“My culinary vision stems from a deep concern for the critical challenges facing global food systems today. The urgent need to feed an ever-growing world population under increasingly unstable environmental conditions represents one of humanity’s most pressing issues. Many experts, myself included, firmly believe that future food systems will inevitably have to lean heavily on computational technologies to ensure efficiency, enhance control, optimize processes, minimize food waste, and allow for the precise tailoring of personal diets. The implications for sustainability and personalized nutrition are immense, and digital solutions offer a powerful pathway forward.
Having worked extensively in the field of hybrid craft—which fundamentally involves merging digital and traditional making practices across various domains—I have always found myself profoundly attracted to cooking. I view cooking not just as a necessity, but as a unique and intricate form of craft, rich in tradition, creativity, and sensory experience. Therefore, it was a very natural progression for me to shift my research interest towards the captivating domain of Digital Gastronomy. Within this field, we pose a fundamental question: how can a chef fully leverage and enjoy the immense creative potential that digital technologies can introduce to the established art of traditional cooking? It’s about empowering culinary artists with new expressive capabilities, enabling them to explore textures, shapes, and flavors in ways previously unimaginable, pushing the boundaries of what food can be.”

3DN: What are you able to do with digital fabrication in the kitchen?
“Currently, our research is keenly focused on a very specific and impactful contribution: the development of innovative tools—comprising both sophisticated software and advanced hardware—along with novel recipes that compellingly demonstrate the creative power computers can bring to the act of cooking. Our primary aim is to equip cooks with unprecedented capabilities to control flavor in a discrete, local, and incredibly precise manner. Imagine being able to place specific flavor profiles exactly where you want them, or to create complex flavor gradients within a single bite.
To draw an analogy, think about the revolution that Computer-Generated Imagery (CGI) and advanced image processing introduced to traditional photography. When we transitioned from the analog medium to the digital realm with digital cameras, the concept of pixels, and powerful editing software, photographers gained an unparalleled level of control over every aspect of an image. They could manipulate light, color, and composition with exactitude. Digital Gastronomy seeks to achieve a similar paradigm shift for food. By integrating digital fabrication, we are moving beyond traditional methods that often offer only macroscopic control, towards a future where chefs can sculpt flavor, texture, and nutritional content at a microscopic level, opening up a boundless spectrum of culinary innovation and personalized eating experiences.”
3DN: Can you tell us more about the technology and software you use?
“Our technological journey in the lab has evolved significantly. Initially, we started our experiments with a modified version of a Printrbot 3D printer, which we adapted with a specialized paste extruder. This allowed us to print with various food-grade pastes and explore basic shape creation. However, to achieve greater precision, versatility, and scalability, we have since transitioned to utilizing a state-of-the-art Universal robot-arm. This robotic system works in conjunction with a custom-developed extruder that features a changeable nozzle diameter, providing unparalleled control over deposition and material flow, crucial for intricate food designs.
Beyond 3D printing, our lab employs a suite of other advanced digital fabrication techniques tailored for culinary applications. We actively work with a laser cutting machine, which we harness for precise laser-induced heating. This capability allows us to achieve controlled browning, caramelization, or even localized cooking effects with incredible accuracy, opening up new possibilities for texture and flavor development. We also integrate CNC milling into our processes, primarily for creating highly customized and complex molds. A particularly exciting development is our custom-designed ‘programmable’ mold technology, which allows us to dynamically change the shape of the casting mold. This feature is especially beneficial for crafting innovative and visually stunning desserts, offering chefs the ability to rapidly iterate on design and create bespoke culinary forms.
On the software front, we are actively developing proprietary control software and a specialized Graphical User Interface (GUI). This bespoke software is designed to be intuitive and powerful, enabling chefs to digitally generate and customize the intricate shapes of 3D printed noodles, for instance, or other complex food structures. The goal is to provide a user-friendly interface that translates complex digital design parameters into tangible culinary creations, making advanced fabrication accessible to those without extensive engineering backgrounds.”

3DN: What are the biggest challenges of trying to integrate digital fabrication instruments in cooking?
“Integrating digital fabrication instruments into the kitchen environment presents several significant hurdles that we are actively working to address. Firstly, there is currently an insufficient supply of digital cooking tools that are simultaneously flexible, reliable, and fast enough to meet the dynamic demands of a professional or even a home kitchen. Traditional cooking often involves rapid changes and intuitive adjustments; digital tools need to match this agility while also offering robust and consistent performance.
Secondly, the cost factor is a substantial barrier. Advanced robotic arms, for example, which offer the precision and dexterity required for intricate food manipulation, are currently quite expensive. For widespread adoption, especially in domestic settings, these costs will need to decrease significantly to become economically viable for the average consumer or even many smaller restaurants.
Thirdly, the existing software landscape poses a major challenge. Current CAD (computer-aided design) tools, while powerful for engineering and industrial design, are simply not sufficient or intuitive enough for the unique requirements of culinary design. Food materials have complex properties – they are often viscoelastic, temperature-sensitive, and undergo chemical changes during cooking. An ideal ‘culinary CAD’ software would need to account for these nuances, allowing chefs to design not just shapes, but also textures, flavor profiles, and even nutritional compositions, with an interface tailored to culinary thinking rather than mechanical engineering.
Finally, and perhaps most crucially, there is the challenge related to gastronomy culture itself. Food is deeply rooted in tradition, sensory experience, and human connection. If we fail to develop truly meaningful methods, innovative recipes, and appealing dishes that resonate with both chefs and consumers, this technology, no matter how advanced, will simply not be adopted. The integration must feel natural, enhance the culinary experience, and offer clear, tangible benefits that go beyond mere novelty. It’s not just about what technology can do, but what it can create that people genuinely desire to eat and experience. This cultural aspect is paramount to the success of Digital Gastronomy.”
