The present disclosure generally relates to additive manufacturing of an object using both a digital light processing (DLP) projector and a focused energy source to irradiate a photopolymerizable material, and apparatuses and methods for the same. The DLP projector irradiates and cures an outer perimeter of the object, and the focused energy source irradiates and cures an inner region of the object. In a preferred embodiment, irradiation by both the DLP projector and the focused energy source occur from underneath a tank holding the photopolymerizable material and through a transparent window.

The present disclosure generally relates to methods for additive manufacturing (AM) that utilize a computer aided design (CAD) model of a part to develop a layer representation of the part. The method includes: determining a build layer thickness of an additive manufacturing apparatus; identifying a feature of the part within the model; determining that the feature is not aligned along the z-axis based on the build layer thickness; and moving the feature within the model along the z-axis by a feature offset such that the feature is aligned along the z-axis.
