Method for operating a manufacturing device and manufacturing device for the additive manufacturing of a component from a powder material

A manufacturing device for the additive manufacturing of a component from a powder material, the manufacturing device comprising:

• a construction location which is configured for the additive construction of a component from the powder material on the construction location;
• an optical recording device configured to take optical recordings of the construction location;
• and
• a control device which is configured to:
• locally evaluate at least one optical recording, taken by the optical recording device, of a working powder layer of the powder material on the construction location;
• and examine the working powder layer for local coating errors using the local evaluation of the at least one optical recording.
