Abstract: A method and system for calibrating a three dimensional printing system includes a specialized sensor. The three dimensional printing system forms a three dimensional article of manufacture through a layer-by-layer process. Layers are formed by the operation of a light engine selectively curing photocure resin onto a face of the three dimensional article of manufacture. The sensor includes a photodetector overlaid by an optical element. The optical element simulates a “dense portion” of an optical path between the light engine and the face of the three dimensional article of manufacture being formed.

Abstract: A method for moving a mold assembly from a mounted position within a concrete products forming machine includes extending an extraction assembly forwardly from a retracted position at a rear of the concrete products machine to an intermediate position so that terminal ends of the extraction assembly are positioned below a carrying surface of the mold assembly. The extraction assembly is raised at the rear portion of the concrete products machine so that the terminal ends of the extraction assembly contact and raise the carrying surface of the mold assembly up off mold mounting surfaces on the concrete products machine. The extraction assembly is then moved to a fully extended position so that the mold assembly is moved forwardly from the mold mounting surfaces to an operative position whereby the mold assembly can be removed from the extraction assembly and replaced with a replacement mold assembly.

Abstract: This disclosure provides a method of manufacturing a polymer container according to a blow molding or stretch blow molding process, in which the base of the blow mold has at least one orifice for pressurized gas to enter the blow mold through the base. Introducing pressurized gas through the orifice in the blow mold base provides cooling assistance within the gas mold, much earlier than the cooling using conventional methods, which can reduce or eliminate the need for any post mold cooling. This method has been found to be applicable to non-hot fill application bottle and container manufacture.
