3D printing has widespread applications in orthopaedics including creating biomodels, patient-specific instruments, implants, and developing bioprints. 3DGraphy or printing 3D models enable the surgeon to understand, plan, and simulate different procedures on it. Despite widespread applications in non-healthcare specialties, it has failed to gain traction in healthcare settings. This is perhaps due to perceived capital expenditure cost and the lack of knowledge and skill required to execute the process.
This article is written with an aim to provide step-by-step instructions for setting up a cost-efficient 3D printing laboratory in an institution or standalone radiology centre. The article with the help of video modules will explain the key process of segmentation, especially the technique of edge detection and thresholding which are the heart of 3D printing.
This is likely to enable the practising orthopaedician and radiologist to set up a 3D printing unit in their departments or even standalone radiology centres at minimal startup costs. This will enable maximal utilisation of this technology that is likely to bring about a paradigm shift in planning, simulation, and execution of complex surgeries.
3D打印在骨科领域有着广泛应用，包括创建生物模型、定制患者器械、植入物以及开发生物打印。3D成像或打印3D模型能让外科医生在模型上理解、规划并模拟不同手术过程。尽管3D打印在非医疗专业领域应用广泛，但在医疗环境中却未能得到广泛应用。这可能是由于人们认为其资本支出成本较高，以及执行该过程所需的知识和技能不足。
本文旨在为在机构或独立放射中心建立一个经济高效的3D打印实验室提供分步指导。借助视频模块，本文将解释分割的关键过程，特别是边缘检测和阈值处理技术，这些是3D打印的核心。
这可能会使执业骨科医生和放射科医生能够以最低的启动成本在其科室甚至独立放射中心建立3D打印单元。这将使这项技术得到最大程度的利用，有望在复杂手术的规划、模拟和执行方面带来范式转变。
