POWDER APPLICATION ARRANGEMENT COMPRISING A CAMERA

摘要

A powder application arrangement for use in an apparatus for manufacturing work pieces by irradiating powder layers with electromagnetic radiation or particle radiation, the powder application arrangement comprises a carrier adapted to receive layers of a raw material powder and a work piece made of the raw material powder by a generative layer construction method. The powder application arrangement further includes a powder application device configured to deposit the raw material powder onto the carrier At least one camera is attached to the powder application device in such a position that it is capable of acquiring images of at least one of a surface of a raw material powder layer applied onto the carrier by means of the powder application device and a surface of the work piece made of the raw material powder by a generative layer construction method while the powder application device is moved across the carrier.

1. A powder application arrangement or use in an apparatus for manufacturing work pieces by irradiating powder layers with electromagnetic radiation or particle radiation, the powder application arrangement comprising:
a carrier adapted to receive layers of a raw material powder and a work piece made of the raw material powder by a generative layer construction method, a powder application device configured to deposit the raw material powder onto the carrier, the powder application device being movable back and forth across the carrier, and at least one camera attached to the powder application device in such a position that it is capable of acquiring images of at least one of a surface of a raw material powder layer applied onto the carrier by means of the powder application device and a surface of the work piece made of the raw material powder by a generative layer construction method while the powder application device is moved across the carrier.
