MINNETONKA, MN and REHOVOT, Israel, July 15, 2025 – Stratasys has launched P3 Silicone 25A, a 3D-printable material developed with Shin-Etsu for the Origin DLP platform. Designed for flexible part production without tooling, it offers mechanical and thermal properties similar to molded silicone. The material has been validated for thermal aging up to 1,000 hours at 150°C and meets biocompatibility and flame-retardancy standards.
The new material addresses a gap in industrial 3D printing for precision silicone parts that are durable and consistent, without the lead times and cost constraints of injection molding. P3 Silicone 25A provides chemical resistance, thermal stability, and mechanical properties similar to traditional silicones. It allows manufacturers to avoid tooling, shorten lead times, and support local, low-volume manufacturing. The material has passed thermal aging tests at 150°C for up to 1,000 hours and meets biocompatibility and flame retardancy standards.
Manufacturers are using silicone for parts such as seals, gaskets, vibration dampers, wearables, and soft-touch components, as they work to customize products, manage inventory, and reduce time to market. However, 3D printing materials have not matched the performance of molded silicone. P3 Silicone 25A combines Stratasys’ P3 DLP technology with Shin-Etsu’s silicone chemistry to provide a solution for producing silicone parts.
“The proliferation of additive manufacturing in production environments depends on specialty materials that perform to the standards of traditional methods,” said Rich Garrity, chief business unit officer, Stratasys. “Our collaboration with Shin-Etsu delivers precisely that. P3 Silicone 25A gives manufacturers the flexibility of additive with the trusted performance of true silicone – backed by repeatable results and real-world data.”
The launch marks the first in a portfolio of silicone materials co-developed by Stratasys and Shin-Etsu, with hardness levels and application-specific variants expected in the future.
“We are excited and proud to be working with Stratasys, the global leader in additive manufacturing, to bring 3D printable true silicone to market and grow together,” said Makoto Ohara, head of sales and marketing department S4, Shin-Etsu Silicones Europe B.V. “P3 Silicone 25A combines excellent physical properties and long-term reliability with detailed and precise printability. It can rightly be considered ‘true silicone’ in both composition and performance.”
