Characterization of resistors created by fused filament fabrication using electrically-conductive filament

摘要

Desktop fused filament fabrication (FFF) printers (3D printers) are ubiquitous rapid prototyping (RP) and additive manufacturing (AM) devices used by small and large companies as well as by hobbyists. Their attractiveness stems from the inexpensive hardware, inexpensive plastic materials, affordable CAD environments, and short training times. This research explores design of resistors created by the FFF printing process using commercially available electrically-conductive carbon black and graphene-based filament. 3D printed resistors are designed, constructed, and characterized. A number of tests are performed resulting in a set of build recommendations. With this novel capability to directly create electrical components integrated into 3D printed physical objects designers can envision and 3D print new and/or improved devices with embedded electronics, which they could not do before.
