Background
In 2023, China’s medical additive manufacturing sector witnessed two major milestones. A medical company (hereafter referred to as “the Company”) leveraged ChanHonTech’s metal 3D printing solutions to develop its first titanium additive-manufactured intervertebral fusion device, successfully obtaining the country’s first Class III medical device registration for a bionic trabecular bone structure using titanium powder. On November 30, the Company again used ChanHonTech’s core technology to develop a porous titanium hip joint filler, which also received Class III medical device registration.
These two products not only filled a gap in the domestic market for porous titanium additive manufacturing but also marked a leap from “catching up” to “leading” in high-end medical metal 3D printing technology in China, contributing to global precision and personalized healthcare.
Challenges
The spine and hip joint, key support structures of the human musculoskeletal system, are notoriously difficult to repair in orthopedics. Traditional implants often face challenges such as insufficient biocompatibility, mechanical mismatch with human bone, low fusion rates, post-operative pain, and loosening of devices. The Company needed a solution capable of producing orthopedic implants with both high precision and biocompatibility, while also enabling rapid and reliable manufacturing.
ChanHonTech’s Solution
The Company adopted ChanHonTech’s metal 3D printing technology to develop two titanium medical devices, addressing key industry pain points and achieving “bio-mimetic fit” and “efficient repair” in orthopedic implants. ChanHonTech’s equipment offers core advantages in design flexibility, printing precision, and material control, allowing the Company to rapidly manufacture and validate complex medical device components.
Key benefits include:
- High-Precision Manufacturing: ChanHonTech’s metal 3D printing technology supports complex pores, multi-porous structures, and fine surface features, ensuring high compatibility with human bone.
- Reduced Lead Time: Compared to traditional metal manufacturing, 3D printing dramatically shortens part production times, allowing the Company to complete prototype validation and small-batch production within days.
- Improved Surgical Outcomes: The high-precision, bio-mimetic titanium implants enhance bone fusion rates, reduce post-operative complications, and improve overall patient outcomes.
Results and Industry Impact
With ChanHonTech’s metal 3D printing technology, the Company achieved:
- Accelerated Product Development: The development cycle for the titanium intervertebral fusion device was shortened by 50%, and the porous titanium hip joint filler was rapidly brought into small-batch production.
- High Precision and Reliability: Printed parts passed rigorous surface quality testing, ensuring optimal bone compatibility and significantly improving implant success rates.
Industry Advancement: ChanHonTech technology enabled the Company to transition from traditional manufacturing to high-end additive manufacturing, setting a benchmark for the domestic medical 3D printing industry.
Comparison: Traditional Manufacturing vs. ChanHonTech
Compared to conventional CNC machining and mold-casting processes, ChanHonTech’s metal 3D printing offers clear advantages:
- Flexibility: Supports complex geometries and personalized customization, which are difficult or impossible with traditional methods.
- Production Speed: Traditional manufacturing cycles are long, whereas ChanHonTech can produce complex parts within days.
- Material and Precision Control: Traditional processes struggle to achieve high porosity and precise structures; 3D printing ensures both mechanical performance and biocompatibility.
Conclusion
ChanHonTech’s metal 3D printing technology provides the Company with a full-chain solution from R&D and validation to small-batch production. Through the successful development of these two titanium devices, the Company has achieved high-precision, high-efficiency additive manufacturing breakthroughs, advancing the domestic high-end medical 3D printing industry and supporting the growth of precision and personalized healthcare.
