Comparations of the 3D Printing Methods for the Production of the Reporting Medical Models

Abstract

The paper is focused on the area of manufacturing reporting medical models for verifications of custom made implants before the implantation. The CAD/CAM (computer-assisted design/computer-assisted manufacturing) trend of production of personalized implants supports the use of additive and subtractive production technologies with the creation of reporting medical models. The paper describes a geometrical comparison of four same patterns of the skull manufactured by different 3D printing technologies. It was realized actual-nominal comparison of CT scans of the medical models with CAD design of the skull as a reference. Deviations from the shape identified in our experiment, show the range from 1,89 mm to-0,91 mm.
