Stratasys announces the market launch of P3 Silicone 25A. This is a high-performance polymer developed with Shin-Etsu, an expert in silicone materials, for additive manufacturing.

The 3D printing expert Stratasys and silicone specialist Shin-Etsu have developed a printable silicone that gives additively manufactured components the same properties as injection-molded parts. Here is an example of its application.

The universally applicable silicone P3 Silicone 25A was reportedly developed exclusively for Stratasys's Origin DLP platform. And as manufacturers increasingly individualize products, optimize inventories, and shorten time-to-market, silicone has become indispensable for applications such as seals, O-rings, vibration dampers, wearables, and "soft touch" components. The newly developed silicone enables the production of flexible components that achieve the performance of traditionally molded silicone, as Stratasys emphasizes. The new material also addresses a long-standing gap in industrial 3D printing—specifically, the demand for genuine silicone parts that offer precision, durability, and repeatability without the time and cost disadvantages of injection molding and associated tooling efforts.

Silicone Innovation Advances 3D Printing

P3 Silicone 25A is also on par with conventional silicones in terms of chemical, thermal (tests confirmed 1,000 hours at 302 °F ), and mechanical properties. Switching from injection molding to 3D printing silicone with this material also promises shorter lead times and local production (even in small quantities). In addition to the mentioned properties, it boasts certified biocompatibility and flame-retardant effects. According to Stratasys, this represents another step toward greater adoption of additive manufacturing in the industry. Furthermore, the material is just the first outcome to be expected from the collaboration with Shin-Etsu. P3 Silicone 25A is currently available in EMEA and APAC and will be introduced to the Americas later this year.
