On 4th September 2013, presentation of state-of-the-art 3D print technologies took place at the headquarters of EOS GmbH Electro Optical Systems in Krailling near Munich. The presentation was attended by representatives of MBtech Bohemia, EvoBus Bohemia, University of West Bohemia in Pilsen, NTC facility and Blue Projects Agency. EOS supplies technologies for the 3D printing of metallic and plastic structures.
This technology is used when a product needs to be very quickly obtained from a data model, featuring characteristics equivalent to a product manufactured in a conventional way. The basic principle of 3D print in all EOS machines is laser sintering of thin layers of a powder which is gradually and globally distributed in multiple thin layers. After defined parts of each layer gradually fuse together, the resulting product is simply taken out of the box full of unsintered powder. You can picture the gradual sintering of the final part as melting of the flat layers of the parts, which are formed when a part is cut into slices. A complete part is gradually made from these slices of sintered material. It is possible to obtain parts which have the same technical characteristics as steel, stainless steel, chrome cobalt, nickel, as well as PET, polyurethane and other common materials. In addition to other novelties, EOS is preparing 3D printing of precious metals and extension of work space.
