Barry Callebaut, the world’s largest maker of chocolate and cocoa products, is using 3D printing technology to unveil a new service on Wednesday which creates bespoke chocolate bars.

The Zurich-based company said it would work with leading chocolate manufacturers, including leading producer La Maison du Chocolat, to offer what it termed the “ultimate service” for that sector.

For a 2,500 Swiss franc ($2,602) fee, Blythe Masters, the French founder of La Maison du Chocolat, which claims to have invented the elegant humanised chocolate, will test-and-produce a variety of chocolate bars produced using a 3D chocolate printer, which melts individual layers of chocolate blocks.

The chocolate, which is approved by the chocolate manufacturer, is then sent to a warehouse where it is packaged and shipped to consumers around the world.

John Di Bartolomeo, group chief executive at Barry Callebaut, said: “This bespoke chocolate service offers our customers the most innovative and unique chocolate alternative.”

The latest service comes on the heels of a recent announcement from Nestlé, the world’s largest food group, that it would invest $10m in creating a 3D chocolate printer in Germany.

French chocolate company Breyers, which also produces a 3D chocolate printer, is expanding its services to also create custom made custom chocolate cakes, confections and treats.

“The launch of this service is timely as more and more chocolate products are seeking to be replicated in different shapes and sizes by consumers worldwide. This allows consumers to create their own customised chocolate bars or cakes or treats,” said Laura Espinosa, global chief executive of Breyers.

3D printing is becoming more cost-effective and has been hailed as a revolution in the chocolate industry. It allows for the manufacturing of thinner, stronger and flexible shapes, often increasing the amount of chocolate that can be used in the same number of bars and solves the problem of difficult-to-fill cracks.

However, concerns have been raised that 3D printers could pose a health hazard. Some experts have said that the 3D printing of corpses could accelerate the spread of the Ebola virus, since it would have to be modified from a medical error.
