Abstract
The present invention relates to a device for manufacturing components layer by layer by locally selective solidification of material powder in a process area by electromagnetic radiation or particle radiation. The device comprises a powder supply for supplying powder P to the process area. The powder supply comprises a powder conduit which is connected to a funnel section 1, and at least one controllable shut-off valve V1, V2 which is arranged downstream of the funnel section 1 in a powder flow direction R. The device enables inline determination of the pourability characteristics of the powder that is actually used.
Claims16
A device for manufacturing components layer by layer by locally selective solidification of material powder in a process area by electromagnetic radiation or particle radiation, comprising:
- a powder supply for supplying powder to the process area, wherein the powder supply is comprising:
- a powder conduit connected to a funnel section, and
- at least one controllable shut-off valve which is arranged downstream of the funnel section in a powder flow direction,
- wherein for determining pourability characteristics of the powder at least one sensor is provided for time-dependent determination of mass of the powder which is disposed in the funnel section or which is removed from the funnel section, and
- wherein the at least one sensor is provided in the funnel section.
