Abstract

The invention utilizes a layered manufacturing process to produce an article (2) having at least one small-width fluid conduction vent (6) produced during the layered manufacturing process. Such small-width fluid conduction vents (6) may have any desirable cross-sectional shape, orientation, and curvature. The invention also includes articles (2) containing at least one small-width fluid conduction vent (6) wherein the article (2) and the small-width vent or vents (6) are simultaneously produced by a layered manufacturing process.

Description

technical field [0001] The present invention relates to layered manufactured articles comprising at least one fluid drainage opening of small width. More specifically, the invention relates to articles in which at least one such drainage port is manufactured during a layered manufacturing process. Still more particularly, the present invention relates to an article in which one or more drainage ports have a varying shape or a non-linear centerline. The invention also relates to methods of making such articles. Background technique [0002] Many manufactured articles include small diameter fluid drainage ports that allow fluid to flow into and / or out of the article or a portion of the article. For example, molds for making articles from expanded polymer beads, such as expanded polystyrene ("EPS"), include a plurality of small width fluid intake ports for introducing vapor into the mold Or lead through the mold so that the polymer beads further expand and bond together. In...
