  • Patent number: 7158849
    Abstract: A method for rapid prototyping by using linear light as sources employs DLP (Radiation Hardening Formation) or LCD, together with the portable devices and linear light source to treat the raw material in two stages. The first stage is to spread the raw material to a selected zone by nozzles or rollers and illuminating the material to let the material being processed and have physical o mechanical changes. The second stage is to use more powerful linear light source with the cooperation of the portable DMD (Digital Micromirror Device) or LCD (Liquid Crystal Display) to illuminate the material to make it have a second times of physical o mechanical changes. By the piling up the layers of the material, a complete 3-D work piece is obtained.

  • Publication number: 20060290772
    Abstract: The invention discloses a method of manufacturing rapid prototyping workpiece by projecting a laser beam or other light onto the photo-conductive drum to attach powder materials to form a thin layer, and then coat the thin-layer material on a working platform. A point, line or plane light source of stronger intensity is used to go with the DMD (Digital Micromirror Device) or LCD (Liquid Crystal Display) to produce a physical change or a chemical change in the selected projecting region and combine the materials to become an acceptable property. The method comprises three stages of a process and repeats the process to complete a physical workpiece. The first stage refers to evenly spreading electric charges on a photo-conductive drum, and then projects a laser beam or a visible light onto the photo-conductive drum to electically conduct the electric charges and lower the electric potiential.

  • Publication number: 20050225007
    Abstract: This invention applies a new computer and printer integrated technology to aid forming physical objects rapidly, and the method and apparatus are disclosed to satisfy the market requirements for a quick, reliable, safe, and inexpensive operation. The invention coverts a virtual object stored in the storage device of computer through software that slices the virtual object into many layers. The cross-section of the first layer is sent to a printer or a plotter, and the contour domain is printed or plotted by the printer or plotter. The fluid (not limited to binder) in the printer head is coated onto a layer of uniform distributed porous material which allows the powder and fluid to combine with each other; however, the combining process can be either a natural or an artificial process to enhance the binding force between the fluid and powder. After the first layer is finished, the second layer of powder is uniformly distributed on the first layer, and the contour printing process is repeated.
