ZURICH (Reuters) - Barry Callebaut’s chocolate lab has added 3D printing to its e-commerce services, giving visitors to fairs and trade shows a chance to create personalized samples of its products.

In a first step, it gave a 3D-printed chocolate bar to a group of employees who toured a presentation center at its Ettjes cocoa bean factory near Bern.

The Swiss maker of chocolate, chocolate bars and industrial chocolate powder also plans to open an online store where customers can customize chocolate bars for gift giving or bar-mixing with 3D printers.

As part of the Ettjes tour, clients of the new service can choose 1,000 samples from 12 different products, including a stick of “contrast” chocolate and a chocolate bar with an unusual taste: habanero pepper.

The product, which was created using a 3D printer, will be available for a subscription of $249 per month.

Rene Rudiger, the company’s senior managing director for cocoa Americas, said: “We could see that people might like to have a ‘have-one-have-themselves’ option.”

The company will hold a meeting with the Swiss Federal Department of Agriculture and Food in the coming months to confirm commercial arrangements with the government to encourage farmers to increase the production of cocoa beans, he said.
