Diseño y construcción de un escáner 3D e integración en una impresora 3D

Abstract

This system has a 3D scanner based on laser triangulation, integrated to a 3D printer based on fused deposition modeling. The same printer hardware and firmware has been used to integrate the peripherals of the scanner: (2) lasers and (1) rotating platform; the camera connects directly to a computer that has software developed to handle the functionalities of the scanner, which obtains a point cloud, and due to integration of external tools of postprocessing (surface reconstruction using meshlab) and laminate (g-code using slic3r) that run in the background, a file is automatically generated ready for interpretation in the 3D printer, closing the reproduction cycle of a model. Due to its low cost and open source, this prototype make accessible performing reverse engineer of an object by means of digital acquisition (3D scanner) and its reproduction (3D printing) in only one equipment.
