The intermediate machining path surfaces extend to a shape that simulates a cutting beam (e.g., a waterjet, a laser beam, etc.) of the tool. For a flat workpiece, the machining path surfaces may extend from a top surface of the workpiece, which is a tool beam entrance surface, to a bottom surface of the workpiece, which is a tool beam exit surface. An operator is able to visualize the cuts to be made and the actual finished object geometry, without requiring the creation of multiple CAD solid models.

Sheet lamination modeling method and sheet lamination modeling apparatus

The invention relates to a sheet lamination modeling method and a sheet lamination modeling apparatus for forming a three-dimensional object by stacking and gluing sheets together. In the invention, an upper sheet (2Y) is stacked on top of a lower sheet (2X) which is cut into an effective area (V1) constituting the three-dimensional object and a waste area (U1) not constituting the three-dimensional object, an adhesive (4) is supplied between the lower sheet (2X) and the upper sheet (2Y) and onto an area which extends outwardly of an overlapping area covering both of an effective area (V2) of the upper sheet (2Y) and the effective area (V1) of the lower sheet (2X) to thereby glue the lower sheet (2X) and the upper sheet (2Y) together, and the upper sheet (2Y) is cut into the effective area (V2) and a waste area (U2). As a result, according to the invention, it is possible to easily obtain a strong three-dimensional object without separation or deformation.

Selective laser sintering with assisted powder handling

A method and apparatus for selectively sintering a layer of powder to produce a part comprising a plurality of sintered layers. The apparatus includes a computer controlling a laser to direct the laser energy onto the powder to produce a sintered mass. The computer either determines or is programmed with the boundaries of the desired cross-sectional regions of the part. For each cross-section, the aim of the laser beam is scanned over a layer of powder and the beam is switched on to sinter only the powder within the boundaries of the cross-section. Powder is applied and successive layers sintered until a completed part is formed. Preferably, the powder is deposited to the target area of the laser and attains high bulk density during sintering.

Method of making a three-dimensional object by stereolithography

An improved method for stereolithographically making an object by alternating the order in which similar sets of vectors are exposed over two or more layers. In another method, a pattern of tightly packed hexagonal tiles are drawn. Each tile is isolated from its neighboring tiles by specifying breaks of unexposed material between the tiles. Using an interrupted scan method, vectors are drawn with periodic breaks along their lengths. In another method, modulator and scanning techniques are used to reduce exposure problems associated with the acceleration and deceleration of the scanning system when jumping between vectors or changing scanning directions.
