Abstract
According to some aspects, techniques are provided to more accurately produce fine features in additive fabrication. According to some embodiments, the techniques comprise a process that amplifies exposure to edges and thin positive features whilst not substantially affecting negative features. In particular, an area to be cured may be adapted using signal processing techniques to produce an energy density map. The area may subsequently be cured according to the generated energy density map by, for example, adjusting the scan speed, light power and/or number of passes of the light beam according to the map. As a result, the net exposure to edges and thin positive features may be amplified.
