In recent years, the application of 3d printing technology in the field of medicine has made remarkable progress, 3d printing of medical surgical guides, surgical models and implantation implants are mainly used for orthopedic, oncology, oral, hepatobiliary, urology and so on a dozen departments.
Advantages of 3d printing
Traditional product design is completed by 3d printing, and does not give full play to the true value of 3d printing. In more cases, it is necessary to break through the limitations of design thinking and give full play to the free modeling advantages of 3d printing. 3d printing also has the advantages of personalized customization, complex geometric shapes, and functional integration
Exclusive customization
Mentioned earlier, in the field of biomedicine, there is a need for customized biomaterials to assist in the treatment of the needs of the case that are more in line with the needs of the case. 3d printing technology can be used to print a customized biomaterial that meets the requirements of the case through the 3d The accurate data from 3d scanner can print out the products which are highly matched with the patient's needs, so that it can get the most suitable products in the shortest time and help it to recover the health as soon as possible. 3d printing applied to personalized customization cases include: medical models, bionic ears, tissue organs, implants, hearing aid shells and so on.
Complex geometry
3d printing can model complex geometric objects, combined with existing two-dimensional data, to obtain scientifically accurate models of the patient's lesions, providing accurate guidance for the doctor's surgical treatment.
Implants
Implementation of the composite structure: the porous structure of the implant, strong, with enough space for elastic deformation, conducive to bone growth. Due to the complex shape and small size of the pore structure, it can not be realized by traditional machining process. Metal 3d printing technology can manufacture the implant according to the porosity and size in the design plan, bringing a higher degree of freedom to the design optimization of the implant.
Functional integration
The spacer used in spinal reconstruction surgery is made by three-dimensional printing technology, the product design adopts the hegemonic design concept, which can be adjusted according to the patient's anatomical condition and the doctor's requirements, and at the same time, as a reinforcing cushion to the spinal cord, the manufacturing highlights are completed at one time through the metal 3d printing technology, which eliminates the step of disassembling the product for assembly.
The above examples are proof of the prospects for the development of 3d printing in the medical industry and the value of the embodiment of 3d printing in various fields of application still has obvious advantages, Zongwei cubic and we look forward to the further development of this technology.
