Additive Manufacturing (AM) offers the opportunity to quickly design and make prototypes that would otherwise require multiple step processing (lithography, nanoimprint…). So far, two-photon polymerization is the leading technology for manufacturing micron sized objects with nanometric resolution. However, thise technique requires photosensitive material, that polymerizes through two-photon absorption, limiting the versatility of the the technology NanoPrint is a direct AM technique, offering resolutions down to a few tens of nanometers in width and a few nanometers in height, bridging the manufacturing gap exposed by the historical industry trend of the past 40 years. It is not material specific, as any ink can be deposited, minding some adjustments in the printing parameters (colloidal metals, polymers, sensitive biological material). Another major advantage of this solution is the non-alteration of the ink by an external energy source (UV, laser…). Inspired by the long-established know-how in AFM at Micromégas Team, NanoPrint provides a nanometric manufacturing technology with unprecedented versatility and resolution. As opposed to conventional AFM techniques, our method uses a macroscopic resonator (tuning fork) allowing us to attach a larger capillary, without much excessively disturbing the oscillation properties, that are crucial for the deposition. We believe this technology will open new opportunities for the semiconductor (maskless lithography, interconnects...), molecular diagnosis (lab-on-chip, point of use), and microled (augmented and virtual reality) industries. This project emerged from the NANOSOFT ERC project, while working on the nanomanipulation of nanotubes and nanopipettes.
