    摘要： A method for forming a duct interconnect generally includes providing a digital model of a first duct structure and a second duct structure, the first duct structure including a first duct section having a passage for conveying a substance and an interconnect component moveably and captively coupled to the duct section. The second duct structure includes a second duct structure and a second interconnect component. The process includes forming, via a direct manufacturing procedure (e.g., stereolithography), a physical model of the first duct and second structures in accordance with the digital models, wherein the interconnect component has a locked and unlocked state, and wherein the unlocked state corresponds to a predetermined compressive force between the first duct structure and a second duct structure.

    摘要： In addition to working curves, other equally important, but previously not understood, relationships exist for both the green strength and the cured line width of ceramic-loaded resins. These characteristics of cured parts are strongly affected by the dose rate, a parameter usually controlled with laser power. Multiple smaller doses are used to produce a total integrated dose. Multiple exposures benefit from using high power to produce a fast process. However, since the dose for a given layer is broken into several smaller doses, the negative effect of high power on strength and cured linewidth is reduced.

    摘要翻译： 除了工作曲线之外，其他同样重要但以前还不了解的是，陶瓷负载树脂的生坯强度和固化线宽度存在关系。 固化部件的这些特性受到剂量率的强烈影响，通常用激光功率来控制。 使用多个较小的剂量来产生总的一体化剂量。 多次曝光受益于使用高功率产生快速过程。 然而，由于给定层的剂量被分解成几个较小的剂量，因此降低了高功率对强度和固化线宽的负面影响。

    摘要： A method and apparatus for creating pre-stressed zones in concrete. In one embodiment, a circular blade is coated with a chemical which retards the setting of the concrete. The circular blade is then rolled through the wet concrete, thus transferring the retarding chemical from the blade into the concrete. The region of wet concrete that has the retarding chemical introduced into it does not set until after the surrounding concrete has set and shrunk, thus creating a pre-stressed zone which typically manifests itself as a crack, visible upon setting of the wet concrete. Other embodiments describe alternative ways of introducing the chemical into the wet concrete.

    摘要： A gelcasting method of making an internally graded article alternatively includes the steps of: preparing a slurry including a least two different phases suspended in a gelcasting solution, the phases characterized by having different settling characteristics; casting the slurry into a mold having a selected shape; allowing the slurry to stand for a sufficient period of time to permit desired gravitational fractionation in order to achieve a vertical compositional gradient in the molded slurry; gelling the slurry to form a solid gel while preserving the vertical compositional gradient in the molded slurry; drying the gel to form a dried green body; and sintering the dry green body to form a solid object, at least one property thereof varying along the vertical direction because of the compositional gradient in the molded slurry.
