Abstract
This study investigates how various additive manufacturing (AM) technologies and parameters influence part quality by fabricating three uniquely designed artefacts. Artefact 1 is a rectangular block with stepped arches, thin and solid extruded features, and holes of varying shapes and sizes. Artefact 2 consists of a base plate with angled overhangs from 15 to 90 degrees. Artefact 3 includes a tall cylinder, a five-step cylinder, and two half arches of different scales. Each artefact was printed ten times using: metal PBF (Inconel 718), nylon PBF (Nylon 12), Vat Polymerization (GRY photopolymer), and material extrusion (nylon carbon fiber). Dimensional analysis was performed using two Mitutoyo CMMs: MiSTAR 555 and CRYSTA Apex V 776. Surface quality was assessed using the Keyence VR-6000 Optical Profilometer. Dimensional deviations from nominal CAD geometry were used to evaluate accuracy and standard deviations, providing insights into how AM technologies impact dimensional consistency, form, and surface quality.
