In this article we will discuss a 3d printer test print (Anycubic RERF) for ideal exposure time on Anycubic resin 3d printer. To avoid under-exposure or over-exposure, it's important to ensure that the resin is exposed at an appropriate time. This case will be bad for printing precise parts and assembly models that demand small tolerances. On the contrary, if it's over-exposed, the object will lose dimensional accuracy and become bigger than its actual size. If the resin print is under-exposed, which means the exposure time is too short, causing some problems like soft and sticky surfaces with imperfect details, poor bed adhesion, delamination and so on. Exposure time varies with different resin 3d printers and resins, so calibration testing for exposure time is a priority before printing. Optimal exposure time is the key to successful resin 3d printing, which refers to the time for the liquefied photosensitive resin to be cured into a solid shape by a UV light source.
