Abstract
Disclosed is a filter system for an additive manufacturing device for purifying a process gas of the additive manufacturing device wherein, in order to purify a volume of process gas during operation, the filter system has at least one permanent filter. The permanent filter is configured so as to be thermally stable in a manner such that during operation, the permanent filter is stable at a temperature of more than 110° C. Further disclosed is an additive manufacturing device as well as an additive manufacturing process.
Claims10
An additive manufacturing device for manufacturing a component in an additive manufacturing process, the additive manufacturing device comprising:
- a process chamber;
- a feed system for introducing a build material into the process chamber in layers;
- an irradiation unit for selectively solidifying the build material in the process chamber;
- and
- a filter system for purifying a process gas of the additive manufacturing device, the filter system comprising:
- a permanent filter that is regenerable and configured to remain installed during repeated operating cycles;
- and
- a cleaning arrangement configured to clean the permanent filter in situ by a reverse-flow cleaning gas pulse to remove collected particles.
