Abstract
A powder application apparatus is provided for use in a device for manufacturing work pieces by exposing powder layers to electromagnetic radiation or particle radiation. The powder application apparatus comprises a first powder storage provided in a first part of the powder application apparatus and configured to receive and store raw material powder. The powder application apparatus further comprises a first powder supply channel provided in a second part of the powder application apparatus and configured to discharge raw material powder from the first powder storage onto a carrier located below the apparatus. A first channel opening/closing element is configured to be moved between a first position to allow the discharge of raw material powder from the first powder storage onto the carrier, and a second position in which the discharge of raw material powder from the first powder storage onto the carrier is presented.
