20130119577 | METHOD FOR REDUCING STRESS IN THREE DIMENSIONAL MODEL - An apparatus and method of fabricating a three-dimensional model which reduces occurrence of one a hairline crack(s), stress fracture(s), break(s), flaw(s) and/or other imperfection(s) in the final three-dimensional model. The method comprising the steps of selecting the model material, selecting the sacrificial material, and adding at least one additive to the sacrificial material for at least one of increasing the thermal conductivity, decreasing a coefficient of thermal expansion or decreasing an ability of the sacrificial material to transmit stress to the model material. The three-dimensional composite model is built by depositing a plurality of layers one on top of another. Following completion of the three-dimensional composite model, using at least one of the increase in the thermal conductivity, the decrease in the coefficient of thermal expansion and the decrease in the ability of the composite sacrificial material to transmit stress to the model material for removing the composite sacrificial material from the model material without creating any hairline crack(s), stress fracture(s), break(s), flaw(s) and/or other imperfection(s) in the final three-dimensional model. | 05-16-2013 |
20130011562 | METHOD FOR FABRICATING THREE DIMENSIONAL MODELS - A method of fabricating a three dimensional model from a composite model formed by a plurality of layers. The composite model comprises at least one shell material encasing and enclosing a build material. The method comprises the steps of (1) depositing a build layer of the build material onto a preceding layer, (2) removing a selected area of the build material from the deposited build layer; (3) depositing the shell material in any removed selected area of the build material; and (4) reducing the build layer to a desired final thickness for supporting a next build layer. Then repeatedly repeating steps (1) through (4) for each build layer until the composite model is completed. Finally, the undesired extraneous material, and possibly the shell, are removed to obtain the final model. | 01-10-2013 |
20110285052 | METHOD AND APPARATUS FOR FABRICATING THREE DIMENSIONAL MODELS - An apparatus and method for fabricating a three dimensional model from a composite model formed or a plurality of successive layers of model material and sacrificial mold material. Each successive layer is constructed by depositing, drop-by-drop, at least one line of sacrifical mold material delineating at least one boundary of the model material within the layer and thereafter depositing the model material onto all delineated regions of the layer by spray deposition. Each successive layer is completed by a planing process which removes the undesired thickness of both the sacrificial and the model materials. Following completion of the composite model, the sacrificial mold material is removable from the composite model, by a process effecting only the sacrificial mold material, to produce the three dimensional model. A device, for depositing the model material at the rate faster than the rate that the mold material is deposited, is also described. | 11-24-2011 |
20100021638 | METHOD FOR FABRICATING THREE DIMENSIONAL MODELS - A method for fabricating a three dimensional model by fabricating a composite model formed of a plurality of successive layers comprised of one or more materials wherein each successive layer is formed by depositing at least first material delineating boundaries of at least one first area of the layer by a drop-by-drop deposition and depositing at least a second material over the layer by a rapid deposition method, and may include the deposition of a third material by a drop-by-drop or rapid deposition method and will include planing the layer to a uniform thickness and selectively removing the first and second materials, and third material if present, by successive removal methods, each of which effects only one of the materials. | 01-28-2010 |
