  • IDENTIFYING SUBSTRATE WASTE SITES
    Publication number: 20230258678
    Abstract: In one example in accordance with the present disclosure, a system is described. The system includes a fluidic die to advance across an ejection path relative to a substrate. The fluidic die includes a channel to contain a portion of a sample fluid, a sensor to detect passage of a particle within the sample fluid into the channel, and an ejection device. The ejection device is to eject the particle. The system also includes a controller. The controller identifies discrete locations along the ejection path as waste sites as the fluidic die advances along the ejection path. This is done by 1) classifying the particle as a target particle or a non-target particle, 2) upon identification of a target particle, ejecting the target particle to a target site of the substrate, and 3) upon identification of a non-target particle, ejecting the non-target particle to a waste site.

  • DETERMINING THAT PRINTING A 3D OBJECT FROM A SELECTED BUILD MATERIAL IS EXPECTED TO RESULT IN A DEFECT
    Publication number: 20230234295
    Abstract: A method includes receiving an object model describing a geometry of a three-dimensional, 3D, object for printing by a 3D printer, and build material data indicating a selected build material to be used in printing the 3D object by the 3D printer. A volume to surface area ratio of the object model is calculated. In response to the volume to surface area ratio being greater than a first predetermined threshold value for the selected build material, it is determined that printing the 3D object by the 3D printer from the selected build material is expected to result in a defect in the 3D object.
