Converting base metals into noble ones is something many have been trying for ages already. With FluidFM, Cytosurge has gone beyond, by converting ‘water’ into finite noble metal sub-micron objects. With the FluidFM µ3Dprinter various metals such as Ag, Cu, Au, and Pt can be printed.

Cytosurge AG, an ETH Zürich spin-off company,  is using a new method of printing copper, silver and gold metal objects at room temperature out of an aqueous solution. The FluidFM technology opens a new world for metal object manufacturing and enables research opportunities in fields such as surface modification, microelectronics, semiconductors, sensors, microbots, material science and many other fields.

FluidFM µ3Dprinter

At the forefront of nanotechnology, additive manufacturing, life sciences and single cell biology, FluidFM µ3Dprinter is the world’s first 3D printer that is capable of delivering sub-micron resolution in direct metal printing, while offering scalability and good prospects in both production cost and speed.

High-precision surface modification processes can be executed by printing ultra-thin or structured objects and by depositing multiple metals at the target surface. Virtually any design can be offered to the system, including overhanging structures with 90 degree angles, without support structures or post processing steps.

At the IDTechEX Show in Berlin earlier this year – where emerging technologies are presented – Cytosurge won the ‘Best Development in 3D Printing Award Europe 2017’ an award for their FluidFM µ3Dprinter.
