Manufacturing Microcoils and Helices with µAM

A metal microcoil 3D printed for medical research - produced by Exaddon for Harvard Medical School

Manufacturing coils and helix structures with a diameter less than 300 micrometers is a complex challenge which is hardly addressed by conventional methods. Thanks to our additive micromanufacturing technology, coils down to 10 micrometers in diameter are possible using standard printing nozzles. Using custom nozzles, the diameter can go even smaller.

The CERES µAM print system can print coils in isolation or in array, with overall coil diameter, strand diameter, or pitch all able to be customized. 


  • Structures printed directly onto contact pads

  • Wide range of designs possible

  • Pure, high quality copper or gold (other metals possible)

  • Excellent conductivity (~87% of bulk copper)

  • Excellent adhesion to the substrate

  • More complicated designs feasible:
    - Planar coils
    - Intertwine multiple coils
    - Strands can have different diameters
