    These capacitors are embedded in the body of the additively manufactured printed circuit boards (PCB), saving space and eliminating the need for assembly.
    Nano Dimension’s testing with capacitors of different 3D dimensions have deliverd repeatability results which show less than 1% variance.
    The technology uses the same dielectric and metal traces as in the additively manufactured PCB yielding capacitors with a capacitance range from 0.1nF to 3.2nF. The successful results are based on over 260 tests with 30 different additively manufactured capacitors dimensions.
    By integrating capacitors using additive manufacturing, electronics designers and manufacturers can avoid what is often a time consuming, multi-step assembly process, as the DragonFly prints the entire capacitor and PCB in one print job.

    This allows companies to reduce the fabrication time and overcome many of the challenges imposed by traditional production techniques.
    Additively manufacturing capacitors within the inner layers of circuits also can free space to meet the ever-increasing trend towards miniaturization and flatness of electronic devices for consumer, industrial and military applications. With extra space, designers may pack more functionality on the circuit boardand shrink component size – all without compromising reliability.
    Capacitors of this kind are primarily used to filter electrical noise and ripple voltage for a wide range of applications, including RF transmission lines, audio processing, radio reception and power circuit conditioning.
