  • Patent number: 6907307
    Abstract: In solid freeform fabrication processes that make use of a removable support material, pre-calculation of the amount of support material needed for a build is difficult (inaccurate or slow) because the digital data for generating the support material is often not generated until the build is in progress. A method is proposed that has been shown to generate rapid and accurate estimates of the amount of both build and support material needed before a build begins, to accurately predict before a build begins when replenishment materials are needed, and to track material consumptions over time.

  • Patent number: 6631307
    Abstract: A method is described which allows certain Optical Proximity Corrections to be computed in a few minutes. This has been achieved by limiting changes to the optical mask to the addition of two sets of serifs (one larger than the other) at the appropriate vertices in the layout mask. A key feature of the method is that identification of which serifs will be within a critical distance from a neighbouring edge (and have therefore to be smaller) is performed by the application of a few simple logical operations. This results in a corrected mask that can be generated in a few minutes, as opposed to many hours.

    Abstract: In order to produce a reproduction of an object such as a human face, a three-dimensional form of the object is measured with a three-dimensional measuring device, and the measured form is displayed. After a user approves the displayed form, a material is worked according to the measured form to work a reproduction of the object. If the user cancels the displayed form, the form is measured again and the measured form is displayed. Characteristics of the measured form are extracted, and an appropriate material is selected among a plurality of materials. On the other hand, the data of the measured form are converted to work data with reference to the size and the quality of a product to be worked which have been stored in a database. Preferably, the data are compressed in the depth direction in order to shorten the working time. Then, the material is worked in a series of processes from the form input to the working in a simple way, and the user can obtained a desired three-dimensional reproduction.

  • Patent number: 6405095
    Abstract: A solid freeform fabrication process and apparatus for making a three-dimensional object. The process comprises the steps of (1) operating a material deposition sub-system for dispensing droplets of solidifiable liquid compositions on demand onto selected spots of an object work surface, for using a focused heat source to maintain a heat-affected zone on the work surface, and for creating a weld pool of molten materials on this work surface by injecting selected powder particles into this heat-affected zone and (2) during the material deposition process, moving the deposition sub-system and the work surface relative to each other in an X-Y plane defined by first and second directions and in a Z direction orthogonal to the X-Y plane so that the materials are deposited to form a first layer of the object. The material in the weld pool solidifies after the heat-affected zone moves away to build portions of a layer. These steps are repeated to deposit multiple layers for forming a three-dimensional shape.

    Abstract: Elongation in the circumferential direction of a rotary formed body is produced only within a model zone, and the approximate toric plate shape is maintained as the overall shape of the body, and the rotation axis of the body is positioned on a straight line connecting axes of rotation of a main roll and a mandrel roll. Moreover, the velocity of each nodal point and on imaginary cutting planes, that is a velocity boundary condition is expressed by a linear combination of coefficients comprising a radius of the imaginary cutting planes, and angles made by the imaginary cutting planes, with respect to three variables comprising an increasing rate of the radius of the body, an angular velocity for rotation about the rotation axis of the body, and a correction value for the traverse velocity of the rotation axis of the body.

  • Publication number: 20020013636
    Abstract: A dental prosthesis is made by first forming a model of a patient's dentition. A three dimensional digital data corresponding to the surfaces of the model is then created. Based on this data, a three dimensional digital data file is then created substantially corresponding to the dental prosthesis to be manufactured. The three dimensional digital data of the dental prosthesis to be manufactured is next transmitted to automated prototyping equipment, and using the automated prototyping equipment, a wax pattern of the dental prosthesis is manufactured based upon this three dimensional digital data of the dental prosthesis. Finally, using this wax pattern in the lost wax investment casting process, the dental prosthesis is made. Prior to investment casting, marginal edges of the wax pattern are adjusted manually.
