are being explored 3 d printing a wider range of applications, including manufacturing, medical equipment, fashion and even food. However, one of the most effective form of 3 d printing has a big disadvantage: it can only print grey or black object. Now, the researchers of this approach have been adjusted, so it can print out all the colors of the rainbow. They published on the ACS journal Nano Letters their results.
selective laser sintering ( SLS） Printers use laser to heat a particular area of the powder materials, usually nylon or polyamide, this will melt or powder sintering to form solid. Then, selectively to join the new powder material layer, the printer until get the 3 d structure. In order to reduce the process of energy demand, the researchers in the polymer powder added a compound called photosensitizer. These materials, such as carbon nanotubes, carbon black and graphene, much bigger than the strength of the polymer absorb light, and transfer of heat to them, so that they can use cheaper, more low power laser. However, based on carbon photosensitizer can only produce grey or black print objects. Gerasimos Konstantatos, Romain Quidant and they in photon science institute ( IFCO) Colleagues wanted to find a can be implemented by the method of SLS photosensitizer for the color printing.
the researchers designed a gold nanorods, so strongly absorb energy in the near infrared spectrum, at the same time, it is almost transparent to visible light. They give their Shanghai juji silicon dioxide, then mix with polyamide powder print 3 d objects. They found that, compared with the industry standard for carbon black, gold nanorods in converts light from a laser to heat energy is much better. In addition, the new photosensitizer can produce white color more, when mixed with the dye - — 3 - can have a colorful D object. It is important that these materials cost-effective for mass production. Researchers have already submitted an application for a patent for several new technologies related.
