Methods and combinations of a curing catalyst with a mold release mixture, which is then subsequently applied to the surface of a mold prior to the application of polyurethane reactants to said mold, where the curing catalyst component has the effect of catalyzing the reaction at the surface of the molded part. This catalysis results in greater reactivity at the surface between reacting portions and lower delamination of the surface of the foam, thereby leading to more attractive skins with a more consistent cell structure, and lower de-mold times due to skins whose nature makes them less likely to adhere to the surface of the mold. These foams will be less likely to tear upon opening of the mold, and production quality and output will be improved.

A method of forming a three-dimensional object, is carried out by (a) providing a carrier and a build plate, the build plate comprising a semipermeable member, the semipermeable member comprising a build surface with the build surface and the carrier defining a build region therebetween, and with the build surface in fluid communication by way of the semipermeable member with a source of polymerization inhibitor; (b) filling the build region with a polymerizable liquid, the polymerizable liquid contacting the build surface, (c) irradiating the build region through the build plate to produce a solid polymerized region in the build region, while forming or maintaining a liquid film release layer comprised of the polymerizable liquid formed between the solid polymerized region and the build surface, wherein the polymerization of which liquid film is inhibited by the polymerization inhibitor; and (d) advancing the carrier with the polymerized region adhered thereto away from the build surface on the build plate to create a subsequent build region between the polymerized region and the build surface while concurrently filling the subsequent build region with polymerizable liquid as in step (b). Apparatus for carrying out the method is also described.

Systems for depositing coatings onto surfaces of molds and other articles are generally provided. In some embodiments, a system is adapted and arranged to cause gaseous species to flow parallel to a filament array. In some embodiments, a system comprises one or more mold supports that are translatable.

A film production method for producing a thin film on a surface of a workpiece, including the steps of: disposing the workpiece in a chamber; supplying a process gas into the chamber with the inside of the chamber being maintained at a predetermined pressure; applying a light having an energy between 3 eV and 10 eV to the surface of the workpiece to cause a photoelectron to be emitted from the surface of the workpiece; and applying an AC electric field to the surface of the workpiece, wherein the AC electric field has an electric field intensity causing a Townsend discharge to occur without generating a glow discharge plasma.

The improved mold assembly for cultured marble molding is provided. The mold assembly can comprise a male mold portion and a female mold portion. The assembly can further comprise a molding tool. The molding tool can have a side wall having an upper curved portion and a lower curved portion. The molding tool can have a bowl portion and an apron portion spaced from the bowl portion by a gap. The molding tool can be constructed from a flexible and/or soft material. The molding tool can facilitate molding of a countertop having at least one seamless curved edge and/or an at least partially seamless sink portion.
