Latest Patents

One of Bullen's latest patents is titled "Forming structures from CAD solid models." This invention discloses a method and apparatus for embedding features and controlling material composition in a three-dimensional structure. The invention enables the control of material characteristics within a structure made from a plurality of materials, directly from computer renderings of solid models of the components. The method utilizes stereolithography and solid model computer file formats to control a multi-axis head in a directed material deposition process. Material feedstock is deposited onto a pre-heated substrate, creating a three-dimensional article with complex geometric details through layer-by-layer deposition. The invention also addresses thermal management of finished solid articles, which is not available through conventional processing techniques. This is achieved by incorporating embedded voids and/or composite materials, including dissimilar metals. The finished articles are designed to control pressure drop and produce uniform coolant flow and pressure characteristics. High-efficiency heat transfer is engineered within a solid structure by integrating other solid materials with diverse indexes. Additionally, the invention allows for embedding multi-material structures within a normally solid component, resulting in articles with diverse mechanical properties. Laser and powder delivery systems are integrated into a multi-axis deposition head with a focused particle beam to minimize material waste.
