Brief Introduction: This paper describes a practical and simple approach to designing personalized chocolate products using engineering software for 3D design and rapid prototyping techniques. Advanced technologies reduce production time, costs and even allow production of custom made products on demand. The feasibility of this approach was verified with development of a new personalized product, a box of chocolates that resembles the university crest.

Diagram of design and production

Materials and methods: Advanced engineering software for 3D design has been used to design and model a university crest. The model was manufactured on a rapid prototyping machine, i.e. ZCorp 450 3D printer. After cleaning and fixing with Z - Bond adhesive physical model was ready for mold manufacturing.

Z-Print 450 3D Printer DMU 50 – ECO CNC Mill

3D printed model of university crest

RTV silicone was used to form the mold by casting around the 3D printed model. After silicone curing the mold was ready for chocolate production.

Casted mold from 3D printed model

Foil holders for finished chocolates are formed with the steel tool manufactured on the DMG50eco CNC machine. The tool was designed in 3D design software CatiaV5 by making a “negative” from the university crest model mentioned earlier. The sheets of foil are cut in the right dimensions, overlayed over the tool and then formed with the heat gun to get the imprint (shape) for holding chocolates. Also the packaging (box) for the personalized chocolate was designed in graphic design software CorelDraw.

Foil forming tool and finished holder

Custom designed box with holder

Results: In very short period of time a completely personalized box of chocolates has been designed and reproduced using advanced engineering technologies like 3D design and additive manufacturing.

Conclusion: Custom made products in food industry today maybe should occur through a departure from conventional approaches and traditional materials and designs. Application of Rapid Prototyping technologies in new product development as compared to the conventional approach, depending on the size of production can provide savings in the amount of 50 – 90% of used resources. Some disadvantages like high costs and limited choice of materials will probably be overcomed in future so the rapid prototyping technology will meet all the requirements set by production in the chocolate manufacturing industry.

Key words: personalized chocolate production, 3D design, rapid prototyping
