A valve-venting method increases the durability of flow restrictors within gas venting valves used on large diameter water and sewer pipelines such that transient high pressure conditions that can cause rapid adiabatic heating of the discharging gases are prevented from causing flow erosion and debris wear induced by the high velocities and thermal softening of the valve components. The method utilizes wear resistant orifice inserts that are more conductive than the valve component to better distribute the heat, and dynamic surge control geometry to slow the heat flow and provide progressive water-hammering control during high pressure events.

Three-dimensional microstereolithographic objects fabricated by microstereolithography are exposed to UV light for one hour to accelerate hardening. The structures are then heated at 175° C. or above for at least 6 hours. The heating temperature may exceed the glass transition temperature, which is the index of thermal softening temperature of materials. The present invention relates to three-dimensional microstructures formed by microstereolithography. Deformation due to a structure's own weight, which generally poses a problem in heat treatment, is reduced with microstructures due to the size effect. As a result, the dimensions of the three-dimensional structure fabricated by the present invention remain almost unchanged before and after the heat treatment.
