Abstract
A layerwise production method of a tangible object (). A layer of uncured building material is provided onto a carrier (). Repeatedly, method cycles are performed, each comprising: providing layer data corresponding to an object layer, selectively exposing the layer of building material based on the layer data for curing thereof, and providing a next layer of building material onto the preceding layer. Each method cycle further includes verifying the cured preceding layer for identifying regions of insufficiently cured building material, and adapting a radiation dose locally for the next layer dependent on whether or not a location to be exposed in accordance with the layer data of the next layer coincides with one of the identified regions of insufficiently cured building material in the preceding layer.
