摘要： Methods and apparatus for preparing a layer of an object being fabricated by a three-dimensional printing process. Embodiments of the invention combine selective deposition with selective curing to benefit from the respective advantages of both techniques. Multiple printing heads deposit a two-dimensional cross section of the object being fabricated on a substrate which is transparent to curing radiation. The multiple printing heads selectively deposit different object body materials in different regions of the cross section and also selectively deposit regions of support material as necessary. The transparent substrate is then moved into registration with the object being fabricated so that the new layer is in contact with the object body, and an ultraviolet two-dimensional image of the cross section is projected through the substrate to selectively cure the new layer.

摘要翻译：描述了一种用于制备三维物体的方法。该方法可以包括通过基于层的横截面的图像数据选择性地将液体材料沉积在透明基板上来形成层，所述图像数据至少包括体区，其中材料在透明托盘上延伸在定义身体区域的轮廓之外; 使该层与先前凝固的层连接在升高的制造平台上; 并且通过根据横截面的高分辨率图像数据通过透明基板照射具有固化辐射的层来选择性地固化液体材料，使得在轮廓外延伸的材料保持未固化。
