Claim Text:
1. A method of forming a structural laminate having a selected resistance to a first stress applied in a selected first stress direction relative to the structural laminate, the method comprising: receiving first and second sheets; depositing on the first sheet a selected volume of toner to form a first deposited toner pattern, the first deposited toner pattern being disposed over a selected first surface area of the first sheet and extending normal to the first sheet by a selected first height; depositing on the second sheet a selected volume of toner to form a second deposited toner pattern, the second deposited toner pattern being disposed over a selected first surface area of the second sheet and extending normal to the second sheet by a selected second height; moistening the first and second sheets; bringing the second sheet, or second deposited toner thereon, into contact with the deposited toner pattern; forming the structural laminate by fixing the deposited toner patterns to produce a fixed toner pattern that adheres the second sheet to the first sheet, wherein the fixed toner pattern includes one or more first contiguous regions of toner extending in a direction within about 45° of the first stress direction, so that the one or more first contiguous regions resist the first applied stress; drying the first and second sheets after the forming step, wherein the drying step includes retaining the fixed sheets in a selected shape while drying the sheets.
