| Abstract: |
Process intermittent measurements of parts fabricated by additive manufacturing (AM) can enable both in-process improvement and characterization of parts' internal geometries. The planar, layer-upon-layer nature of most AM processes allows simple two-dimensional measurements because the part's current layer is continually in focus for a calibrated vision system. Proof of this concept has been shown through measurement of parts made using a three-dimensional (3D) printer. Process intermittent measurements were compared to contact and non-contact measurements of the finished parts to characterize deviations in printed layer positions, along with changes in part dimensions resulting from post-process treatments. |
