The machine, which allows chocolate lovers to print their own tailor-made sweets, will be sold by Choc Edge, a company founded by Dr Liang Hao from the University of Exeter.
3D printing is a modelling technology where a 3D object is created by building up successive layers of material.
The process is already used to produce a wide variety of products but this is the first time it has been developed to print chocolate.
While the cost of the printer is unlikely to persuade even the most ardent chocolate fan to part with their hard-earned cash, a number of retailers, including chocolatier Thornton's, have expressed interest in the machine.
The printer, which is available for pre-order on eBay, is expected to sell between 500 and 1,000 machines over the next three years.
Dr Hao said: "The initial worldwide interest in creative and bespoke 3D chocolate products was enormous, so we hope the demand for the printers will also be high.
"By next Easter, consumers will be able to order their own, personalised Easter eggs along with many other chocolate gifts."
