EN In recent years, many studies have focused on CAD/CAM systems for the design and manufacture of orthopaedic corsets for scoliosis. The rapidly growing field of 3D printing offers unique opportunities in biomedical applications, with benefits arising from the ability to customise the shape to the patient's body, and relatively low manufacturing costs. Currently, the goal is to minimise corset design in terms of both mass and volume of material used, while maintaining it's full corrective functionality. In addition, attention is also paid to aesthetic aspects. The use of 3D printing technology makes possible to develop an individually adjusted, lighter and more comfortable orthopaedic corset. This paper presents the results of FEM structural analyses carried out for two types of corsets: a standard full structure and a corset with 3D grid pattern structure. The analysis is a demonstration of the possibility of using pattern grid (many small holes) on the surface of the corset. Additionally, the influence of forces generated by the tension of fixing tapes on the corset model was examined.
