    Abstract: A method for repairing a multi-layered damage area in a multi-layered composite structure. The method first includes obtaining depth measurement data, and obtaining topographical measurement data by laser scanning the surface of the damage area. This depth measurement data and topographical measurement data are inputted into a microprocessor along with thickness data of each layer. All inputted information is correlated among itself to thereby internally produce a three-dimensional damage area display-replica and interpolate a two-dimensional pattern of each layer of the damage area and of the surface of the damage area. The damage area is removed by first projecting a two-dimensional laser pattern of the damage area thereat on the surface of the structure, and thereafter manually removing the area to produce a void. Repair is accomplished by projecting onto respective replacement material a two-dimensional laser image pattern of each layer and manually cutting that layer according to the appropriate pattern.

    Abstract: A number of non specific, preexisting images are combined using an optical process of masking that (for purposes of clarity the following assumes 3 images are used) removes 2/3 of the first image in a sequential/lenticular pattern, replacing the removed image segments with 1/3 of each of the other two images also sequentially. These combined images are then separated by thin black separation lines using a special burning mask. This series of images and black lines is then visually decombined through the use of a clear thickness of material sandwiched together with the combined transparency and, using a non opaque adhesive, to a decombining mask in registration. This product is then able to be trimmed down and inserted into any preexisting light box. The product when back lit and viewed from the front creates the illusion of 3 complete, separate and sequential, non ghosting images that appear separately depending upon the viewers angle in relationship to the horizontal plane of the standing image.

The beads are deposited along vectors, during X/Y relative movement, on the stage, one at a time, layer-upon-layer, to build the model. The jets and platform are moved relatively to one another in accordance with instructions from the computer (controller) to form each layer in the X-Y plane (in a manner analogous to an X-Y vector plotter) and either the stage or the jets may move in the Z direction to allow the jets to form subsequent layers.

  • Patent number: 5496683
    Abstract: A photo-setting resin is shaped into a three-dimensional resin model by scanning successive resin solution layers of a photo-setting resin solution with a radiation beam to form a stack of scanned set layers of photo-setting resin, each of the successive resin solution layers having a shaped region of an isometric section. The radiation beam is scanned along a contour line of the shaped region to set the shaped region along the contour line, and scanned in a raster scanning mode to set the shaped region inwardly of the contour line. Specifically, the radiation beam is scanned along a first line which is spaced a first distance inwardly from the contour line thereby to set the shaped region along the first line, and the radiation beam is scanned inwardly of a second line which is spaced a second distance inwardly from the contour line thereby to set the shaped region inwardly of the second line. The first distance is smaller than the second distance.

  • Patent number: 5432045
    Abstract: A photo-solidification modeling apparatus and a photo-solidification modeling method, wherein the reliability of an operation for coating the upper surface of a solidified layer with an unsolidified liquid is improved and the time required to carry out the same operation is reduced. To meet the purpose, a clearance is formed between the lower surface of a recoater travelling on a solidified layer and the upper surface of the solidified layer. When this condition is satisfied, an unsolidified liquid is introduced onto the solidified layer by virtue of both the force of the lower surface of the recoater which drags the unsolidified liquid and the nature of the unsolidified liquid entering the clearance. When recesses are provided in the lower surface of the recoater, the liquid adsorbed to the surfaces of the recesses is also introduced onto the unsolidified layer.

  • Patent number: 5284536
    Abstract: A method of fabricating model trees and plants for decorating a diorama. The model is made from stacking foliage disks on a telescoping dowel, which functions as an imitation trunk. First, an outline of leaves and branches is drawn within a panel on paper. Next, the outline is shaded in to obtain a silhouette thereof. Numerous foliage disks can be clustered on a single panel to conserve space and to facilitate mass production. The silhouette is photographed to obtain a reverse image. Then through photolithography and etching, a metal template of the reverse image is made. The template is overlaid on a wood veneer having a kraft paper backing, and is laser cut. After laser cutting, each foliage disk can be separated from the veneer sheet. An assembly hole is provided in each foliage disk to facilitate attachment to the dowel. In an alternative embodiment, the trunk can be fashioned from braided wire with one end that is unraveled and flared outwards.

  • Patent number: 5203944
    Abstract: A method for forming a three-dimensional article by thermal spraying utilizes a plurality of masks having a support layer with a removable liner thereon and a cut-away portion. The masks correspond to cross-sections normal to a centerline through the object. A set of masks defines all cross-sections through the object. A first mask is placed above a work surface and sprayed with a deposition material forming a first layer portion of the deposition material within the cut-out and second layer portion on the liner. The liner and second layer portion of deposition material thereon are removed. A second mask is placed over the remaining support portion of the first mask and sprayed with deposition material therein. Then the liner portion of the second mask and deposition material therein are removed. This process is repeated until the three dimensional article is formed. Then the mask support portions surrounding the article are removed from the article.

  • Patent number: 5015312
    Abstract: A method and apparatus are disclosed for constructing a three-dimensional surface of predetermined shape and color from a length of sheet material. A series of color profiles are made along one side of the sheet material in sequence, each color profile corresponding in shape and color to the shape and color of a different cross-section of the surface to be constructed. A coating of a pressure sensitive adhesive is then applied to one side of the sheet material. Areas on the sheet material outside of the profiles are then removed and discarded so as to leave a series of unconnected planar elements, each planar element having an edge shape or outline corresponding to a cross-section of the surface with the color profile itself forming at least a color border or margin on the surface of its respective planar element around the edge. The planar elements are then stacked one on top of the other in proper alignment and sequence and individually laminated together to produce the desired three-dimensional surface.
