In addition to representing the anatomic form, the 3D printing technology also provides various physical properties to support the specific requirements of implants, orthotics, braces and prostheses via materials or structures that are built by manual or computational design. The 3D scanning technique prevents patient discomfort and induces less distortion of the target region. Moreover, non-contact scanners based on a laser source and depth camera have become an option to replace the use of a conventional physical casting to acquire the anatomic surfaces necessary for the fabrication of orthoses or prosthetics. CT or MRI anatomic imaging techniques can capture volumetric images of bones and soft tissues, and these images can be materialized by 3D printing devices as physical models to aid surgical planning or training. Integration of 3D printing and medical image capturing technologies has been widely applied in medicine.

The results from the design exercise accurately reflect real-world situations in which an inexperienced user utilizes a generator as well as demonstrate the utility of the parametric model approach and strategy for training and interfacing. The parametric model reduced the complex process of orthosis design to a few minutes, and a customized interface and training program accelerated the learning period. ConclusionsД¬ompared to manual modeling instruction, this study highlighted the feasibility of using a parametric model for the design of 3DвЂ“printed orthoses and its greater ease of use for medical personnel compared to the CAD technique. The few faults and program errors that were observed in video analysis of the exercise showed improvable weaknesses caused by the scanning quality and modeling process. They verified its feasibility in an orthosis design exercise and designed 5 orthoses without assistance within 8 to 20 mins. A quick training program was formulated, and 5 participants from a nursing school completed the training within 15 mins.

ResultsДЄ set of automatic steps for orthosis modeling was developed as a parametric model using the Visual Programming Language in the CAD environment, and its interface and workflow were simplified to reduce the training period.

The purpose of this study is to develop a parametric model as the design generator for 3DвЂ“printed orthoses for an inexperienced CAD user and to evaluate its feasibility and ease of use via a training and design exercise. This skill gap limits clinicians from applying this technology in fracture treatment. Currently, the design of such orthoses is most often performed in the CAD environment, but creating the orthosis model is a time-consuming process that requires significant CAD experience. Applying 3D printing technology for the fabrication of custom-made orthoses provides significant advantages, including increased ventilation and lighter weights.
