3D printing could be key to creating authentic-tasting cow's milk, without the cows

3D printing has a whole host of use cases, but one that you might not previously have thought of is the use of additive manufacturing to create cow’s milk — minus the cows.

That’s the mission statement of a startup called Perfect Day Foods, founded by two twenty-something biomedical scientists. The firm has so far raised $4 million from investors. Perfect Day’s plan? To create a lactose-free milk substitute that’s a whole lot closer to the real thing than existing milk substitutes.

“Just before we started this company, my co-founder Perumal Gandhi and I had recently adopted a plant-based diet and were finding it hard to live without some of our favorite foods: namely, ooey, gooey, cheesy pizza,” co-founder and CEO Ryan Pandya told Digital Trends.

He continued that the pair knew of people who were using food technology to create meat without animals, and wondered why nobody was doing the same for milk.

“Our goal isn’t to be an alternative, it’s to be delicious,” he continued. “So whether it’s a Perfect Day yogurt, cheese, butter, or ice cream, it will taste as good as the real thing and be better for you. We want to empower people to enjoy the foods they love, while making the world a greener, kinder place. We don’t think you should have to sacrifice one of the other.”

As Pandya explained, Perfect Day uses yeast fermentation to make its milk, utilizing 3D-printed cow’s DNA as part of the process.

“It’s a process akin to craft brewing and … allows us to create real milk proteins that are identical to the ones found in cow’s milk, without a single cow,” he said. “First, we start with a yeast that’s safe and well understood, which we sourced from the USDA. We give this standard yeast a ‘blueprint’ from 3-D printed cow DNA that allows it to ferment sugar and create real milk proteins. We then carefully separate these milk proteins and combine them with plant-based sugar, plant-based fats, and nutrients to produce a product that has the identical taste and texture of cow’s milk, but packs in more nutrition with no food safety or contamination concerns.”

The cream on this already impressive high-tech milkshake? It boasts a significantly longer shelf life than regular cow’s milk.

As to when customers will be able to get their hands on Perfect Day’s vegan, lactose-free, more sustainable milk substitute, Pandya told Digital Trends it won’t be too long. “We’re focused on product formulation and commercialization as we look to bring our products to market by the end of next year,” he said.

Bioprinting research from the lab of Rice University bioengineer Jordan Miller featured a visually stunning proof-of-principle -- a scale-model of a lung-mimicking air sac with airways and blood vessels that never touch yet still provide oxygen to red blood cells. Jordan Miller/Rice University

Scientists have taken a major step towards the 3D-printing of replacement organs. A new technique for bioprinting tissues allows scientists to create vascular networks like those used in the body to transport blood, air, and other fluids.

Digital Trends’ Top Tech of CES 2023 Awards
Best of CES 2023 Awards Our Top Tech from the Show Feature

Let there be no doubt: CES isn’t just alive in 2023; it’s thriving. Take one glance at the taxi gridlock outside the Las Vegas Convention Center and it’s evident that two quiet COVID years didn’t kill the world’s desire for an overcrowded in-person tech extravaganza -- they just built up a ravenous demand.

From VR to AI, eVTOLs and QD-OLED, the acronyms were flying and fresh technologies populated every corner of the show floor, and even the parking lot. So naturally, we poked, prodded, and tried on everything we could. They weren’t all revolutionary. But they didn’t have to be. We’ve watched enough waves of “game-changing” technologies that never quite arrive to know that sometimes it’s the little tweaks that really count.

CES is more than just a neon-drenched show-and-tell session for the world’s biggest tech manufacturers. More and more, it’s also a place where companies showcase innovations that could truly make the world a better place — and at CES 2023, this type of tech was on full display. We saw everything from accessibility-minded PS5 controllers to pedal-powered smart desks. But of all the amazing innovations on display this year, these three impressed us the most:

Samsung's Relumino Mode
Across the globe, roughly 300 million people suffer from moderate to severe vision loss, and generally speaking, most TVs don’t take that into account. So in an effort to make television more accessible and enjoyable for those millions of people suffering from impaired vision, Samsung is adding a new picture mode to many of its new TVs.
[CES 2023] Relumino Mode: Innovation for every need | Samsung
Relumino Mode, as it’s called, works by adding a bunch of different visual filters to the picture simultaneously. Outlines of people and objects on screen are highlighted, the contrast and brightness of the overall picture are cranked up, and extra sharpness is applied to everything. The resulting video would likely look strange to people with normal vision, but for folks with low vision, it should look clearer and closer to "normal" than it otherwise would.
Excitingly, since Relumino Mode is ultimately just a clever software trick, this technology could theoretically be pushed out via a software update and installed on millions of existing Samsung TVs -- not just new and recently purchased ones.
