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 polymer material comprising at least one thermoplastic polymer, and a plurality of piezoelectric covalently bonded to the at least one thermoplastic polymer and dispersed in at least a portion of the polymer material. The compositions are extrudable and may be pre-formed into a form factor suitable for extrusion. Additive manufacturing processes using the compositions may comprise forming a printed part by depositing the compositions layer-by-layer.

Abstract: User identification information is received through a user interface device. A processor device supplies the user identification information through an input/output device to an external computerized device to receive, in response, external authorization to use features of an apparatus. The user interface device outputs a menu having options to create a local account based on the external authorization and, in response, receives instructions to create a local account using the processor device. The local account is created based on the instructions being received using the processor device. The local account is stored in a memory device. After creation of the local account, the processor device generates local authorization to use the features of the apparatus based on the user identification information matching information in the local account stored in the memory device, without contacting the external computerized device for the external authorization.
