3D metal Printer Head

3D metal Printer Head

Recently, researchers at Harvard University have developed an innovative anti-fouling materials, it can significantly reduce the corrosion of iron and steel, and scaling. It can be said that this finding is a boon for 3D printing enthusiasts, because it is equipped with special steel materials can be used as a 3D printer nozzles, which can greatly improve the life and performance.

It is understood that this part of the research team from Harvard University, John a. Paulson College of engineering and applied science. Researchers used rough, Nano-oxides in the surface of the porous manufacture a coating, you can make the alloy is stronger, safer and more durable. The coating was said to be by far the most durable stain resistant and corrosion-resistant materials can be effectively excluded any kind of liquid.

Tico social thought, the material durability and life expectancy for the 3D printer nozzle may have great significance. It is well known that 3D steel parts are equally affected by corrosion and scaling. This is a special daweinita, especially when the user attempts to 3D print highly visco666(1)us material. The viscous resistance of the wires inside the print nozzles are often required as small as possible, in order to ensure its effective and uniform extrusion.

Nozzles and scaling for 3D bio-print technology is a taboo, pollution because it is very easy to print the object. The study’s co-author, SLIPS and technology company co-founder and Vice President of technology Philseok Kim does not believe that this pollution will become a problem in the new material. “Because our research shows that this material can successfully repel bacteria and blood. “Kim said.

Of course, this surface coat in addition to 3D printing in other applications is very wide. Because as a low-cost way of common metals, steel in many fields, including construction, medical and transportation, there is a great deal of application requirements.133423O12-0

Research team principal investigator Professor Joanna Aizenberg in developing free, anti-fouling materials with outstanding achievements. Since 2011 develop a smooth liquid injected into porous surfaces (SLIPS), Aizenberg have proved the many uses of this material. “Our sliding steel than any prior to the anti-fouling materials are more durable. “She explained. “Up to now, the two concepts-mechanical durability and anti-fouling – into one subject. We need surface texture and stain-resistant multiple holes, but rough nanostructured coatings are inherently weaker than that of most of their analogues. The study shows that careful surface works can design a material, the material can realize the function of multiple, even contradictory, without degradation of performance. ”
