MIT’s Vision-Controlled Jetting Unleashes Material Innovation


In a groundbreaking leap for 3D printing technology, a collaborative effort between MIT, Inkbit, and ETH Zurich has given birth to a cutting-edge 3D inkjet printing system. Unlike its traditional counterparts, this innovative system not only widens the scope of printable materials but also boasts an impressive speed advantage. Let’s delve into the details of this game-changing technology that has the potential to reshape the future of 3D printing.

MIT Leading a Visionary Leap in 3D Printing Precision

Traditionally, 3D printing relied on nozzles depositing resin, followed by mechanical smoothing to achieve the desired results. However, this method limited the range of materials due to the constraints of slow-curing resins. The new technology eliminates the need for mechanical smoothing by incorporating a visionary approach that utilizes computer vision, turning it into a contactless system.

Vision-Controlled Jetting Technique Unveiled

Building upon the success of the MultiFab 3D printer, the researchers introduced the “vision-controlled jetting” technique. This method employs four high-frame-rate cameras and two lasers to continuously scan the print surface. The computer vision system then analyzes the data in real time, creating a high-resolution depth map that guides the 16,000 nozzles dynamically.

 Precision Printing with Eyes and Brains

Wojciech Matusik, a professor of electrical engineering and computer science at MIT, explains the breakthrough: “This is almost like endowing a printer with a set of eyes and a brain, where the eyes observe what is being printed, and then the brain of the machine directs it as to what should be printed next.” The active feedback loop enables unparalleled precision in the printing process.

The absence of mechanical smoothing components opens the door to the use of slow-curing materials, such as thiol-based materials, offering greater elasticity and durability. The system’s remarkable control allows for the precise printing of intricate structures, demonstrated by the creation of complex robotic devices. Professor Matusik highlights the limitless possibilities, from custom medical devices to semiconductor polishing pads and even more intricate robots.


In the realm of 3D printing, the vision-controlled jetting breakthrough marks just the beginning. As the researchers look to explore materials like silicon, epoxies, and durable polymers, the potential applications span from tissue engineering with hydrogels to the creation of highly intricate robots. The future of 3D printing seems poised for a revolutionary transformation, with this technology paving the way for new material families and unprecedented possibilities.
