Patents by Inventor Itay Barel

Itay Barel has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11597157
    Abstract: A design with multiple instances of a three-dimensional article is printed by first defining a unit cell that includes a single instance of a three-dimensional article that repeats in the design along with its nearest neighbor elements in both a plane of a build plate of a target printer on which the design is to be printed and a plane orthogonal thereto. The design is represented in an output file of a design application and a slicer application then generates instructions to manufacture the design by the target printer. The instructions (g-code) include directions to print, for each of a specified number of layers a number of instances of the unit cell that can be accommodated within a build envelop of the target printer per layer as determined by said slicer application. The design is printed by the printer according to the instructions from the slicer application.

  • Patent number: 11491728
    Abstract: An optimal printing speed and orientation for an object to be manufactured using an additive manufacturing process in which a photo-curable resin is cured through exposure to radiation are estimated by determining, for pixel maps defining cross-sections of the object, a critical size of a convolution kernel which provides an activation map having a maximum activation pixel value less than or equal to a predetermined threshold value. For each respective pixel map, a printing time is estimated as a function of adjusted base lift velocity and base lift height of the printing apparatus. The optimal printing speed and orientation are then estimated as a minimum value of a sum of a function of printing times for all respective pixel maps of the cross-sections of the object at each of a plurality of possible orientations of the object.
