Abstract: A method of rendering data for addressable dispensing of material over a working surface, comprises: receiving input image data arranged grid-wise over a plurality of picture-elements; generating an initial map describing a distance field and having a plurality of map-elements each storing distance information corresponding to one picture-element; for each picture-element of at least a portion of the picture-elements: linearly scanning the map independently along a first axis and along a second axis, and updating a respective map-element based on values of map-elements visited during the scan. The distance field can include distances defined perpendicularly to the working surface.

Abstract: There is provided a method of defect detection on a specimen and a system thereof. The method includes: obtaining a runtime image representative of at least a portion of the specimen; processing the runtime image using a supervised model to obtain a first output indicative of the estimated presence of first defects on the runtime image; processing the runtime image using an unsupervised model component to obtain a second output indicative of the estimated presence of second defects on the runtime image; and combining the first output and the second output using one or more optimized parameters to obtain a defect detection result of the specimen.

Abstract: There is provided a method of automated defects' classification, and a system thereof. The method comprises obtaining data informative of a set of defects' physical attributes usable to distinguish between defects of different classes among the plurality of classes; training a first machine learning model to generate, for the given defect, a multi-label output vector informative of values of the physical attributes, thereby generating for the given defect a multi-label descriptor; and using the trained first machine learning model to generate multi-label descriptors of the defects in the specimen. The method can further comprise obtaining data informative of multi-label data sets, each data set being uniquely indicative of a respective class of the plurality of classes and comprising a unique set of values of the physical attributes; and classifying defects in the specimen by matching respectively generated multi-label descriptors of the defects to the multi-label data sets.

Abstract: A method of additive manufacturing for producing a 2-part mold suitable for use in injection molding, comprises: obtaining a computerized 3D representation of a 2-part mold (3D mold); delimiting one or more regions within the 3D mold; assigning a material or a combination of materials to each delimited region which is different from different from materials used in other delimited regions or outside the delimited regions; and producing the 2-part mold by additive manufacturing; wherein the delimiting comprises carrying out an offset from a surface of the 3D mold which is intended to be in contact with injected material, and wherein the offset is carried out within the solid part of the 3D mold.
