dprint.com. This technique “promises a faster and more sustainable solution than traditional approaches relying on multiple materials and nozzle changes,” explains Listek.
Researchers at MIT and elsewhere have developed “a new method of 3D printing that uses heat-responsive materials to print multi-color and multi-textured objects in one step,” reports Laura Griffiths for TCT Magazine. “The method has so far been tested using three heat-responsive filaments including a foaming polymer with particles that expand as they are heated, and wood and cork fiber-filled filaments,” explains Griffiths.
MIT researchers have developed “a new type of reconfigurable masonry using 3D-printed recycled glass,” reports Srishti Gupta for Interesting Engineering. “The team has developed robust, multilayered glass bricks shaped like figure eights,” explains Gupta. “These bricks are designed to interlock seamlessly, similar to LEGO pieces, making them versatile and easy to assemble.”
Designboom reporter Matthew Burgos spotlights how MIT engineers “3D printed recycled glass and produced robust LEGO-like bricks for buildings and facades.” The researchers found that “in mechanical testing, a single 3D printed recycled glass brick can withstand pressures similar to those of a concrete block,” Burgos explains. “This means that the material can be just as robust as concrete, making it ideal for construction.”
Researchers at MIT have developed “3D-printed glass blocks shaped like a figure eight that snap together like LEGOs,” reports Brian Heater for TechCrunch. “The team points to glass’ optical properties and its ‘infinite recyclability’ as reasons for turning to the material,” writes Heater.
MIT researchers have developed a 3D printer that can use “unrecognizable printing materials in real-time to create more eco-friendly products,” reports Andrew Paul for Popular Science. The engineers “detailed a newly designed mathematical function that allows off-the-shelf 3D-printer’s extruder software to use multiple materials—including bio-based polymers, plant-derived resins, or other recyclables,” explains Paul.
