Vasantham Seithi: Prosthetic Arm – New Hope for Singapore’s Healthcare
Vasantham channel’s Seithi (news) programme interviewed Assistant Prof Subburaj Karupppasamy and Tan Tock Seng Hospital’s Principal Prosthetist Trevor Binedell on their research collaboration to fabricate a non-metallic, self-locking 3D printed prosthetic arm for a patient. It is also 20% cheaper compared to conventional ones in the market. Trevor is also currently an EPD PhD student at SUTD.

Channel 8, Tan Tock Seng Hospital and SUTD collaborate to 3D-print more comfortable and flexible prostheses
Channel 8, Tan Tock Seng Hospital and SUTD collaborate to 3D-print more comfortable and flexible prostheses Channel 8 News did a feature on the SUTD and Tan Tock Seng Hospital collaboration to print 3D-printed more comfortable and flexible prostheses, featuring interviews with Eric Teh, NAMIC’s senior centre manager and Trevor Binedall, TTSH’s principal prosthetist and an EPD PhD student.
