  • Fast and effective image inpainting for reticle removal
    Patent number: 10650499
    Abstract: A memory device receives an original input image having at least one horizontal reticle or at least one vertical reticle. The memory device also receives a horizontal reticle mask image for horizontal reticles and/or a vertical reticle mask image for vertical reticles. A processor inpaints three regions: (1) vertical reticles with a horizontal filter, (2) horizontal reticles with a vertical filter, and (3) an intersection of the horizontal and vertical reticles with a two dimensional filter. A single inpainted image is produced. The processor determines whether a maximum change in any one of the first inpainted region, the second inpainted region or the third inpainted region equals or exceeds a predetermined threshold, and if so, repeating the inpainting steps. Once the maximum change in pixel intensity is less than the predetermined threshold the processing stops.

  • Systems and methods for low temperature metal printing
    Patent number: 10648058
    Abstract: A system and method of providing metal comprising objects via additive manufacturing techniques using an RES mixture. The RES process mixes a precursor compound and a chemical agent which thermally decomposes to form typically CO, H2, NHx, or some other reducing agent. Using the RES mixture, the additive manufacturing device reproduces an object from a sliced object model file layer-by-layer. Heat is applied to the patterned RES mixture to thermally decompose the chemical agent and reduce the precursor compound to a reduced metal species. This heating and reduction transforms the RES mixture from a general paste having little to no shear strength to an solid form exhibiting a much greater shear strength, allowing layer-by-layer generation of 3D object components.
