Can you print circuit boards?

This is a great idea. The technology isn’t ready though.
The filament needs to be debound and sintered in order to be conductive.
The plastic in the filament is what makes it print like regular PLA and also prevents the movement of electricity through the filament and green print. The metal particles would need to be joined together through sintering to create that conductivity.

Why not print the circuit with dual extrusion and use copper and ceramic Filament?

Have tossed around the idea, but haven’t gotten around to it yet (so many projects too little time)
