Prosilas and DUEPì join forces to revolutionize the production of silicone components.

The present article outlines a successful case study arising from the collaboration between Prosilas, a leading 3D printing company, and DUEPì Automazioni Srl, a company specializing in the design and manufacturing of industrial automation.

The shared objective? Harnessing the capabilities of 3D printing in PA2200 to create molds in short timeframes and at affordable costs, revolutionizing the production process of silicone components.

Silicone Components through 3D Printed Molds

The two companies collaborated on the production of molds in PA2200 using Selective Laser Sintering (SLS) technology.

The choice of PA2200 as the printing material was based on its excellent mechanical and chemical properties, combined with biocompatibility (certified according to EN ISO 10993-1 and USP/level VI/121°C).

Advantages for Mold Production

3D printing of molds in PA2200 offers a series of significant advantages compared to traditional technologies. Firstly, it allows for a drastic reduction in production costs, up to -180% compared to CNC machining or vacuum casting. This is achieved through the optimization of mold geometries and the reduction of material waste.

Secondly, 3D printing enables the production of molds in significantly shorter timeframes compared to traditional technologies. The speed of production allows for the creation of prototypes and finished products in a short time, ensuring greater flexibility and responsiveness to market needs.

Design flexibility and sustainability

3D printing in PA2200 provides extensive design freedom, allowing for the creation of complex and customized geometries. This results in molds optimized for specific applications, with the possibility of integrating various functionalities into a single mold.

Furthermore, 3D printing in PA2200 aligns with sustainability goals, thanks to the reduction of material waste and the production of lightweight and durable components.
