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： 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 profilers (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 of 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 material 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.
摘要翻译：公开了通过固体自由形成（“SFF”）产生的用于部件（50）的支撑件（30）的方法。该方法包括限定构成该部分的多个层（L），并且对于每个层确定需要支持的那些区域（R）。该方法还包括将不同层（L）的区域合并成需要支持的一个或多个公共区域，以及为一个或多个公共区域中的每一个提供至少一个支持。结果是与常规的SFF制造方法相比，使用较少的支撑件。

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.
