Product Introduction
Sector demand
1.New material
Developing novel materials with enhanced implantable value requires meticulous consideration of key properties, including biocompatibility, biodegradability, and shape-memory effects.
2.personalized customization
The fabrication of implants with a high degree of congruence to both the individual characteristics of the patient and the specific pathological site represents a significant clinical challenge. Conventional subtractive manufacturing techniques, such as milling-based approaches, struggle to achieve such precise and customized alignment.
3.bionic structure
The implant material must exhibit weight and elastic modulus properties comparable to human bone. Specific regions of the implant should possess a trabecular bone-like microstructure to facilitate osteogenic induction and promote bone cell proliferation.
4.volume production
Implants must be amenable to stable mass production, with productivity meeting the requirements for market release. The mechanical properties of the materials used in mass production must demonstrate high levels of stability and consistency.

3.personalized customization
- Leveraging patient-specific medical imaging data, a customized three-dimensional implant model is generated through CAD-based parametric modeling and structural optimization design.
- The physical prosthesis is subsequently fabricated via additive manufacturing, where the dimensional accuracy of 3D printing ensures full geometric fidelity to the digital model, thereby satisfying the requirements for personalized medical device customization.
- Based on the patient's medical imaging data, a three-dimensional implant model customized to individual anatomical characteristics is generated through computer-aided design (CAD) modeling and structural optimization.
- The utilization of 3D printing technology enables the fabrication of physical objects, wherein the dimensional accuracy of the printed constructs allows for a full-scale reproduction of the three-dimensional implant model, thereby meeting the requirements for personalized customization.
4.Biomimetic Structures (Porous Architectures)
- Minimum rod diameter: 0.1 mm, aperture diameter: 200–400 µm.
- The geometric configuration and porosity of the porous structure can be custom-designed to achieve high congruity with the trabecular bone architecture.
- Mechanical Compatibility: In contrast to dense metallic materials, porous structures exhibit a significantly reduced elastic modulus, which aligns more closely with that of human bone. This characteristic effectively mitigates stress shielding effects, prevents bone resorption following implantation, and enhances the mechanical compatibility between the implant and the host bone.
- Tissue Compatibility: The porous structure, which more closely resembles the trabecular bone architecture, promotes the growth of human bone cells, thereby enhancing the tissue compatibility between the implant and the host bone.
5.volume production
- Customized process parameters tailored to the characteristics and application requirements of medical products yield superior product quality, improved surface roughness, and enhanced forming efficiency.
- High uniformity and consistency: Demonstrated conformity through isotropic analysis, cross-regional assessments of the same format, and multi-batch validations, meeting the requirements for mass production.
Our M260 metal 3D printer is equipped with a dual-laser system, which enhances production efficiency by 60% to 70% compared to single-laser forming equipment.
