Dow Corning Develops Printable Silicone Rubber
Auburn, MI — Dow Corning has developed a 3D-printable silicone rubber, LC-3335, in collaboration with German RepRap GmbH, a man- ufacturer of fused filament fabrica- tion (FFF) 3D printers. The new material is the first Dow Corning product formulated specifically for designers seeking to combine the performance benefits of silicone with the design and processing advan- tages of additive manufacturing. The company created the material to offer customers a way to make use of the beneficial properties of silicone in fast prototype development and small series production of highly complex parts. German RepRap designed its
RoHS
patent-pending 3D printer to print successive layers of LC-3335 in a method comparable to the FFF process. It can form complex silicone parts that would be difficult or impossible to achieve through con- ventional injection molding. Each layer of silicone is fully cross-linked through thermal cure to enable parts with mechanical properties that are similar to molded components. Test parts printed with LC-
3335 silicone exhibit the same sharp cure profile of injection molded test samples, as well as around 80 per- cent of the samples’ mechanical prop- erties. Specifically, 3D printed parts
demonstrate 70 percent of the tensile strength elongation of injection molded samples, and 90 percent of
their tear strength. With German RepRap’s platform, LC-3335 is potentially capable of printing func- tional prototypes and enabling small manufacturing trials of complex parts. Further, the material’s proper- ties closely match those of liquid sili- cone rubber (LSR), allowing an easy transfer into injection molding processes for high-volume manufac- turing. Additive manufacturing prom-
ises to accelerate the design-to-pro- duction process by quickly converting digital designs into functional parts for low- to medium-volume manufac- turing without the time or cost required to first build a molding tool and prototype. Consequently, the technology can significantly reduce production waste, optimize the sup- ply chain, eliminate tooling and speed the time to market for new designs unachievable through con- ventional technology. LC-3555 silicone
expands
design options in automotive, health- care, cookware, lighting and other applications where traditional LSRs are used. Dow Corning is currently exploring future silicone rubber products for 3D printing, including optical- and medical-quality grades, UV-curable materials and other solu-
tions. Contact: Dow Corning, 2200 W
