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： A laser scanning system in a rapid-protyping system is controlled during vector scanning by providing a commanded-position signal to each of first and second rotary motive devices to rotate respective mirrors of the scanning system, each mirror undergoing acceleration at the beginning of the vector, wherein the commanded-position signals are calculated based on physical mathematical modeling of the acceleration of the mirrors taking into account effects of inertia of the scanning system, and wherein actual positions of the mirrors are measured with fast-response devices and digital feedback control of the mirror positions is employed at a periodic rate sufficiently small to maintain a following error of the laser spot less than about 200 μs at all times. A laser power control method employs a fast-response power meter for measuring laser power.
