In recent years, as a digital technology, 3D printing has the advantages of precision, customization, flexibility and speed, which is very in line with the advanced concepts of "precision medicine" and "digital medicine" and is widely used in the medical field. Especially in the application scenarios of orthopedic and rehabilitation aids, customized scoliosis orthoses printed by SLS laser sintering technology have begun to be used by more and more patients.

Traditional orthoses are generally made by plaster molding, trimming, thermoplastic board attaching, cutting, sanding, and installation of lined cable ties. The whole process is relatively cumbersome, and the whole process of gypsum taking requires the participation and cooperation of patients, the patient experience is not good, and the production efficiency is low. In addition, traditional orthoses are large in size and difficult to hide, which has a relatively large impact on the normal learning and life of adolescents.

Compared with the traditional production process, TPM3D uses 3D scanning technology and professional software to design its own accurate customized orthosis model for each patient, and then uses TPM3D industrial-grade SLS nylon powder <>D printing equipment to mass produce these orthoses, and finally after chemical steam smoothing treatment to obtain the finished product, the treated product surface is smooth and beautiful, the toughness is excellent, and waterproof and antibacterial, which can meet the long-term wear and use of patients. At the same time, the entire production process is greatly simplified.

SLS 3D printed scoliosis orthoses offer the same therapeutic effect as traditional thermoplastic panels while improving production efficiency. The application of this technology makes the application scenario of "mass customized production of scoliosis aligners" a reality, and at the same time improves the patient's modeling experience and treatment experience, and the orthoses manufactured are lighter, more beautiful, more fitted, and easy to hide. Minimized impact on adolescents' daily lives.

Shanghai TPM3D 3D Printing Technology Co., Ltd. continues sls industrial printer in china to pay attention to the application and promotion of SLS 3D printing technology in the medical field, and cooperates with the School of Medical Transformation of Shanghai Jiao Tong University and Zhongshan Chen Xinghai Hospital to jointly establish the "Chen Xinghai Hospital <>D Printing Application Center" in Zhongshan, Guangdong, relying on TPM3D's laser sintering <>D printing technology to manufacture customized health care and rehabilitation products and provide precision medical solutions for patients. At present, the orthopedic application and rehabilitation application departments are mainly set up. The application scenarios selected for this list come from this center.

Since the completion of the center, it has completed the design, manufacture and application of a variety of 3D printed orthopedic and rehabilitation products, with a total of more than 3 cases, including 3D printed TPU orthopedic insoles, TPU orthopedic headrests, ankle and foot orthoses, knee orthoses, scoliosis orthoses, wrist braces, elbow braces, etc., which have been favored and praised by patients and families. At the same time, we also hope to cooperate with more hospitals and patients to provide a complete set of orthopedic rehabilitation solutions including technical services, design services, customized products and software and hardware, use SLS 3D printing technology china sls 3d printer to solve patients' problems, and jointly promote the application of <>D printing technology in the medical field with hospitals to promote the development of digital medicine and precision medicine.
