Desktop 3D printers often do not include mechanisms for manually fine-tuning printing parameters, which can lead to inconsistencies and errors across prints. To address this, the present study developed a method to track and evaluate printer calibration in office-based settings. A specialized calibration coupon was created with defined tolerances and dimensions to represent ideal geometry and to quantify deviations in the X–Y axes and surface curvature. Two stereolithography (SLA) printers were tested across ten print cycles using two different resin types. Additionally, coupons were positioned at five distinct locations on the build platform to investigate positional effects on accuracy. Analysis revealed no significant differences in X or Y axis measurements across varying positions or resin types (p > 0.05). As desktop 3D printers currently lack a standardized calibration workflow linking design and production, the proposed calibration coupon offers a practical tool for monitoring printer performance and maintaining consistent print quality.
