CoolingUnit Tutorial

Picturing the surface of the human body as no different from that of a car or personal computer. In the future there might be an increasing need to cool embedded implants. Using 3D printed elastic resin, real PC fans are “installed” onto the surface of skin.


Tools and Materials

  • Elastic 50A Formlabs elastic resin tank

  • Fan

  • Battery

  • Switch connector

  • Wires

    • Silicone Cover Stranded-Core Wire - 50ft 30AWG White

    • Silicone Cover Stranded-Core Wire - 50ft 30AWG Black


Construction Steps

Resin printing

  1. Open the .stl in PreForm and print it on a Formlabs Form 3 printer in elastic 50A resin

  2. Soak in isopropyl alcohol bath after print

Circuit connection

  1. Desolder wires on the fan, solder silicone-coated stranded wire to the fan, note the polarity: white for + and black for -

  2. Fitting soldered fans into the 3D print

  3. Feed the wires through the channels in the 3D print

  4. Solder the wires to the battery connector, white wires -> SW, black wires -> GND

Apply:

  1. Clean with alcohol swab as needed

  2. Use DUO eyelash glue to apply the CoolingUnit on skin
