Since a long time Nano – technology has been confined to the range of those things that will probably happen in the future. Now there is so much, NanoTech material around us that it is almost a common element. The same is now happening for Commercial Nanofabrication. The ability to 3D print Nano grade Photonic Wire Bonds (PWB) will allow computer scientists to overcome communication bottlenecks in data centers and high performance computers. In biotechnology Nano-Scaffolds are making it easier than ever to grow all types of living cells.
Nano – fabrication will have applications in the development of mechanical meta – materials and of new Nano surfaces that will, for example, replicate a Gecko’s setae, giving any one and any object Spider-man like climbing (or clinging) abilities. Another application is in filtration systems: with Nanoscribe’s machine it is possible to create Nano – fluidic filters inside channels that are only a micrometer wide.
How is Nano fabrication done?
The technology used to 3D print at a Nano scale, is called Two Photon Polymerization or Two Photo Lithography. It is very similar to regular stereo lithography, except that it uses femtosecond laser pulses (a femtosecond is 10 to the -15th seconds or 0.000000000000001 seconds) to cure the polymers at the Nano – scopic level).
Nanoscribe has developed a range of software that, just like in any desktop 3D printer, can make all the difference both in quality and accessibility.
Nanowrite is an easy to use GUI, while the Nanoslicer software transforms the “*.stl” files into the Photonic Professional GT native data format: “*.gwl”. Through the DeScribe software users can edit the GWL files, check them for printability and even monitor the writing process by means of an SEM (scanning electron microscope) connected optical camera.
Nano – printing will allow for the creation of Nano – circuits and Meta-materials and also printing Organic tissue at the Nano – scale. 3D printing’s utility in such a diverse set of fields proves that it will indeed be a ubiquitous technology in the coming years.
