VERFAHREN UND VORRICHTUNGEN ZUR SCHNELLERKENNUNG UND -KALIBRIERUNG EINES 3D-DRUCKERS, DER EIN VISKOSES MATERIAL VERWENDET

摘要

The invention particularly relates to a method of manufacturing a three-dimensional object by successive deposition of uniform layers of a viscous material, the method comprising a prior calibration operation comprising the following steps: - positioning at least one calibration stop at a distance between a first distance and a second distance from a work surface, the at least one calibration stop being configured to allow the triggering of a signal in the event of contact between the at least one calibration stop and a proximity sensor linked to a scraper; - move (310) the scraper linked to the proximity sensor to one of the at least one calibration stop; - stop movement of the scraper as soon as a signal indicates contact between the calibration stop and the proximity sensor; and- estimating (320) the distance between the scraper and the working surface after stopping the movement, at least one calibration value comprising the estimated distance.
