Multiple modulus silicone elastomers using 3D extrusion printing of low viscosity inks

Silicone elastomers are of commercial interest in a number of areas because of their distinctive properties. Current 3D-printing (additive manufacturing) technologies for silicones mainly rely on the extrusion of high-viscosity pre-elastomer inks of one or two parts. Some of the challenges presented by high viscosity materials, for instance, difficulties in mixing and changing inks to create devices from more than one type of silicone, could be …
