  • 12. An overview of additive manufacturing technologies and their evolutions
  • 13. Multijet Modeling or Polijet Modeling  Reduced size of equipment that allow a use desktop type.  Models with high dimensions quality.  Process quickly and silent. Build Material An overview of additive manufacturing technologies and their evolutions
  • 14. Eletron Beam Melting (EBM)  ARCAM EBM machine use a high power electron beam that generates the energy needed for high melting capacity of metal powders.  The vacuum system provides a base pressure of 1×10-5 mbar or better throughout the entire build cycle. An overview of additive manufacturing technologies and their evolutions
  • 15. Electron Beam Melting (EBM) Orthopedic area Aerospace area Low pressure turbine blade in y-titanium Courtesy of Avio S.p.A An overview of additive manufacturing technologies and their evolutions
  • 16. NASA is studying the use of "addictive manufacturing" technology using compound of lunar rocks to build a lunar settlement  Berok Khoshnevis is developing a system called "contour crafting" designed to build 3D structures of large dimensions.  Like all 3D printing, the system builds layer by layer. It consists of a nozzle and spatulas computer controlled. The nozzle deposits a concrete compound, and the paddles smooth surface, layer by layer. Recent project for Aerospace area Rendering courtesy of de Behnaz Farahi e Connor Wingfield.
  • 17. On November 19, 2013 The University of Kentucky and the State University Moorehead along with Kentucky Space, launched KySat-2 into orbit as part of NASA's mission "Elana IV de Wallops " at the launch base of Virginia.  USA CRP with CRP Technology produced using SLS technology pieces in Windform XT 2.0 which are incorporated into solar panels KySat-2; Support camera, lens cover, detachable extensions, clips antennas and battery holders.  Windform XT 2.0 Polyamide-based materials filled with carbon fiber HDT (1.82 Mpa) 173.4 ° C 83.84 Mpa UTS Elastic Modulus 8928.2 MPa. Recent project for Aerospace area
  • 18. Recent project for automotive area
  • 19. Nokia 3D printing community The project Nokia's 3D printing community is offering to customers the ability to create your own skins. Nokia has released files for 3D printing for the Lumia 820. This smartphone with Windows 8 features has an interchangeable cover that users can not only exchange with cover produced by Nokia in different colors as well as printing your custom covers. This development kit contains printing 3D file for 3D printers as well as tutorials and tips on how to create your own custom cover for Lumia 820 files including 3D model, specifications etc..

  • 20. Sarah Silbert post on 08 /03/2013  Earlier this week, a man "unnamed" in the United States had 75% of Its cranium replaced with a plastic prosthesis produced by "addictive manufacturing".   It is the first known surgery of this type.  Oxford Performance Materials: OXPEKK ®-IG was designed to meet the standards of the U.S. FDA and European standards for use and implantable devices for long time periods. Recent project for medical area
  • 21. Livrea 26, the future of boat design uses 3D Printing technology Febbraio 14, 2014 4:29 PM Federico Maselli  Miami, USA on days when the attention of the nautical world's looks Progressive Insurance Miami Boat Show , one of the few Italian exhibitors and Francesco Belvisi, General Manager of YAM-Marine Technology.  In the most important trade fair for boating in the U.S., the Italian manager shows the prototype Livrea 26. Built in Modena in collaboration with industry and Windform CRP Technology, the boat brings inspirations Lancia pantesca typical for the island of Pantelleria. Recent projects for nautical area
  • 22. Analyzing the market we can identify the following topics:  The additive manufacturing technology had evolved in construction speed, in the geometry definition and now is possible use the part.  Several hybrid machines appeared using the concepts of additive manufacturing and traditional subtractive manufacturing like milling.  The maturity of additive manufacturing is confirmed by the appearance of traditional suppliers of milling machines with hybrid construction. Conclusions
  • 23. Speaking about materials we can identify a big developments in applicability:  Whereas metallic materials, advances in the SLS process, the appearance of EBM and use of ultrasonic welding process applied to the additive process LOM can generate parts with very complex geometries and use them with little need for rework, while maintaining the same mechanical characteristics parts produced with traditional process.  The same does not apply to plastic materials due to lack of new usable materials in processes such as SLS and FDM. Conclusions
  • 24. New plastic materials for additive manufacturing:  ULTEM (PEI polyeterimida) ULTEM amorphous thermoplastic resin provides exceptional heat resistance, high strength and stiffness, and broad chemical resistance developed by Stratasys.  Oxford Performance Materials: OXPEKK ®-IG was designed to meet the standards of the U.S. FDA and European standard for use by implantable long time periodes appliances.  Windform 3D printing is a line of materials that after 3D printing can be machined on CNC or conventional procedures if necessary, plans for the geometries with tight tolerances developed by the R & D department of CRP Technology.  During EuroMold, Stratasys announced a new material for the FDM machines high end, Nylon 12 one of the most used materials in industrial applications. Conclusions
  • 25. The market of plastic materials for additive manufacturing:  The market for plastic materials for 3D printing was $ 70.5 million in 2012. According to "Markets and Markets Report" reached U.S. $ 209.6 in 2018. Conclusions
