Abstract: A system for rapidly producing a plastic part from a curable liquid which solidifies when subjected to ultra-violet light energy operates with a processor and computer aided design software. The system includes a receptacle and a moving mechanism which is electrically coupled to the processor. The receptacle stores the curable liquid part of which lies in a solidification plane. The system also includes an electronically erasable mask, a drawing device and a projecting system all of which are electrically coupled to the processor. The electronically erasable mask is an ultra-violet wavelength isolating image buffer. The drawing device may be a back lighted liquid crystal display or a high resolution cathode ray tube or an infrared diode laser raster scanner and electronically draws a plurality of images of successive cross-sectional laminae onto the electronically erasable mask.

Abstract: An improved stereolithographic system which produces a three-dimensional object from a heat curable fluid medium which is capable of solidification when subjected to heat includes a computer-aided design controller, a container, an elevator platform and a first servo mechanism which incrementally drives the elevator platform in response to the output signals. The improved stereolithographic system also includes an elongated carrier which is movably coupled to the container, a second servo mechanism which incrementally drives the elongated carrier along the two side walls of the container in response to the output signals, a plurality of spot-sources of heat and a switching network. Each spot-source of heat may be individually switched on and is serially disposed on and fixedly coupled to the bottom surface of the elongated carrier on the bottom surface adjacent to the designated working surface. The switching network individually switches on each spot-source of heat in response to each set of output signals.

Abstract: An inspection/detection system is for use in forensic applications. The inspection/detection system includes a carrying case which has a cover-lid, a light module and a power supply module. The carrying case is a rectangular box with a closed end and an open end to which the cover-lid is hingedly coupled. The light module is mounted within the carrying case and has an output aperture. The light module may be an argon laser head. The power supply module is disposed within the carrying case and energizes the light module to generate light energy therefrom. The inspection/detection system also includes an optical connector and a shutter assembly. The optical connector is optically coupled to the output aperture. The shutter assembly is optically coupled to the optical connector. The inspection/detection system further includes a flexible optical fiber, a remote control handpiece and a heat exchanger. The flexible optical fiber cable is optically coupled to the optical connector.
