Singapore University of Technology and Design Develops 3D Food Printing Tech for Edible QR Codes

TapTechNews July 7th news, a research team from the Singapore University of Technology and Design has successfully fabricated scannable and edible QR codes using 3D food printing technology. This technology applies a newly designed extrusion system, enabling the 3D food printer to easily switch between different food materials.

As TapTechNews understands, 3D food printing technology is not new. However, this 3D printer at the Singapore University of Technology and Design is even better because it can use multiple types of edible materials. Although the rich materials bring more possibilities, it also poses a problem. Different materials often require different extrusion pressures, which requires frequent nozzle replacements.

To solve this problem, the research team designed a new type of nozzle that can flexibly switch between materials requiring different extrusion pressures. This single-nozzle design not only simplifies the operation process but also realizes seamless printing, resulting in higher precision.

To demonstrate the power of this technology, the research team printed some items with multiple materials, one of which is the scannable and edible QR code. The relevant research results were published in the recent issue of Future Food Journal, and the paper detailed the design process of the nozzle with attached pictures.

When the research team talked about the future applications of this technology, it said that it can help people personalize food according to specific dietary needs. At the same time, this technology can also be used in more interesting fields, such as making edible QR codes and other interactive food designs, bringing more creative space to the culinary arts.
