Parts made by additive manufacturing are often structural in nature, rather than having functional properties conveyed by a polymer or other component present therein. Printed parts having piezoelectric properties may be formed using compositions comprising a polymer matrix comprising a first polymer material and a second polymer material that are immiscible with each other, and a plurality of piezoelectric particles substantially localized in one of the first polymer material or the second polymer material. The piezoelectric particles may remain substantially non-agglomerated when combined with the polymer matrix. The compositions may define a form factor such as a composite filament, a composite pellet, or an extrudable composite paste. Additive manufacturing processes using the compositions may comprise forming a printed part by depositing the compositions layer-by-layer.

Parts made by additive manufacturing are often structural in nature, rather than having functional properties conveyed by a polymer or other component present therein. Printed parts having piezoelectric properties may be formed using compositions that are extrudable and comprise a plurality of piezoelectric particles and a plurality of carbon nanomaterials dispersed in at least a portion of a polymer material. The piezoelectric particles may remain substantially non-agglomerated when combined with the polymer material. The polymer material may comprise at least one thermoplastic polymer, optionally further containing at least one polymer precursor. The compositions may define an extrudable material that is a composite having a form factor such as a composite filament, a composite pellet, a composite powder, or a composite paste. Additive manufacturing processes using the compositions may comprise forming a printed part by depositing the compositions layer-by-layer.

The present invention relates to a protective liner coating. The protective liner coating may comprise one or more solvents, an antioxidant, a first pigment, barium sulfate, a wetting agent, a rheological additive, a surfactant, a second pigment, and a plurality of resins. The protective liner coating may be used for secondary containment protection from chemicals and other toxic substances.

This invention provides resin formulations which may be used for 3D printing and pyrolyzing to produce a ceramic matrix composite. The resin formulations contain a solid-phase filler, to provide high thermal stability and mechanical strength (e.g., fracture toughness) in the final ceramic material. The invention provides direct, free-form 3D printing of a preceramic polymer loaded with a solid-phase filler, followed by converting the preceramic polymer to a 3D-printed ceramic matrix composite with potentially complex 3D shapes or in the form of large parts. Other variations provide active solid-phase functional additives as solid-phase fillers, to perform or enhance at least one chemical, physical, mechanical, or electrical function within the ceramic structure as it is being formed as well as in the final structure. Solid-phase functional additives actively improve the final ceramic structure through one or more changes actively induced by the additives during pyrolysis or other thermal treatment.
