Abstract: An extrusion-based AM 3D printing system including a printhead assembly having a feedstock liquefying unit and a heating element that is configured to generate heat for transforming solid feedstock material into liquefied feedstock material that is extruded as an extrudate via a nozzle of an outlet portion of the feedstock liquefying unit. The system further includes an extrudate temperature sensor for determining a temperature of the extrudate freshly exiting the nozzle while the printhead assembly is positioned at a non-printing location, and a control unit that is configured to execute a heater controlling algorithm that is configured to generate initial control settings for the heating element, and to execute the heater controlling algorithm for generating adjusted control settings for improving control of the temperature of the extrudate. A method of improved control of the extrudate temperature.

Abstract: A cleaving mechanism and related method is adapted to cleave an optical fiber and thereby produce a cleaved end on the optical fiber. The cleaving mechanism includes a fixture, a cleave tool for cleaving the optical fiber, a clamp, a scoring member, and a tensioner. The fixture and clamp may hold the optical fiber without substantial twisting of the optical fiber. The fixture and/or the clamp may include a set of flexures that may include a pair of bending beam elements. The tensioner may include a voice coil and may detect slippage of the optical fiber. The tensioner may tune tension on the optical fiber and thereby tune a cleaving angle of the cleaved end. The cleaving mechanism may further include a vision system and thereby further tune the tension. The tensioner may compensate for wear of the cleaving mechanism. The cleave tool may include a bending anvil. The optical fiber may be included in a fiber optic cable that may further include a protective layer surrounding the optical fiber.

Abstract: The present invention is related to a method for fabricating an electromagnetic actuator.
