3D PRINTING What is 3D Printing ?  3D Printing refers to a relatively new class of manufacturing methods which quickly produce physical prototypes from 3D CAD data  Also known as rapid prototyping, layered manufacturing or additive manufacturing)  3D Printing Processes use layer by layer addition  3D Printing does not require any mold as a precursor to manufacture  Multiple parts can be produced in one cycle  3D Printing has been used successfully to make parts of various sizes  Geometric complexity is not a limitation in 3D Printing Rapid Prototyping  Fused Deposition Modeling (FDM)  Stereolithography (SLA)  Selective Laser Sintering (SLS)  Powder Jetting  Laminated Object Manufacturing (LOM)  Rapid Prototyping Technologies  3D Inkjet Printing  Laser Engineered Net Shaping  Selective Laser Melting  Electron Beam Melting Applications of 3D Printing  Touch and Feel  Form, Fit and Function  Wind Tunnel Testing  Validation of Invention  Patterns for Casting  Molds for Casting  Patterns for Casting  Jewelry Design  Direct Tooling  Reverse Engineering  3D Printing can make parts in Biocompatible materials  Prototypes for Medical Applications  Mass Customization Materials Options for 3D Printing  Metallic materials  Plain Carbon Steel,  Tool Steel,
