Abstract: Laminates comprising at least one film and a nonwoven substrate, wherein the film comprises a polymeric composition comprising at least about 50% of one or more styrenic block copolymers, olefinic block copolymers, or combinations thereof; wherein the nonwoven substrate comprises at least one layer of spunbond material comprising ribbon-shaped fibers, wherein the laminate comprises ultrasonic bonds, thermal bonds, or combinations thereof and which have advantageous properties relative to a comparative laminate in which the nonwoven comprises non-ribbon shaped fibers.

Abstract: A coated print bed for a 3D printer having a permanent print-surface coating permanently secured to a print bed substrate plate, having a smooth, planar surface that provides an adhesive interface layer between a first layer of an applied plastic print material and the coated print bed. The coating contains a matrix-forming compound, such as a solvent- or water-based epoxy resin, an adhesive material, and optionally a filler. The user can print a series of print object directly onto the permanent print surface coating of the coated print bed, without having to refresh or refurbish the print surface, such as by applying to the print bed surface a temporary coating such as painter's tape, or a liquid adhesive.
