  • Method for detecting defects in an additive manufacturing powder layer deposited on a working area
    Patent number: 12502715
    Abstract: A method for detecting defects in a layer of additive manufacturing powder deposited on a work zone, comprises the steps of: i. acquiring an image of a layer of additive manufacturing powder, ii. determining a discrete spectral representation of the image acquired, iii. filtering the discrete spectral representation of the image acquired in frequency terms, iv. determining a filtered image from the filtered discrete spectral representation of the image acquired, and v. analyzing the filtered image so as to detect defects.

  • Device for the actively-controlled and localized deposition of at least one biological solution
    Patent number: 8617406
    Abstract: The invention relates to a device for the actively-controlled deposition of microdrops of biological solutions. The inventive device includes at least one flat silicon lever comprising a central body and an end area which forms a point, a slit or groove being disposed in said point. The invention is characterized in that it also comprises at least one metallic track which is disposed on one face of the central body and which runs alongside said slit or groove at least partially. The invention also relates to a method of producing the inventive device and a method for the active-controlled deposition and sampling of microdrops of biological solutions using said device.
