  • Methods and devices for counteracting stresses during 3D printing
    Patent number: 9833953
    Abstract: Methods of 3D printing an object with reduced curl on at least one surface that contacts a print plate are described herein. For example, in some embodiments, a method of 3D printing an object comprises depositing build material to form a first layer of a 3D printed object and depositing build material in a predetermined pattern to form a first layer of a skirt in contact with the 3D printed object. Depositing build material to form the first layer of the skirt comprises 3D printing a first layer of a sidewalk that substantially surrounds at least a portion of a perimeter of the 3D printed object and 3D printing a first layer of a perforated interface between the sidewalk and the perimeter of the skirt.
