Tangshan Weihao Showcases Biodegradable Magnesium Alloy for 3D Printed Orthopedic and Dental Implants at Suzhou Conference

Tangshan Weihao presented its latest developments in biodegradable magnesium alloy for 3D printed orthopedic and dental implants at the Suzhou conference. By combining alloy design, surface modification, and structural optimization, the company aims to balance degradation rate and mechanical performance. This approach provides new opportunities for personalized medical devices and advanced biomaterials.

From March 24–25, 2026, the COD 2026 Orthopedic Implant Conference and the 2nd 3D Printing Technology Application Conference were held in Suzhou. Tangshan Weihao Magnesium Powder Co., Ltd. participated and presented its latest work on biodegradable magnesium alloy for additive manufacturing in orthopedic and dental implants.

Biodegradable Magnesium Alloy for Medical Implants

In orthopedic and dental applications, conventional materials present challenges:

Titanium implants often require secondary removal surgery
Polymer materials have limited mechanical strength

Magnesium alloys offer an alternative due to:

Density close to human bone (1.74–1.84 g/cm³)
Elastic modulus similar to bone (41–45 GPa)
Gradual biodegradation in the human body
Magnesium ions supporting bone regeneration

These features make magnesium alloys relevant for biodegradable implant materials and biomedical metal applications.

Additive Manufacturing Enables Complex Structures

Due to high reactivity, magnesium alloys are difficult to process using traditional methods.
Selective Laser Melting (SLM) and other additive manufacturing technologies enable:

Porous bone-like structures
Customized implants
Precise geometry control

Tangshan Weihao leverages its experience in spherical magnesium powder production and particle size control to support stable additive manufacturing processes.

Addressing Key Challenges in Magnesium Alloys

To manage degradation and hydrogen evolution, the company adopts a systematic approach:

Alloy design: optimizing corrosion behavior using rare earth elements
Surface modification: improving early-stage stability
Structural design: balancing mechanical support and degradation rate

Future Outlook

Emerging trends in this field include:

Patient-specific implant design
4D printing and controlled degradation
Drug-loaded functional implants

Tangshan Weihao continues to explore the integration of magnesium alloy powders and additive manufacturing technologies for medical applications.
