摘要： There is provided methods and apparatus for compensation of intensity profiles of imagers used in three-dimensional modelers. The intensity profile (30) of the actinic radiation projected from the imager (20) is determined by a variety of techniques, including but not limited to manually operated sensors (62), exposed and scanned actinic radiation sensitive paper, and intensity prof ilers (102). Once the intensity profile of the imager is determined, each layer of the solidifiable liquid material is cured by projecting a plurality of patterns (46) (as opposed to a single pattern) defining the two dimensional cross -section ot the part being cured. The patterns vary in duration, number, and / or shape to correlate to the intensity profile so that a single layer of selectively cured solidifiable liquid materia] is cured with a substantially equivalent (or otherwise controlled) amount of actinic radiation per unit of surface area to provide generally controlled and consistent part quality.

摘要： Methods for generating supports (30) for parts (50) produced by solid freeform fabrication ("SFF") are disclosed. The method includes defining a plurality of layers (L) that make up the part, and for each layer, determining those regions (R) that require support. The method also includes merging the regions for the different layers (L) into one or more common regions that require support, and providing at least one support for each of the one or more common regions. The result is that fewer supports are used as compared to conventional SFF fabrication methods.

摘要： Solid imaging apparatus and methods for use are disclosed that reduce the amount of uncured solid imaging build material remaining on a completed build object following the completion of the solid imaging build process. The amount of uncured build material is reduced through the use of either an uncoating web that removes excess build material from the build object during the course of the building process or an ink jet source of build material that uses only as much build material as is necessary for the fabrication of the build part. Also disclosed is an imager assembly for use with such a solid imaging apparatus that incorporates two or more individual imagers in an array and accounts for variations in the intensity and alignment of adjacent imagers. The apparatus can be modified for semi-continuous operation and for integrating into a manufacturing operation, if desired.

摘要： A solid imaging apparatus is provided that includes a replaceable cartridge containing a source of build material and an extendable and retractable flexible transport film for transporting the build material layer-by-layer from the cartridge to the surface of a build in an image plane. An operator using the device needs merely to remove a spent cartridge and replace it with a fresh cartridge to continue solid imaging virtually uninterrupted. The apparatus also includes the capability of withdrawing and inserting an imager without the operator having to perform a separate alignment step. A brush attached to the transport film and forming part of the cartridge provides for intra-layer removal of excess uncured build material. If desired, the apparatus can produce a fully reacted build. A high intensity UV source cures the build between layers. An injection molded build pad is designed to hold a build in an inverted position for improving the build. The invention also provides for tilting the build elevator to reduce air entrainment and for releasing the build from the image plane.
摘要翻译：提供了一种固体成像设备，其包括含有构建材料源的可更换盒以及用于将构建材料逐层从盒施加到图像平面中的构建表面的可伸展和可缩回的柔性传输膜。使用该设备的操作员仅需要移除已用过的墨盒并将其替换为新墨盒以实际上不间断地继续固体成像。该设备还包括撤回和插入成像器的能力，而操作者不必执行单独的对准步骤。连接在输送薄膜上并形成筒的一部分的刷子提供层内去除多余未固化的建造材料。如果需要，该装置可以产生完全反应的构造。高强度紫外线源可以固化层间的构造。注塑成型的垫板设计用于将底座保持在倒立位置以改善构造。本发明还提供了使建造电梯倾斜以减少空气夹带并且从图像平面释放建筑物。

摘要： A method and apparatus for making high resolution objects by stereolithography utilizing low resolution materials which are limited by their inability to form unsupported structures of desired thinness and/or their inability to form coatings of desired thinness. Data manipulation techniques, based on layer comparisons, are used to control exposure in order to delay solidification of the material on at least portions of at least some cross-sections until higher layers of material are deposited so as to allow down-facing features of the object to be located at a depth in the building material which is equal to or exceeds a minimum cure depth that can effectively be used for solidifying these features. Similar data manipulations are used to ensure minimum reliable coating thicknesses exist, above previously solidified material, before attempting solidification of a next layer. In addition, horizontal comparison techniques are used to provide enhanced cross-sectional data for use in forming the object. Further, several techniques for automatically performing Z-error correction through the manipulation of a three-dimensional object representation are described. Still further, techniques for producing objects useful for investment casting applications are described, including techniques allowing for the drainage of unsolidified material. A method and apparatus for the automatic generation of vents and drain is also provided.
