Device for automatic powder extraction/removal in printer has controller that compares measured deposit/concentration value with thresholds, removes powder deposits/reduces concentration via suction, powder agitation and/or blowing devices

摘要

The device has at least one measurement device for detecting powder deposits, at least one measurement device for detecting powder concentrations in the ambient air and a controller (5) that compares a measured value with defined thresholds and removes the powder deposits and reduces the powder concentration via suction (7), powder agitation (6) and/or blowing devices.
