Curing is the process of solidifying liquid resin using UV light. Sunlight contains UV light and it can cause the liquid resin to solidify/cure. The recommended curing time per single layer is usually between 5-12 seconds depending on the resin used - there may be exceptions. Layer height, object size, and exposure (curing) time are the three factors that have a major impact on the length of the printing process and the quality of the printed object.
