Technical features: Tantalum has characteristics such as a high melting point and high density, making traditional processing methods rather difficult. Additive manufacturing technology manufactures tantalum components by layering materials without the need for molds, enabling precise manufacturing of complex shapes and structures. For instance, laser powder bed melting technology can use high-energy laser beams to melt tantalum powder and stack it layer by layer according to a preset three-dimensional model, forming tantalum products with specific shapes and properties.
In the medical field, tantalum has excellent biocompatibility, bone conductivity and other advantages, making it an ideal material for orthopedic implants. 3D printing can produce personalized and customized porous tantalum implants that match the porous structure and mechanical properties of the patient's bone defect area, such as hip and knee joint pads, femoral head necrosis reconstruction rods, and hip joint acetabular cups. For instance, has broken through the key preparation technology of laser 3D printing bionic trabecular bone porous tantalum. The comprehensive mechanical properties of the porous tantalum it prints lie between cancellous bone and cortical bone in the human body, which is conducive to the growth of bone tissue and blood vessels. In addition, medical has developed the first domestic tantalum metal additive manufacturing intervertebral fusion device and achieved personalized customization, which has increased the fusion rate with bone cells and blood vessels, and contributed to precision medicine.
In the aerospace field, refractory metal alloys such as tantalum and tungsten are ideal materials for manufacturing high-temperature components. 3D printing technology can produce tantalum alloy components with complex cooling channels and lightweight structures, which are used in key parts of aero engines such as combustion chambers and exhaust pipes, improving the performance and reliability of the components.
In the field of consumer electronics, tantalum has advantages such as high capacitance density and good stability, and is widely used in various electronic devices. 3D printing technology can achieve the miniaturization and integrated manufacturing of tantalum electronic components, enhancing the performance and reliability of electronic devices.
