3DN: How did the idea of creating Open Meals come about, and what is its relation with 3D printing?

The very first inspiration that ultimately blossomed into the Open Meals project stemmed from a surprisingly analogous concept: the CMYK printing model. Our founder, a visionary art director with a profound appreciation for innovative design and its practical applications, entertained a truly audacious idea. He posed a compelling question: “If the entire spectrum of observable colors can be meticulously decomposed into just four fundamental elements – Cyan, Magenta, Yellow, and Key (black) – why couldn’t an equivalent principle be applied to the vast and complex world of food?” This bold and imaginative analogy became the foundational cornerstone upon which our entire project was built. We meticulously translated this CMYK paradigm into the culinary domain, coining the evocative term SSSB, an acronym that elegantly encapsulates the four fundamental taste profiles that form the bedrock of human flavor perception: Salty, Sour, Sweet, and Bitter. Our initial forays into this concept involved rudimentary experiments utilizing a standard 2D printer, where we explored the feasibility of printing on edible paper with edible inks to create distinct flavor layers. The promising, albeit limited, results garnered from these preliminary tests provided compelling evidence that we were indeed on the cusp of a truly revolutionary discovery. It was at this pivotal juncture, witnessing the latent potential of digital deposition methods for food, that we decisively recognized the inherent limitations of 2D printing for achieving our ultimate vision. Consequently, we made the strategic pivot towards embracing the immense capabilities and transformative power of 3D printing. Additive manufacturing offered the unparalleled precision, intricate structural complexity, and advanced multi-material handling required to bring our vision of deconstructed and precisely reconstructed food elements to vivid life in three dimensions, truly unlocking the full potential of the SSSB model and enabling us to build food, layer by intricate layer, with unprecedented control and artistic freedom.

3DN: Could you explain what technique you are using to 3D print sushi?

The intricate process of 3D printing food, particularly something as nuanced, delicate, and structurally complex as sushi, is fundamentally far from a generic, one-size-fits-all manufacturing solution. At Open Meals, we have committed substantial resources and expertise to the extensive study, rigorous research, and continuous development of a diverse array of specialized methods precisely tailored for the additive manufacturing of various food items. It is critically important to understand that no single, universal 3D printing method can effectively or efficiently handle the vast and inherent diversity of food materials; each ingredient possesses profoundly unique rheological properties, distinctive textural characteristics, and specific behaviors under varying conditions of temperature, pressure, and moisture. Consequently, our approach is inherently bespoke, involving a dynamic process where we adapt, modify, and synergistically combine different 3D printing techniques to meet the specific demands of each culinary creation.

For instance, one of our foundational prototypes, which served as a crucial stepping stone and laid much of the groundwork for our current innovations, was conceptually derived from the well-established FDM (Fused Deposition Modeling) procedures. However, it is essential to clarify that the core FDM technology was not simply adopted wholesale; instead, it underwent profound modifications and extensive re-engineering to precisely accommodate the specific and often challenging requirements of food-grade materials. This involved significant and intricate changes to the extrusion system, the development of sophisticated temperature control mechanisms, innovative nozzle designs optimized for various food consistencies, and even advanced deposition strategies to ensure that ingredients – whether they are viscous pastes, elastic gels, or finely ground powders – could be accurately, consistently, and hygienically deposited layer by meticulous layer without compromising their intrinsic integrity, desired edibility, or sensory appeal. Our ongoing research and development endeavors are fundamentally and continuously driven by the precise characteristics of the specific food materials we aim to 3D print. This material-centric R&D paradigm empowers us to innovate targeted solutions for complex challenges such as maintaining optimal texture, guaranteeing stringent food safety standards, and achieving meticulously desired flavor profiles in the final printed product.

While we are currently diligently working to patent several of our proprietary 3D printing systems and highly specialized techniques – a critical and necessary step to safeguard our innovations and sustain our competitive leadership in this emerging field – we are, at this stage, constrained from divulging the intricate technical details of these cutting-edge processes. What we can share, however, is that our overarching methodology frequently draws conceptual parallels with the engineering principle of “reverse engineering.” In the context of food, this translates into taking existing culinary forms and meticulously deconstructing them down to their elemental and often microscopic components. We then thoroughly analyze and comprehend their molecular structures and physicochemical properties, and subsequently employ additive manufacturing to precisely reconstruct these elements in entirely novel and often complex ways. This allows us to exert unparalleled control not just over the external shape and macroscopic form, but also over the internal structure, the micro-texture, and the precise distribution of flavor compounds within the final product. This level of precision enables us to create truly unique, consistent, and reproducible dining experiences that traditional, manual culinary methods simply cannot replicate, opening up a new frontier for culinary science and artistry.

3DN: How important do you think is the relation between design and food?

This question is not merely important; it is absolutely critical and lies at the very core of Open Meals’ philosophy and operational ethos, particularly given our unwavering and meticulous focus on the intricate textures and holistic sensory experiences of food throughout all our experiments. For us, food transcends its fundamental role as mere sustenance; it is profoundly viewed as an exquisite art form, a versatile medium for boundless creative expression, and an expansive canvas for relentless innovation. Our overarching goal extends far beyond simply replicating existing, conventional dishes; instead, we aspire to create entirely novel forms of food, pioneering new sensations and delivering unprecedented culinary experiences that deeply engage and captivate all the human senses – sight, smell, taste, touch, and even sound.

This is precisely where 3D printing emerges as an utterly indispensable and transformative tool. Additive manufacturing uniquely empowers us to not only conceive but also to precisely actualize designs and intricate internal structures for food that are simply impossible to achieve through even the most skilled traditional human handcraft. The unparalleled precision and geometric freedom afforded by 3D printing technology allow us to manipulate food at an intricate micro-architectural level, crafting sophisticated patterns, multi-layered textures, and bespoke forms. These capabilities can dramatically alter the mouthfeel, precisely control the release of flavors, and profoundly enhance the overall dining experience. This technological prowess opens up an entirely new frontier in gastronomy, enabling us to move decisively beyond the inherent limitations of conventional cooking techniques and manual dexterity, ushering in an era of engineered culinary delight.

To vividly illustrate this transformative potential, we are actively engaged in the ambitious planning of integrating advanced architectural principles directly into our sushi dishes. A prime and compelling example of this is the meticulous incorporation of a specialized structure known as the “negative stiffness honeycomb.” This remarkable design, frequently encountered in cutting-edge engineering and advanced material science, possesses uniquely counter-intuitive mechanical properties that allow it to compress and expand in highly unconventional ways, thereby creating a distinct and often surprising “spring-back” or resilient effect. By embedding such an ingenious structure within one of our sushi creations, we can introduce an entirely unexpected and utterly delightful textural element – perhaps a delicate, initial crunch that transitions into a soft, yielding interior, or a burst of concentrated flavor precisely released by its unique deformation characteristics upon mastication. This endeavor is not merely about achieving visual aesthetics; it is fundamentally about meticulously engineering the entire sensory journey, thereby providing a truly unique and profoundly memorable interaction with the food. The synergistic interplay between cutting-edge design principles and advanced culinary science, meticulously facilitated by 3D printing, enables us to craft sushi that is not only visually stunning and artistically compelling but also offers an unparalleled textural adventure, elevating the dining experience to an entirely new, multi-dimensional plane.
