Abstract: 3D printed articles, especially those composed of elastomeric silicones, are provided with details including corners and surfaces of high accuracy by placing voxels or strands of curable material at target locations, where the actual position of the print head is determined, and this actual location rather than an assumed location is used to control material placement.

Abstract: A measurement system employing a confocal optical systems is used to accurately position a 3-D print head from a printing stage and a part being printed.

Abstract: Improved 3D printed articles are produced in a 3D printing apparatus by controlling the apparatus in response to the measurement of the size, geometry, and/or weight of print materials exiting the discharge device of the apparatus.

Abstract: A fabrication process produces markers for a magnetomechanical electronic article surveillance system. The marker includes a magnetomechanical element comprising one or more resonator strips of magnetostrictive amorphous metal alloy; a housing having a cavity sized and shaped to accommodate the resonator strips for free mechanical vibration therewithin; and a bias magnet to magnetically bias the magnetomechanical element. The process employs adaptive control of the cut length of the resonator strips, correction of the length being based on the deviation of the actual marker resonant frequency from a preselected, target marker frequency. Use of adaptive, feedback control advantageously results in a much tighter distribution of actual resonant frequencies. Also provided is a web-fed press for continuously producing such markers with adaptive control of the resonator strip length.
