3-D printed chocolate to start reaching consumer market

BLOOMBERG – Hotels, pastry chefs and coffee chains can soon start offering guests customized 3-D printed chocolate thanks to a little-known Swiss chocolatier.

Barry Callebaut, the behind-the-scenes producer of a quarter of the world’s chocolate, is giving gourmet clients access to a method of printing personalized designs en masse, the Zurich-based company said in a statement Friday. The technology will first be available through the company’s Mona Lisa brand, which makes chocolate decorations, sprinkles and figurines.

After experimenting with 3-D printing chocolate for years, Barry Callebaut has figured out a way for the printer to handle the tempering of the chocolate, a process that requires constant movement at specific temperatures and which could take as long as an hour in the past. Now, Barry Callebaut’s printers can print thousands of pieces in a much shorter time.

The move comes as the chocolate industry faces meager growth prospects. Barry Callebaut said last month that the global market stagnated in the three months through November. Lindt & Spruengli has said it plans to close 50 stores in the United States (US).

Business clients can come up with their own designs, shapes and sizes, with the final creations fit for use in desserts, confectionery, hot drinks and pastries.

That reflects the current trend of personalisation, consumers wanting to post pictures on Instagram, as well as demand for premium products, Pablo Perversi, Barry Callebaut’s head of innovation, said in a phone interview.

“The important thing is this is not a one-off type of printing like in the past,” he said. “We can produce at scale.”

The Zurich-based company makes chocolate for clients such as Nestle, Unilever and Hershey, whose names then appear on the labels.
