摘要： The present invention provides methods, processes, and systems for the manufacture of three-dimensional articles made of polymers using 3D printing. A layer of prepolymer is deposited on a build plate to form a powder bed. Then, solutions of first and/or second binding agents are printed on the powder bed in a predetermined pattern. After a predetermined period of time, sequential layers are printed to provide the three-dimensional article. The removable binding agent is then removed. The three-dimensional object can be cured to produce the three-dimensional article composed of the final polymers.

摘要： A method for forming a fire-retardant thermoplastic composite panel includes mixing a thermoplastic polymer with a fire-retardant additive to form a fire-retardant polymer composition and assembling a composite layup of a plurality of first layers and a plurality of second layers by alternatingly positioning the plurality of first layers and the plurality of second layers with each first layer including a fire-retardant polymer composition film of the fire-retardant polymer composition and each second layer including a carbon-fiber fabric. The method further includes compression molding the composite layup to form the fire-retardant thermoplastic composite panel.

摘要： The disclosure relates to polymer-containing composite materials and to unusually low-pressure consolidation methods for forming composite parts from such materials. More specifically, for example, the disclosure relates to use of a certain “PEEK-PEDEK” copolymer in low-pressure consolidation methods, using as little as 1 bar pressure (or using atmospheric pressure acting on a consolidation that is held under vacuum) to provide composite parts that are substantially void-free.

摘要： A method and an arrangement for producing a workpiece using additive manufacturing techniques involve pre-process, in-process and post-process measurement in order to determine individual characteristics of one or more workpiece layers. In particular, dimensional and/or geometrical characteristics of a workpiece layer are measured before the next workpiece layer is produced. Advantageously, production parameters are controlled in response to individual material characteristics determined prior to the production process. Also advantageously, measurement results are fed back into a production process in order to increase accuracy, reliability, repeatability and precision of the production process.

摘要： A three-dimensional object comprises stacked substrate layers infiltrated by a hardened material comprising engineered powder that is transformed into a substance that flows and subsequently hardens into the hardened material in a spatial pattern that infiltrates positive regions, and does not infiltrate negative regions, in the substrate layers. The powder may be emulsion aggregation powder, chemically-produced toner powder, or a combination. It may be a thermoplastic or thermosettable polymer and may include nylon, elastomers, polyolefins, polyethylene, polyether ether ketone, polyimide, polyetherimide, polyphenylene sulfide, polystyrene, polypropylene, polymethyl methacrylate, and polyaryletherketone, or a combination. The powder particles may have a pre-specified controlled shape and/or a non-homogenous composition. Surface treatments and/or additives may be used to control powder flow and charge distribution. Each substrate layer may be a sheet-like structure comprising fibers held together by binder. The binder may include sodium silicate.
