Capricate: A Fabrication Pipeline to Design and 3D Print Capacitive Touch Sensors ...
summary
A fabrication pipeline turns a 3D model into a single-pass printed object with embedded capacitive sensors using a dual-extrusion commodity 3D printer and a conductive carbon ABS filament. Two sensor strategies are implemented: curved-surface electrodes that follow geometry and flat-bottom electrodes whose per-electrode threshold is calibrated from modeled overlay thickness via a measured SNR material function. Printing traces aligned with current flow yield twice as conductive traces; experiments and several example applications validate the approach.
