ADDITIVE MICROMANUFACTURING PROCESS
Localized Electrodeposition of Pure Metals
ELECTROCHEMICAL DEPOSITION µAM
Exaddon's additive micromanufacturing technology (µAM) is based on electrochemical deposition:
2. A precisely regulated air-pressure pushes a liquid containing metal ions through a microchannel inside the iontip. The liquid flow is very small - as low as femtoliters per second.
3. At the end of the microchannel, the ion containing liquid is released onto the print surface. The print surface must be conductive; we use materials such as Cu, Au, PEDOT, and ITO.
4. The dissolved metal ions are then electrodeposited into solid metal atoms.
The forces acting on the iontip can be measured optically, and are used as feedback. This allows the system to detect which voxels of the object have already been printed. This optical force feedback provides real-time process control.
