Título del libro: Proceedings - Aspe 2015 Spring Topical Meeting: Achieving Precision Tolerances In Additive Manufacturing Título del capítulo: Model - Support material interaction inspection by X-ray computed tomography in FDM additive manufacturing process
Additive Manufacturing (AM) is a layer-based automated fabrication process for making 3-dimensional physical objects directly from 3DCAD data without using part-depending tools. Material extrusion systems represent the largest installed base of AM machines. Fused Deposition Modeling (FDM) is a material extrusion process in which model material is selectively dispensed through a nozzle tip or orifice. According to the geometry, manufacturing orientation, material and building strategy, the devices produced by FDM technology would require a second nozzle tip that extrudes another thermoplastic support material to allow the upper model material to be located [1,2]. The authors, studied the surface and inner structure of parts produced by AM FDM technology and detected possible material or manufacturing defects as a consecuense of model and support material interaction by means of an X-ray CT system. The studied material was polycabonate (PC). The machine used for the test was a Stratasys Fortus 400 with T16 nozzle tip and PC-S support material.
