摘要： A stereolithography system employing a more powerful laser and faster dynamic mirrors to speed up part building without sacrificing accuracy is described, especially large or complex parts. A controllable shutter is placed in the beam path of the laser to selectably block the passage of the beam and prevent unwanted solidification. A suitable servo controlled feedback loop is provided to accurately position the mirrors at the higher velocity.Also described is a means to reduce data flow by distributing tasks in a multiple processor environment, and to improve user interaction by the use of a spreadsheet model. These also improve the speed of part building, especially for large or complex parts.

摘要： For increasing the safety monitoring of a plant with several functional units, such as a production plant, the invention provides a method and apparatus, in which each functional unit is individually monitored or checked by its own redundant two-channel safety device. The safety devices constantly inform one another of their monitoring state. In the case of a malfunction of at least one functional unit or safety device, at least one safety-relevant actuator is operated. For achieving this objective, an apparatus is constructed with each functional unit being associated with a safety device and the safety devices are interconnected so that, in the case of a malfunction of at least one functional unit or safety device, at least one safety-relevant actuator is operated.
