TEMPERATURE REGULATION FOR A DEVICE FOR THE ADDITIVE MANUFACTURING OF COMPONENTS AND CORRESPONDING PRODUCTION METHOD

摘要

The present invention relates to a device for the additive manufacturing of components (4) by selectively irradiating a powder bed (6), the device having a working chamber (1) in which at least one powder bed chamber (2) and at least one radiation source are arranged such that the radiation source can irradiate a powder in the powder bed chamber (2), and wherein the device comprises at least one induction coil (3, 13) such that the powder bed and/or a component, which is generated by irradiating (7) the powder bed, can be at least partially inductively heated.

主权项

1. A device for the additive manufacturing of components (4) by selectively irradiating a powder bed (6), wherein the device has a working chamber (1), in which at least one powder bed chamber (2) and at least one radiation source are arranged such that the radiation source can irradiate a powder in the powder bed chamber (2), and wherein the device comprises at least one induction coil (3, 13), so that the powder bed and/or a component, which is generated by irradiation (7) of the powder bed, is at least partially inductively heated,
wherein the induction coil (3, 13) can be displaced relative to one or a plurality of powder bed chambers (2) and the device further comprises a temperature measurement device for measuring the temperature at at least one point of the powder bed and/or the component to be generated, and a regulating device for regulating the operating parameters of the induction coil and/or the radiation source, wherein the regulating device receives the temperature measured by the temperature measurement device as a control variable and the temperature measurement device is designed such that the at least one measurement point is fixed relative to the position of the induction coil and/or the beam of the radiation source at least with respect to one spatial direction.
