Non-contact 3D digitizing scanners based in structured light projection are increasingly more accurate, fastest and affordable. The purpose of this work was to determine the quality, accuracy and traceability of the data provided by new LED technology scanner of structured light Comet L3D (Steinbichler) acquired by the Department. Calibration of the equipment and accuracy analysis was carried out with a calibration plate and a number of gauge blocks of different sizes. The accuracy range of the scanner has been established through multiple digitizations showing the dependence on influential factors such as the characteristics of the object and scanning procedure. Although many factors influence, accuracies announced by manufacturer have been achieved under optimal conditions and it has been noted that the quality of the point clouds (density, noise, dispersion of points) provided by Comet L3D system is higher than that obtained with laser technology devices
