We’ve seen 3D printers create cake decorations, personalized vitamins, and even cultured beef. And now, thanks to Print a Drink’s robot, we’ve seen custom designs printed inside a cocktail. You might think such beverage witchcraft would be impossible. I mean, how could a design be suspended and hold its shape in anything other than a jello shot? Turns out it just takes the right drink, the right droplet and the precision of a robotic arm.
Based in Austria, Print a Drink has actually been around for three years. It was started by Benjamin Greimel as a university research project. Since that time, Print a Drink has created two working robots (one in the U.S. and one in Europe) that up until the pandemic would travel to special events and conferences printing out custom designs inside drinks at parties and such.
So how does it work? Print a Drink uses a robotic arm with a custom-made printer head attached to it. The robot uses a glass needle to inject a food-grade, oil-based liquid inside a drink. The drink itself needs to be less than 40 percent alcohol and can’t be a straight shot of something like vodka or whiskey because the injected beads won’t hold and will float to the surface. Greimel explained to me via video chat this week that the combination of liquid density, temperature and robotic movement allow the designs to last for roughly 10 minutes before dissipating.
Coordinating all those puzzle pieces is complicated to say the least. In addition to setting up the robot at an event and operating it, there are specific requirements around drinks that can be used, and designs need to be uploaded into the robot. Plus, there are safety concerns because the robotic arm does move about pretty quickly. Because of all those reasons, Print a Drink’s business has been around renting the robot ($2,500 – $5,000, depending on the event) and not selling them outright. In addition to all of the complications above, staff would need to be trained properly on how to use the machine, and chances are good that the people operating the devices are not roboticists who can troubleshoot.
To make Print a Drink more accessible, Greimel and his partner (the only two people at the company) have developed a smaller, self-contained version of the robot that is roughly the size of a countertop coffee machine. But don’t expect a consumer version for your next backyard soirée. This smaller version is still complicated, and still requires training, so the company is targeting large corporations like Disney or a hotel chain like Hilton where it could be installed and used for special events or promotions. Greimel said the first prototype of this smaller Print a Drink will be available in the next week.
Though more specialized, Print a Drink is part of a bigger automation movement happening with booze right now. In addition to robot-powered bars like Glacierfire popping up, we’re also seeing automated drink dispensing vending machines from Rotender and Celia start to hit the market. It’s not hard to see all of these types of robots working in tandem, however, with a robo-bartender pumping out standard cocktails, while Print a Drink prints up specialty drinks customized for special occasions. We’ll drink to that.
