Abstract

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 plurality of piezoelectric particles and a polymer material comprising at least one thermoplastic polymer and at least one thermally curable polymer precursor. At a sufficient temperature, the at least one thermally curable polymer precursor may undergo a reaction, optionally also undergoing a reaction with the piezoelectric particles, and form an at least partially cured printed part. The piezoelectric particles may be mixed with the polymer material and remain substantially non-agglomerated when combined with the polymer material. The compositions may define a form factor such as a composite filament, a composite pellet, or an extrudable composite paste, which may be utilized in forming printed part by extrusion, layer-by-layer deposition, and thermal curing.
