  • Methods and systems for shell formation in 3D printing
    Patent number: 11625902
    Abstract: A method for generating or enhancing a shell for a printed three-dimensional (3D) object includes converting a 3D print file representing the 3D object to at least one vector file representing the 3D object; using a vector trapping algorithm on the at least one vector file to generate or enhance the shell in the at least one vector file; processing the at least one vector file with the shell to produce at least one rasterized vector file; and printing, using the at least one rasterized vector file, the 3D object with the shell.
    Type: Grant

  • Methods and systems for embedding information into text of printable documents by altering one or more of the glyphs to change a shape of the glyphs
    Patent number: 10419636
    Abstract: Information can be encoded into text of a printable document or other printed material. The text includes glyphs, where each glyph corresponds to a text character. Additional information can be encoded into the text by altering one or more of the glyphs to change a shape of the one or more of the glyphs, so that each of the altered glyphs still corresponds to the text character to which the glyph corresponded prior to alteration and the altered glyph further contains a portion of the additional information encoded by the changed shape.
