The dual-jet process can combine materials in several ways, enabling the simultaneous use of two different rigid materials, two flexible materials, one of each type, any combination with transparent material, or two jets of the same material. Two perfectly synchronized printing heads are designated for each material, including the support material. Connex printing systems can produce prototypes that possess properties that mimic traditional elastomeric materials including EPDM and NBR. This means you can evaluate a design that incorporates soft touch areas. Several rubber–like materials with different shore values can be printed at the same time and evaluated on the design model. The model can then be tested on a focus group as well as on potential customers to be able to measure how comfortable and easy to use the product is. Issues such as a product’s impact resistance can also be evaluated.
