RESEARCH PROGRESS OF THREE-DIMENSIONAL PRINTING TECHNIQUE FOR SPINAL IMPLANTS

OBJECTIVE: To summarize the current research progress of three-dimensional (3D) printing technique for spinal implants manufacture. 方法: 检索查阅近年来国内外关于3D 打印技术应用于脊柱内植物的相关研究报道，对脊柱内植物的3D打印技术、打印材料、打印工艺、临床应用进行总结，并分析其不足及未来发展方向。. RESULTS: At present, 3D printing technologies used to manufacture spinal implants include selective laser sintering, selective laser melting, and electron beam melting. Titanium and its alloys are mainly used. 3D printing spinal implants manufactured by the above materials and technology have been successfully used in clinical. But the problems regarding safety, related complications, cost-benefit analysis, efficacy compared with traditional spinal implants, and the lack of relevant policies and regulations remain to be solved. 结论: 3D打印技术可为患者提供个体化定制的脊柱内植物，使脊柱外科手术更精准、更安全。随着3D打印技术和新材料技术的快速发展，更多的3D打印脊柱内植物将被研发并应用于临床。.
