Development of natural models of human lungs by means of rapid prototyping

Abstract

The initial data were spiral-computer tomographic sections of the lung area, presented in the DICOM format. It should be noted that the thickness of the transition surface formed was chosen on the assumption that the volume would be reduced by 5 times. Using the FreeCAD software, the bracket was modeling in real physical dimensions, which combined into one model with the lungs. Next, the resulting model was loaded into specialized software MeshMixer. It allows you to perform various manipulations on three-dimensional models before printing. With its use, the model was dividing in a horizontal plane into five parts. After that, each part converted to G-code using a Cura slicer, and printed with PLA plastic on a 3D printer Wanhao Duplicator i3. Then the printed parts must be join together using a guide.
