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： A continuous-wave (CW) ultraviolet (UV) curing system for solid freeform fabrication (SFF) is provided, wherein the curing system is configured to provide an exposure of UV radiation for one or more layers of UV-curable material. One or more UV exposures may initiate curing of a curable material in the layer dispensed by a solid freeform fabrication apparatus. One approach to provide the single or multiple UV exposures is the use of one or more UV LEDs, which generate UV radiation without generating any substantial amounts of infrared (IR) radiation at the same time. This allows for the curing process to be energy efficient and also allows for the SFF system to be far less complex.
摘要翻译：提供了一种用于固体自由形成（SFF）的连续波（CW）紫外线（UV）固化系统，其中固化系统被配置为提供一个或多个UV可固化材料层的紫外线辐射。一个或多个UV曝光可以引发在固体自由形成制造装置分配的层中固化可固化材料。提供单次或多次UV曝光的一种方法是使用一个或多个UV LED，其同时产生UV辐射而不产生任何大量的红外（IR）辐射。这使得固化过程能够节能并且还允许SFF系统复杂得多。

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 selective deposition modeling method and apparatus for dispensing a curable phase change material. The dispensing temperature of the material is set at or less than a thermally stable temperature value for the material in which the reactive component of the material remains substantially uncured when held at the temperature for a desired time period. The dispensed material is provided with an environment that enables the material to solidify to form layers of the object. The solidified material is normalized to a desired layer thickness and is then cured by exposure to actinic radiation. In a preferred embodiment a UV curable phase change material is dispensed at about 80 °C and has a viscosity of about 13 to about 14 centipoise at this temperature. The cured material provides substantially increased physical properties over thermoplastic phase change materials previously used in selective deposition modeling.

摘要： A material feed system for solid freeform fabrication. The build material is delivered in discrete or quantized amounts by the feed system in a non-flowable state to the dispensing device and the material is then changed to a flowable state prior to being dispensed. The feed system can be used to build three-dimensional objects in color, if desired. In one embodiment individual cartridges with build material are loaded into a magazine on the feed system which is integrated with a waste removal system. As the build material is expelled from the cartridges, waste material is deposited into the cartridge. Once all the build material has been expelled, the waste material is hermetically sealed in the spent cartridge which is then ejected from the system. The hermetically sealed cartridges protect operators from contact with the reactive waste material making the system safe for the office environment.

摘要： An improved layer normalizing device (10) for use in dimensionally normalizing layers of a three-dimensional model produced by a selective deposition modeling technique. The layer normalizing device employs a wicking member (12) having a body (14) and a normalizing surface (16) for dimensionally normalizing the object while the object is being built layer by layer. The body includes a plurality of interstices (18), and when the wicking member is sufficient heated to cause the build material to become flowable, excess material is drawn by capillary action from the layer of the object being normalized and into the wicking member. A refreshing means is provided to remove the excess build material from the interstices of the wicking member and allow the wicking member to draw additional build material by capillary action.
