Additive manufacturing or 3D printing is the process of making a 3 dimensional solid object of virtually any shape of digital model that you wanted to print. 3D Printing is considered as distinct from traditional machining techniques. A 3D Printer performs it printing using digital technology. This technology is used in Jewelry, Footwear, Industrial design, architecture, engineering, construction, automotive, aerospace, information technology, dental, medical industries and many other fields.
At first we discuss that Nanoscribe a spin-off from the Karlsruhe Institute of Technology in Germany has developed a table top 3D Micro printer that can create complicated Micro structures 100 times faster than is possible today with available 3D printer in the market. If any printing took nearly one hour to complete the work, then it takes less than one minute explained by chief scientific officer at Nanoscribe in Germany. Now 3D printing of Toys, iPhone covers, and Jewelry continues to grab headlines much of 3D printing’s impact could be at a much smaller scale at present. At present Micrometer scale printing has shown promise for making medical and electronic devices quickly and sharply.
The chief scientific officer said that it should be possible to speed up his company’s Micro printing technology even more in the coming future. The company Nanoscribe plans to start selling its machine in the second half of this year in 2013. To making Shape Two Scanning Electron microscope images show a printed cell scaffold and an array of Micro needles in it.
Doing printing microstructures with features a few hundred nanometers in size could be useful for making Heart Stents, Micro needles for painless shots, gecko adhesives, parts for Micro fluidics chips and scaffolds for growing Cells and Tissue. More important application could be in the electronics industry is where patterning nanoscale features on chips currently involves slow and very much expensive techniques at present. This 3D printing would quickly and cheaply yield polymer templates that could be used to make metallic structures at last. Another use of 3D microprinting has been used only in research laboratories because it is pretty slow in processing. By many research labs around the world use Nanoscribe’s first-generation printer up to now and the new faster machine will also find commercial use in coming future. Chief Executive scientist said that numerous medical, life sciences, and nano technology companies are interested in the new machine made by the company. Thinking positive that with the faster throughput we get with this new tool and it might have an industrial breakthrough very soon he added.
Now this technology is behind the most 3D Micro printers is called two photon polymerization and It involves focusing Tiny, Ultrashort pulses from a near-infrared laser on a light sensitive material. And the material polymerizes and solidifies at the focused on the spots as well. In this process laser beam moves in three dimensions to it creates a 3D object. At present printers, including Nanoscribe’s present system, keep the laser beam fixed and move the light on sensitive material along three axes using mechanical stages which slows down printing according operations to speed up the process, Nanoscribe’s new tool uses a tiny moving mirror to reflect the laser beam at different angles between the process. Further Executive says that to generating multiple light beams with a microlens array could make the process even faster that required in it.
Here another smallest features that can be created using the Nanoscribe printer measure about 30 nanometers says professor of materials science at the California Institute of Technology. There is no doubt about that it is very challenging to do and the Nanoscribe tool excels at it. I don’t think there is another company out there that is capable of such precision at present and the research team uses the first-generation Nanoscribe printer to create and study materials that could be used for catalysts and to make Strong, Lightweight structures, but it acknowledges that its slowness is a drawback but it can be make faster in coming future.
