Method and system for printing gradient material by depositing multiple powders on a roller base.
To provide a method for making 3D components having graded material properties.SOLUTION: There are provided method and system of using a roller-based deposition process to place two or more powders at some level of precision to build a multi-material, functionally-graded component. Instead of formulating a liquid ink by dispersing powder feed stocks (metal or ceramic) in some binder-solvent mixtures, there is detailed the use of two different types of fluid deposited in a digital form on a roller surface. The two different types of fluids generate a "wetted pixel" that subsequently can capture a specific powder type with an affinity only to that fluid. Alternatives such as electrostatics, electrophotography, and the like are also provided to be used exclusively or with fluids to create an affine pixel to a particular powder type.SELECTED DRAWING: Figure 2

Thermally curable piezoelectric composites and use thereof in additive manufacturing
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.
