3D Printed Capacitors

Parallel plate capacitors can be printed using Electrifi as the conductive material and other dielectric polymers as the separator. The capacitance scales linearly with the number of stacked layers.

3D Printed Inductors

The 3D printed 9-turn spiral inductor is able to receive wireless power from a commercial wireless phone charger to light up an LED.

3D Printed RF Filters

The fully 3D printed high-pass filter circuit consisting of a 60 pF capacitor and a 2.2 μH inductor filters out low frequencies with a cutoff frequency at approximately 7 MHz.

3D Printed Horn Antennas

Horn antennas are not cheap. With Electrifi, you may 3D print horn antennas with a comparable performance at a fraction of the cost.

3D Printed Cavity Antennas

This hybrid metasurface cavity antenna (15 cm×15 cm×4 cm) is a low-cost option for computational microwave imaging.

3D Printed HDTV Antennas

This fractal HDTV antenna is such an example of demonstrating how Electrifi can be practically used with your 3D printer at home.

3D Printed Metamaterials

Microwave metamaterials are engineered materials designed to interact with electromagnetic waves. 3D printing with Electrifi exploits the third dimension of the design space to better achieve desired electromagnetic properties.

3D Printed Batteries

Electrifi and other functional materials are coupled to print batteries with arbitrary geometries to accommodate increasingly small and odd-shaped electronic devices.

Electroplating 3D Printed Objects

Selective deposition of copper can be achieved through electroplating of the inductive coil printed with Electrifi and PLA, resulting in a 2000x increase in surface conductivity, and thus a 1740x more efficient energy storage of the coil.

3D Printed Metasurface Antenna

We demonstrate a 3D printed holographic metasurface antenna for beam-focusing applications at 10 GHz within the X-band frequency regime.

Selective Electroplating for 3D-Printed Electronics

A hybrid process based on 3D printing followed by electroplating on highly conductive thermoplastic filament is used to manufacture 3D circuit boards and electronic packaging.
