One of the contributions of digital technology has undoubtedly been 3D printing. In order to make a 3D model, we need software that can manage and parameterise it for subsequent nesting and printing. The disappearance of the laboratory master model for the verification of structures means that this 3D printing option is undoubtedly becoming more and more in demand. Knowledge of these tools is vital to be able to carry out validation in both the clinic and the laboratory. We will present software that is fully adapted to the needs of the sector, with all the necessary features for the execution of 3D models, completely free of charge for the clinical/lab version and available to any user.
