This study presents a concept to address the dimensional and geometric viability of three-dimensional (3D) printers with test artifacts. These test artifacts we named as Geometric Element Test Targets (GETT™). GETT™ offers a simple method for quantitative appraisals of the dimensional performance of additive manufacturing processes. The design of GETT™ relies on logistically positioned and decreased feature dimensions. One characteristic of GETT™ is that the dimensional failures introduced may be inspected visually and quantitatively assessed through graphical analyses. We will illustrate the use of GETT™ to determine a printer's resolution through samples produced from fused deposition modeling (FDM) printers. Although the demonstration is from FDM systems, the concept is expected to hold for all 3D printing processes and can be process-specific. The potential applications of GETT™ include standardization, reference targets, in-line system control, and more.
