A research team at the Hong Kong University of Science and Technology (HKUST) has unveiled an innovative 3D food printing system that combines the printing process with simultaneous infrared heating. The goal of the development is to overcome common challenges in conventional food printing, such as uneven shaping, microbial risks, and time-consuming post-processing. At the heart of the solution lies a combination of extrusion-based printing, precisely controlled thermal treatment using graphene heating elements, and AI-assisted design software.
The researchers from the Department of Integrative Systems and Design (ISD) utilized generative algorithms to automatically create complex food structures. Python-based scripting processes make it possible for even non-expert users to design personalized meals. The direct thermal treatment during printing stabilizes the structure of starch-based foods and ensures uniform cooking, eliminating the need for external heating steps.
This approach is especially relevant for personalized nutrition, such as in geriatric care or for patients with dysphagia. It also opens up possibilities for controlled nutrient delivery, adherence to specific diets, and creative culinary applications in gastronomy.
“With its potential to streamline food production processes, improve food quality, and cater to individual preferences, this innovation can transform how food is prepared and served in diverse settings, paving the way for a future where personalized and visually appealing food creations are more accessible than ever before,” said Prof. Mitch LI Guijun, Assistant Professor of ISD, who led the research team.
“We’re excited about the potential of this technology to deliver customized, safe, and delicious food with a process that is both efficient and accessible. It represents a significant step forward in how we think about food creation,” Prof. Li added.
Connie LEE Kong-Wai, the paper’s first author and a PhD student at HKUST, said: “We’ve reimagined what 3D food printing can achieve by merging technology and culinary creativity. Our cutting-edge integrative 3D food printing technology can potentially revolutionize personalized food creation.”
During the product’s rollout, restor3d will collaborate closely with select orthopedic centers to gather clinical feedback and further refine the system. The company’s approach centers on the combination of additive manufacturing, digital planning, and personalized surgical solutions.
