Abstract
Devices, systems, methods and computer program products are disclosed that facilitate part layer curing by an additive manufacturing device wherein each element of the part layer is exposed to light from a light source until the element receives sufficient energy to cure. In an aspect, received energy is calculated based on both the light received directly from the light source and light received from surrounding elements due to dispersion and other effects. The present disclosure enables consistent curing across a part layer, facilitate the creation of sharp outer structures, and allow fragile structures to be built alongside larger structures without a loss of quality, clarity, or resolution.
