System Performance and Process Capability in Additive Manufacturing: Quality Control for Polymer Jetting

Abstract: Polymer-based additive manufacturing (AM) gathers a great deal of interest with regard to standardization and implementation in mass production. A new methodology for the system and process capabilities analysis in additive manufacturing, using statistical quality tools for production management, is proposed. A large sample of small specimens of circular shape was manufactured of photopolymer resins using polymer jetting (PolyJet) technology. Two critical geometrical features of the specimen were investigated.… Show more

“…If this was the case, factor-dependent distortion models should be applied to each combination of significant factors. Since the contact between the model material and the support material causes matte finish, glossy cylindrical surfaces can only be manufactured unsupported (with the cylinder axis parallel to the Z axis) [ 5 ]. Accordingly, within the limits of the proposed example, part location in the manufacturing tray was the only processing decision left to be included in the analysis of model extension.…”

“…Some research studies [ 4 , 5 , 6 ] were focused on characterizing the process capability from a metrological point of view. Different approaches range from using a gage repeatability and reproducibility (G&R) methodology for the capacity evaluation of a polymer jetting system [ 5 ], to benchmarking comparisons of dimensional and geometrical accuracy between different polymer AM processes [ 6 ]. Other studies [ 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 ] analyzed the influence of design, process, and production factors on part quality.…”
