Abstract

The use of 3D printing is a technology in increasing expansion in the area of the medical sciences. We describe it the technical characteristics of 3D printing and a protocol of obtaining of models three dimensional as a complement to the imaging studies for the approach of complex injuries. 3D printing of five areas of interest corresponding to vascular lesions, spinal, renal and pulmonary by additive manufacturing technique. 1.75mm extrafill polylactic acid was used, following the imaging method DICOM medical, 3D reconstruction in format STL and G-code of each structure, being carried out Ender-3 computer printing. They were printed structures at a scale of 50-75% of the real volume, with average processing time of 32.4 min. This technology allows you to individualize care of patients with complex injuries, raising the quality of medical services, techers and decreasing the direct costs of care per hospital stay.
