BSSE partners with Prayasta to create the first 3D printer for implant-grade silicone

The 3D printer developed by Prayasta has been named Silimac P250, the world’s first 3D printer to manufacture medical grade silicone implants. The startup has also developed its key technology – iEAM

The Center for Biosystems Science and Engineering (BSSE) at the Indian Institute of Science (IISc) in Bengaluru has collaborated with a startup Prayasta to develop a state-of-the-art 3D printer capable of 3D printing silicone from medical implant quality.

Prayasta developed this 3D printer in-house with support grants from various government agencies including Nidhi Praya (Government of India’s Department of Science and Technology), Biotech Ignition Grant (Biotechnology Industry Research Assistance Council), Design Clinic Scheme (MSME Center of Excellence Indian Institute of Science Bangalore), Tide 2.0 Meity Startup Hub (Ministry of Electronics and Information Technology), Elevate Call 2 Startup Karnataka (Department of Electronics, IT, BT, S&T).

Conventional 3D printer cannot use implant-grade silicone to make silicone medical implants because traditional 3D printers use either filament or powder material.

The natural form of “implant-grade” silicone is a liquid (high viscosity) and cannot be converted to filament or powder. Therefore, conventional 3D printers cannot use “implant-grade” silicone.

Silimac P250 can be used for custom implants and prostheses for all soft tissues including breast, nose, chin, ear, lip, trachea, food tube, calf, pectoral, etc. .

This is an industrial grade machine that operates reliably and uninterrupted for long hours of production. It can hold up to 14,000ml of silicone in a single refill and is ready for large scale production.

Silimac P250 has built-in UV sterilization for the print chamber and a contamination-free support system. The implants manufactured by Silimac P250 are based on a new internal architecture design (NIA) methodology, which makes the implants fracture resistant with a reduced risk of post-implantation displacement. The implants made by this 3D printer are customized and balanced in weight.

Custom shapes and sizes with perfectly symmetrical appearances lead to more confidence and less anxiety in personal, professional and social environments.

Additionally, Silimac P250 can be directly installed in hospitals offering facilities to manufacture custom silicone implants within the hospital.

Shilpi Sen, CEO and co-founder of Prayasta, said animal trials followed by human trials of Silimac P250 would begin soon.

Prayasta was also awarded the Technology Startup Awards 2022 by the Government of India’s Department of Science and Technology (DST), on National Technology Day 2022 for developing indigenous technology with commercialization potential.
