Scientists from Tomsk Polytechnic University (TPU), together with international colleagues, have created a technology to improve the biomechanical properties of titanium alloys obtained by electron-beam 3D printing. These materials can be used to create custom bone implants, which will increase their durability and improve the quality of life for patients. This was reported in the press service of the Ministry of Education and Science of Russia.
The difference in mechanical characteristics creates difficulties in integrating such titanium alloys into medical practice. For example, an implant made of such material may take on the main load, while the surrounding bone tissue will begin to degrade. Therefore, there is a need to bring the elasticity of the artificial material closer to the elasticity of bone tissue.
According to her, the scientists created a material by fusing titanium and niobium. Then they turned it into a powder for further research. This made it possible to avoid the heterogeneity that previously arose when using elemental powders. The problem was the different melting points of titanium and niobium.
The study showed that by changing the printing parameters, it is possible to control the internal structure and properties of the alloy while maintaining its chemical composition. This discovery opens up new horizons for creating personalized implants with the desired characteristics.
Earlier, oncologists at Sechenov University began using 3D modeling of mammary glands before surgery. This innovative method significantly improves the accuracy of surgical interventions. The technology is based on 3D scanning. It creates a digital model of the patient's body. This allows surgeons to plan the operation in advance and visualize its result.
