Optimizing FDM 3D Printing of Medical Models

Abstract

Present paper presents the results on four cases of optimization of FDM 3D printing of medical models used for training on specific medical issues (2 cases) and of personalized patient-specific models used for complex Trauma and Orthopedic surgical procedures planning (2 cases). Depending on optimization criteria (proper combination of model splitting – minimum need of supports/or no supports – minimization of printing time and material consumption, facile support removal and good surface quality), the modification of the Cura slicer recommended settings related to layer thickness and support pattern, support Z distance, support X/Y distance, support overhang angle, and minimum support area, allowed the reduction of 3D printing time with 24% and 33%, very easy support removal, and an assessment of surface accuracy and quality as very good for the purpose, made by end users.
