About 3D Printer For Implant Grade Silicone


Prayasta, incubated in IISc has developed 3D printer for implant-grade silicone for nasal, breast, airway stent and chin. Other uses would be calf, gluteal, orthopaedic insoles, orthotic linings, pectrol, etc. The company is gearing up for animal trails followed by human studies. The specialized 3D printer, Silimac, can directly 3D print implant-grade silicone material to make an implant within the hospital itself.


The company , set up by Vikas Garg and Shilpi Sen in 2017, was supported by grants from Department of Science & Technology, Biotechnology Industry Research Assistance Council, Ministry of MSME (MoMSME), Ministry of Electronics and Information Technology (MEITY), Start-up Karnataka and National Research development Corporation. Further it bagged the National Start-up Technology Award from Technology Development Board and was granted patents in India and USA.


3D printing allows personalization of implants on a one-to-one basis which not only improves outcomes of the surgeries but also reduces the average time spent for achieving the same results using standard implants, said Vikas Garg, co-founder, Prayasta.


As per Mr Garg, currently, Silicone is one of the best implantable materials. But conventional printers cannot handle implant-grade silicone because of its high viscosity. That is why, we have taken a fresh approach and developed a novel 3D printing technology from scratch, stated Garg.


Moreover 3D printed implants that are prepared using Silimac can be personalized not only in terms of shape, size, and contour but also in terms of weight, stiffness, touch and feel making it a complete solution.


The company has also developed a design methodology, ‘Novel Internal Architecture’ to make the breast implants rupture-proof and suturable eliminating the risk of leakage and post-implantation displacements respectively.


Along with IISc, the effort would be to propel the translation of personalized soft tissue implants from research to hospitals, to test the 3D printability of novel materials in a fast-track mode. We would also to develop the necessary skills for faster market reach of 3D printing technology, noted Garg.
