Being able to provide patients with prostheses fitted exactly to their anatomy or create precise models for surgical planning. These are just some of the ways Dr Michael Yam is transforming healthcare through 3D printing technology. An innovative champion for Medical 3D Printing (Med3DP), he has harnessed 3DP to revolutionise clinical care, enhance medical education, and drive institutional efficiencies. 

The First 3D Printing Centre in NHG

Since establishing the Tan Tock Seng Hospital’s Medical 3D Printing Centre in 2022, Dr Yam has guided its growth and expanded its services to 17 subspecialties across 5 hospitals, delivering 5 new direct patient services, and benefiting 200-250 patients annually with personalised solutions. 

Under his guidance as Clinical Director, the Centre has expanded its capabilities, developing ISO-aligned regulatory processes and risk management frameworks, paving the way for widespread 3DP implementation on a national level, while setting benchmarks for quality and safety. 

His forward-thinking approach leverages cutting-edge technologies such as AI, Mixed Reality, and advanced 3D-printers to innovate and strengthen the Centre’s capabilities. These advancements reduce operating theatre time, save costs, and increase patient satisfaction.

Creating the C4 (not the explosive!)

The Completely Customised Cranial Cap (C4) was co-developed with rehab physicians, neurosurgeons, and occupational therapists. Unlike conventional caps, C4 fits the patient's exact cranial defect providing comfort and improved fit, increasing compliance and safety during rehabilitation. This patented innovation, which addresses the shortcomings of mass-produced alternatives is currently provided to craniectomy patients in the cluster.

Dr Yam plans to launch a precision surgical 3DP translation program to accelerate idea-to-market and clinical implementation process, circumventing the common validation gap for 3DP devices. In preparation, he established rigorous regulatory processes, risk registers and risk management frameworks aligned with ISO regulatory standards, paving the way for national implementation, while setting quality and safety benchmarks. Furthermore, he formed national 3DP workgroups to drive focused efforts that are clinically, scientifically, and commercially viable.

Beyond clinical applications, Dr Yam is instrumental in fostering the growth of the local 3DP ecosystem. He supports local startups by providing clinical insights that drive development, contributing to successful fundraising; as well as international collaborations that attract resources and investments.

4D Printing and More

Looking ahead, Dr Yam continues to explore new possibilities in the field. His work with startups like Castomize is advancing 4D-printed orthopaedic casts, while his partnership with Zeda focuses on developing 3D printed metal implants. These collaborations, along with partnerships with companies like Mitsui Chemicals, are bringing advanced materials and cutting-edge technologies to Singapore’s healthcare sector. 

Recently recognised with the Exemplary Innovator Award at the Public Sector Transformation Awards 2025, Dr Yam's contributions demonstrate how medical expertise, and technology can work together to enhance patient care. Through his leadership, the TTSH Medical 3D Printing Centre has become an innovation hub that is actively shaping the future of healthcare delivery in Singapore.
