Top 5 fields that 3D printing is driving forward

Food

Let’s explore the intriguing world of 3D-printed food. Known initially for printed pizzas and sweets, this technology now extends to meat substitutes and lab-grown meat. It holds the potential to alleviate environmental strains from animal farming and cater to unique nutritional needs.

As stated in the 3D Printing Trend Report 2023, these printers transform digital designs from computer-aided design (CAD) software into edible realities. Unlike traditional printers, they use a variety of soft or paste-like foodstuffs, ranging from pasta and cheese to cookie dough and lab-grown meat.

The printing process is akin to a pastry chef icing a cake intricately. The printer’s arm moves along a predetermined path, shaping the foodstuff into the intended design. As the operator uploads the design, the food, often converted into a paste, is heated inside the machine—not for cooking, but to enhance its malleability for printing.

But, how does it taste? Interestingly, the flavor of a 3D-printed item corresponds to the ingredient loaded into the printer. The printing process, including any heat exposure, doesn’t significantly alter taste.

However, a printer can influence a product’s sensory attributes by applying specific textural patterns called ‘infill.’ Yet, despite these textural variations, the flavor profile remains consistent.
