摘要:
Process, materials, and equipment for producing three-dimensional objects from a particulate material by melting and adhering, for example, by fusion or sintering, portions of the particulate material.
摘要:
A materials system, kit, and methods are provided to enable the formation of articles by three dimensional printing. A method includes providing a particulate material comprising a plurality of adjacent particles, the particulate material including an aqueous-insoluble thermoplastic; applying to at least some of the plurality of particles an aqueous fluid binder in an amount sufficient to bond those particles together to define an intermediate article; and immersing the intermediate article in a liquid infiltrant medium to define a final article.
摘要:
A method for producing a solid optical system with embedded elements is provided. The embedded elements may include inorganic, polymer, or hybrid lenses, mirrors, beam splitters and polarizers, or other elements. The embedding material is a transparent high quality optical polymer.
摘要:
A fabrication process and apparatus for producing three-dimensional objects (36) by depositing a first polymer layer, printing a first ink layer on to the first polymer layer (34), depositing a second polymer layer on to the first ink layer, and printing a second ink layer on to the second polymer layer. The deposition and printing steps may be repeated until a three-dimensional object (36) is formed. The inks used to form at least one of the first and second ink layers may include dyes or pigments so that the three-dimensional object may be a colored three-dimensional object.
摘要:
Materials system, kit, and methods are provided to enable the formation of articles by three dimensional printing. The kit includes (i) a substantially dry particulate material including an aqueous-insoluble thermoplastic particulate material, plaster, and a water-soluble adhesive; (ii) an aqueous fluid binder, and (iii) an infiltrant.
摘要:
A casting method, rather than injection molding, to produce polymer optical components and systems is provided. The casting process controls shrinkage and stress, thus providing both high bulk uniformity and high quality, accurate surfaces, by incorporating polymer films into the mold. The films may remain incorporated into the part or may optionally be removed from the part after removal from the mold. In addition, the incorporation of separately produced components within the cast part is also provided, eliminating post-casting assembly manufacturing steps.
