Nano Dimension's DragonFly IV system is a 3D printer capable of printing dielectric and conductive structures (silver) with an accuracy of 50 μm.

The equipment has a dielectric with a lower constant than that of the FR4 and is able to create conductive structures in 3D.

The DragonFly IV can be used to prototype fast circuit boards, non-standard conductive structures or exotic printed circuit boards.

The printer has two print heads, one for conductive ink (CI) and one for dielectric ink (DI), which simultaneously print the inks to be accurately deposited on the substrate to form the device.

Design files (Gerber and Excellon, ODB++ and STL) are used to create print jobs that are sent to the DragonFly IV queue for printing.
