    摘要： A stereolithographic device and method including a process module, a control module and a service module. A laser is employed through a dynamic mirror system controlled by the control module to generate solidified cross sections of a selected part design on the surface of a photocurable polymer liquid. By lowering cured cross sections into the vat, additional cross sections can be perpared and joined therewith to define a prototype product. A stationary mirror in the beam path between the dynamic mirror system and the photocurable polymer is employed to make the system more compact and practical. A calibration and normalization process provides correction to distortions and misalignment of the stationary mirror.

    摘要： A stereolithography system employing a more powerful laser and faster dynamic mirrors to speed up part building without sacrificing accuracy is described, especially large or complex parts. A controllable shutter is placed in the beam path of the laser to selectably block the passage of the beam and prevent unwanted solidification. A suitable servo controlled feedback loop is provided to accurately position the mirrors at the higher velocity. Also described is a means to reduce data flow by distributing tasks in a multiple processor environment, and to improve user interaction by the use of a spreadsheet model. These also improve the speed of part building, especially for large or complex parts.

    摘要： Improved apparatus and methods for forming a layer of material over a surface of a previously-formed cross-section of a three-dimensional object in anticipation of forming a next cross-section of the object out of the layer. A volume of material, including at least some excess material, is placed over the surface, and the excess material is swept off by placing the excess material in the predetermined path of a sweeping member, the path being substantially in a plane spaced from a working surface of material. The member may be directed to sweep the excess material away through a successive number of sweeps, which may vary for each cross-section, at least a velocity which may vary for each sweep. Additionally, the clearance between the member and the surface of the previous cross-section may vary for each sweep. A "winged" member is also provided, comprising two legs extending from a base, and a "Trident" embodiment is also provided, comprising three legs extending from a base.

    摘要： Apparatus and methods for stereolithographically forming a three-dimensional object includes a vessel for holding a building material and a smoothing member for forming a uniform coating over a previously formed layer of the object. The smoothing member has a plurality of blades. The smoothing member is swept over a previously formed layer of the object, in at least two directions. Different clearances between the lower surface of the smoothing member and the upper surface of the previously formed layer are used to provide a uniform coating for a subsequent layer over the previously formed layer. The sweeping velocity of the smoothing member can be varied. Retractable needles are attached to the smoothing member for adjusting a blade gap between the lower surface of the smoothing member and the surface of the building material.

    摘要： Certain example embodiments of this invention relate to a method of forming a coating on a glass substrate using combustion deposition. A glass substrate having at least one surface to be coated is provided. A reagent is selected. A precursor to be combusted with the reagent is introduced. Using at least one infrared burner, at least a portion of the reagent and the precursor are combusted to form a combusted material, with the combusted material including non-vaporized material. The glass substrate is provided in an area so that the glass substrate is heated sufficiently to allow the combusted material to form the coating, directly or indirectly, on the glass substrate. The coating may be substantially uniform. In certain example embodiments, a silicon oxide coating may be deposited, which increases visible transmission of the glass substrate by at least about 1.7%.

    摘要： Certain example embodiments relate to the deposition of metal oxide coatings via combustion deposition. In certain example embodiments, the metal oxide coating may be a silicon oxide coating (e.g., SiO2, or other suitable stoichiometry) and, in certain example embodiments, the silicon oxide coating may serve as an anti-reflective (AR) coating. In certain example embodiments, a percent visible transmission gain of at least about 2.0%, and more preferably between about 3.0-3.25%, may be realized through the growth of films on a first surface of the substrate. The coatings produced in accordance with certain example embodiments possess an enhanced transmission increase over previously combustion deposition produced single-layer anti-reflective coatings. This may be accomplished in certain example embodiments by provided mixed or graded microstructure metal oxide coatings (e.g., silicon oxide growths that alternate between using process conditions that produce small nucleation particle size distributions and process conditions that produce large agglomerate nano-particle size distributions) and/or by in situ nano-particle matrix loading of metal oxide coatings via combustion deposition.
