Revealed at the Solidworks World 2014 convention in San Diego in January, the Stratasys Objet500 Connex3 Colour Multi-material 3D Printer uses coloured plastic in the traditional inkjet colours of cyan, magenta, and yellow. It is the only 3D Printer that enables colour 3D printing with virtually unlimited combinations of rigid, flexible and transparent materials, as well as digital resources, in a single print run.
The 3D printer makes possible functionally complex models with desirable mechanical properties such as tensile strength, elongation before breaking, and multiple hardness values.
For example, the printer is able to print 3D glasses using an "opaque Veroyellow" material for the frame, a rubber-like black "Tangoblackplus" material and a translucent yellow tint for the lenses, all in one print job with no assembly required.
