Abstract: A heating circuit assembly and method of manufacture includes an electrically conductive heating element having a pattern. An electrically non-conductive substrate is additive manufactured and secured to the element for structural support. The substrate has a topology that generally aligns with the pattern of the element thereby reducing the assembly weight and minimizing substrate material waste.

Abstract: The present disclosure relates to systems, methods and resins for additive manufacturing. In one embodiment, a method for additive manufacturing of a ceramic structure includes providing a resin including a preceramic polymer and inorganic ceramic filler particles dispersed in the preceramic polymer. The preceramic polymer is configured to convert to a ceramic phase. The method includes functionalizing inorganic ceramic filler particles with a reactive group and applying an energy source to the resin to create at least one layer of the ceramic phase from the resin.

Abstract: A method for fabricating a ceramic material includes impregnating a porous structure with a mixture that includes a preceramic polymer and a filler. The filler includes at least one free metal. The preceramic polymer material is then rigidized to form a green body. The green body is then thermally treated to convert the rigidized preceramic polymer material into a ceramic matrix located within pores of the porous structure. The same thermal treatment or a second, further thermal treatment is used to cause the at least one free metal to move to internal porosity defined by the ceramic matrix or pores of the porous structure.

Abstract: A system for direct writing a conformal or free-form magnet includes producing a magnetic ink compound by mixing an photopolymer base and a magnetic material powder, extruding a layer of the magnetic ink compound through a nozzle on to a target substrate to form a layer, soft-curing the layer by exposing the layer to a first light, repeatedly extruding a layer and soft-curing the layer, then post-curing the magnet by exposing the magnet to a second light and an elevated temperature.
