Resin 3D printing can be an intricate process, and several factors can contribute to the failure of a print. Here are some possible causes why models are failing during resin 3D printing: Insufficient support structures: 3D resin printers require support structures to hold the model in place while it's being printed. If these structures are insufficient, the model may not be supported correctly, leading to warping, distortion, or complete failure. Poor calibration: The printer must be calibrated correctly to ensure that the print bed is level, and the printer's settings are correct. If the printer is not calibrated correctly, it can result in an uneven print surface or improper layer adhesion, leading to printing failure. Inaccurate exposure settings: Resin printers use UV light to cure the resin. The exposure time and intensity must be accurate, or the resin may not cure correctly, leading to print failure. Contaminated resin: Resin can become contaminated with dust, debris, or other substances that can interfere with the printing process. This can cause problems with the curing process, leading to failure. Model design: The design of the model itself can also affect the printing process. Make sure that the model is suitable for 3D printing and that it has been prepared correctly for resin printing. If the model has overhangs or other complex features, it may require additional support structures to print correctly.
