Have you ever seen a 3D printer at the micro / nano scale? It can easily print ultra-small, ultra-high-precision 3D models, which are thinner than human hair, and the models are so small that they cannot be discerned by the human eye.
Micro-nano 3D printed spiral structure is thinner than hair
On August 3, 2018, we were informed that Beijing U-Smart has introduced the micro-nano 3D printer “FluidFM μ3Dprinter” developed by Swiss Cytosurge AG for the first time to the Chinese market. This 3D printer prints nano- and micro-scale 3D metal and polymer structures.
Its technology is derived from Atomic Force Microscopy (AFM). It uses a precision controlled platform (XY axis control accuracy ± 250nm; Z axis control accuracy <5nm) and a closed microchannel (iontip) that can transport nano-scale materials to make a molded 3D or The 2.5D structure, with different iontip solution module nozzles, will be able to be applied to the R & D and verification of biophysics, life sciences, micro-electromechanical, semiconductor and other 3D printing fields, helping to provide solutions for microstructure research. It is expected to lead the development of domestic semiconductor and pharmaceutical biotechnology to a new page.
FluidFM μ3Dprinter is used for nanolithography, rugged surface printing, nano- and micro-scale 3D metal and polymer structure printing.
FluidFM technology combines the superior pressure sensing of microfluidics and atomic force microscopy, and microchannels in the ion probe allow trace liquids to circulate.
The unique combination of microfluidics and atomic force microscopes can create more complex and more pure metallic objects. Optical atomic force feedback mechanism allows instant process control. The smallest diameter of the FluidFM ion probe injection port can be less than 1/500 of the diameter of a human hair. With this injection caliber size, the minimum flow rate can reach several liters per second, which is the detection limit of the current state-of-the-art flow detectors 1 / 1,000,000. FluidFM technology enables the fabrication of micro-nano-scale complex metal objects.
Its technical parameters look even more amazing:
Theoretical printing space (metal): up to 1,000,000 μm3
Forming space (mm): 100 x 70 x 60
Printing speed: up to 100 μm / s
Positioning accuracy: XY ± 250 nm & Z ± 5 nm
Print control: instant
Printing accuracy: nanometer level
Print injection volume: fly upgrade
This unique technology is mainly used for:
3D printing: FluidFM micro-nano 3D printer can directly print micro-nano-scale complex metal objects.
Multi-metal printing: copper, silver, gold, and platinum. Currently, more than 30 metals (nickel, chromium, cadmium, iron, indium, zinc, etc.) are being researched for electrochemical additive manufacturing technology.
Nano-lithography technology: print nano-scale vectors and complex 2D structures. Can be configured with a variety of liquids and nanoparticles, soaring precision, nanometer level.
Surface repair: It can perform high-precision surface repair and transformation, can print with many materials, and has accurate structure.
In addition to this micro-nano 3D printer "FluidFMμ3Dprinter", Beijing U-Smart also introduced the world's first single-cell injection experimental machine "FluidFM BOT" developed by Swiss Cytosurge AG. The device is mainly focused on single cell research, can accurately select cells, and successfully inject drugs, gene codes, etc. into designated cells for observation and analysis.
