  • Method and system for monitoring a powder bed process in additive manufacturing
    Patent number: 11964435
    Abstract: There is provided a method of monitoring a powder bed process in additive manufacturing, using at least one processor. The method including: obtaining a first image of a powder bed layer from scanning the powder bed layer in a first scanning direction using a first contact image sensor, the powder bed layer being formed by a powder re-coater arm in the powder bed process and the first contact image sensor being attached to the powder re-coater arm; determining a focus level property of the first image; and detecting non-uniformities in the powder bed layer based on the focus level property of the first image. There is also provided a corresponding system for monitoring a powder bed process.
