These 3D-printed QR codes are scannable and edible
A crew from the Singapore College of Know-how and Design has 3D printed a QR code that you could eat. It was completed utilizing a brand new extrusion system design that enables their 3D meals printer to swap simply between filaments. The crew includes 4 members: Cheng Pau Lee, Mervin Jian Yi Ng, Nicole Min Yu Chian, and Michinao Hashimoto.
It is not the primary food-based 3D printer we have seen. We’ve reviewed the Cocoa Press 3D Printer previously and admire its chocolatey contribution to the 3D printing group. This 3D printer, nonetheless, is enticing in that it makes use of a broader number of food-based filaments. As neat as that is, it results in an issue through which so many alternative filament compositions require the nozzle to be swapped between them.
To deal with this difficulty, the crew put collectively a nozzle explicitly designed to modify between filaments when these filaments have differing stress necessities. One other good thing about utilizing one nozzle as an alternative of switching is the seamless transition. It permits for extra exact printing.

To exhibit its means, the crew was capable of print a number of issues out of a number of supplies—one in every of which was a working QR code that may, in fact, be eaten after it is scanned. The crew printed findings from their analysis and growth in a current difficulty of Future Meals. In it, they clarify the nozzle’s design course of and supply photos alongside the way in which.
Dr. Lee elaborated on the attainable use instances for his or her work, explaining that it may very well be a software to assist people meet particular dietary necessities. Alternatively, it may very well be applied for extra enjoyable endeavors just like the edible QR code instance or different interactive designs. The door is open to take some tasty inventive liberties.
