Abstract: Systems and methods in which a material or materials (e.g., a viscous material) are printed or otherwise transferred onto an intermediate substrate at a printing unit(s). The intermediate substrate having an image of material printed thereon is subsequently transferred to a sample building unit, and the image of material is transferred from the intermediate substrate to a sample at the sample building unit. Optionally, the printing unit(s) includes a coating system that creates a uniform layer of the material on a donor substrate, and the material is transferred from the donor substrate onto the intermediate substrate at the printing unit(s). Each of the printing units may employ a variety of printing or other transfer technologies. The system may also include material curing, heating, sintering, ablating, material filling, imaging and cleaning units to aid in the overall process.

Abstract: A method of repairing a component using an additive manufacturing process is presented. The method includes submerging the component into a powder bed so that a portion of the component to be repaired is level with a surface of the powder bed and a protruding portion of the component protrudes above the surface of the powder bed, positioning a split wiper that includes a first wiper segment and a second wiper segment in the powder bed at the surface, advancing a quantity of powder by translating the first wiper segment and the second wiper segment across the surface of the powder bed, and directing a laser beam across the surface to fuse powder particles of the powder bed to the underlying substrate forming a layer of the component. Each of the first wiper segment and the second wiper segment follow a different contour of the protruding portion at the surface.

Abstract: Methods and systems for additive manufacturing can include a modular spreader unit including multiple spreaders that collectively span the width of a large build area. The spreaders can be arranged in offset rows so that spreaders in a second row cover gaps between spreaders in a first row. The spreaders can be secured with quick release mechanisms for rapid replacement and adjustment during service intervals.

Abstract: A system and method are described for post-processing a 3D printedcomponent. For example, support structures for the 3D printed component may beremoved during post-processing. ln the system and method, a first image of acomponent is stored in memory. A second image of a 3D printed componentcorresponding to the component is also captured. One or more cutting pathsbetween the 3D printed component and the support structures is then determinedbased on the first image and the second image. The 3D printed component maythen be autonomously separated from the support structures by cutting through thecutting path.
