Abstract: A method and apparatus for additive manufacturing that includes a material guide for directing a supply of working material and a plurality of rollers for advancing the working material. An electromagnetic heater is provided to heat and deposit molten working material as a new supply of working material is forced through the material guide.

Abstract: A method and apparatus for additive manufacturing that includes a material guide for directing a supply of working material. An advancement mechanism comprising one or more pistons, pushers, plungers and/or pressure regulation systems are positioned behind at least a portion of the supply of working material for advancing the working material forward. The working material is heated using an electro-magnetic heating element and the melted or molten working material is deposited from a tip positioned at an end of the material guide.

Abstract: A method for producing a bonded permanent magnet by additive manufacturing, the method comprising: (i) incorporating components of a reactive precursor material into an additive manufacturing device, the reactive precursor material comprising an amine component, an isocyanate component, and particles having a permanent magnetic composition; and (ii) mixing and extruding the crosslinkable reactive precursor material through a nozzle of the additive manufacturing device and depositing the extrudate onto a substrate under conditions where the extrudate is permitted to cure, to produce a bonded permanent magnet of desired shape. The resulting bonded permanent magnet and articles made thereof are also described.

Abstract: A method of building a free standing or building wall using prefabricated wall panels (10, 12, 14) wherein the assembly is accomplished at a factory from traditional or conventional building bricks or blocks. Each panel has an integral support means (26) to resist separation of the bricks or blocks when lifted for transport. A joint element (118) is provided between adjacent edges of adjacent panels and serves a labyrinth seal (102) with interleaved seal elements extending lengthwise of the joint. Springs (124) act between opposite sides (120, 122) of the joint so that it is resiliently compressed to accommodate differing spacings between the panels. A thermal insulation compartment (126, 128) is provided between the joint elements.
