Abstract: A hole former for use in casting a gasket within an opening of a structure of the type used in underground water systems, such as a manhole. The hole former includes a body defining a central axis and an outer peripheral surface, with at least one gasket retention element projecting radially outwardly from the outer peripheral surface to interface with a corresponding locating feature of the gasket. In this manner, axial shifting or movement of the gasket with respect to the hole former is restricted, thereby positively locating and retaining the gasket on the hole former before and during the casting process. The hole former may have a compound curvature, with the gasket retained around the periphery of the hole former in a compound curved configuration.

Abstract: A method 100 for generating and dispensing a powdered 60 release agent during an additive manufacturing build is disclosed. A solid body 28 of release agent material is ground insitu by a grinder 50 and dispensed on a surface of the part 72 to prevent adhesion of an adjacent layer of a base material 70. With the addition of the powdered 60 release agent, a support structure 76 is easily separated from the base material 70 when the part 72 is complete, saving time and preventing the part 72 from sustaining unintentional damage. Since no powdered 60 release agent is actually loaded or stored in the apparatus 20, the potential for spillage, waste, inconsistent dispensing, inadvertent dispensing, and clumping due to humidity is eliminated.
