AUTOMATIC GEOMETRIC INSPECTION IN DIGITAL FABRICATION

Abstract. Additive Manufacturing in construction allows to create complex objects of different materials. Accordingly, an appropriate co-registration and comparison between the printed object its digital model is needed for several purposes: quality control (QC) ensure that tolerances are maintained realisation a twin which holds actual geometry. In this paper, we introduce automated robotic data capturing direct method. That is, terrestrial laser scanner (TLS) mounted on robot be moved freely printing room. addition, various strategies employed control. The also tripods, validate accuracy our solution. Furthermore, experiment real conducted two objects: shotcrete wax material object. Our experiments revealed there almost no influence position compared classical setup (mounting TLS tripod). when tripods 0.76 mm achieved by mounting 1.03 mm. From simulation it noticed C2M cannot detect missing extruded parts. To cope problem, used C2C M3C2 algorithms. For scenario, without edge trimming surface finishing challenging interpret directly. However, provided better results but requires parameters tuning. case finished algorithms have similar results.
