out with the aim of investigating the feasibility of localizing this technology, reducing manufacturing costs, an‎d improving its accessibility. All major components of the printer, including the frame, Z-axis, resin tank, optical system, power supply, an‎d external enclosure, were designed, machined, an‎d assembled domestically. For the frame, laser-cut steel sheets with powder coating were used to enhance structural rigidity an‎d mechanical stability. Moreover, a high-transmittance protective glass layer was added above the display to prevent resin leakage an‎d extend the lifespan of the optical components. To eva‎luate the printer’s performance, a series of stan‎dard calibration tests were conducted. The results demonstrated that the printer, with an optimized exposure range of 1.4 to 1.5 seconds, was capable of producing parts with high dimensional accuracy an‎d fine surface details. Dimensional verification using a calibration cube confirmed that the printing accuracy in all axes was within 50 micrometers. From an economic stan‎dpoint, the total manufacturing cost of the developed printer was estimated at approximately 28 million IRR, which represents a 26–30% reduction compared to commercial 2K resin printers with similar specifications. These findings indicate that domestic development of resin 3D printers is both technically an‎d economically feasible, an‎d can serve as a significant step toward localization an‎d industrial expansion of additive manufacturing technologies in Iran.
