  • 2. Printing Printing is a process for reproducing text and images, typically with ink on paper using a print press.
  • 3. •GUTTENBERG’S PRINTING PRESS. •INVENTED IN 15TH CENTURY •USED MOULDS MADE OF BRASS HISTORY OF PRINTING
  • 4. Invention of first printing machine  FIRST PRINTING MACHINE WAS INVENTED BY JOHANNESGENSFLEISH IN 1803.  THIS SUPERSEDED THE COST AND SLOW PRODUCTION.
  • 5. HISTROY OF 3D Printing 3D printing was invented in the year 1984 by Charles Hull with the advancements in printing methods after the invention of inkjet printers in the year 1976. Charles Hull is the co-founder, executive vice president and chief technology officer of 3D systems.
  • 6. FIRST 3D PRINTER
  • 7. Subtractive Manufacturing • Creates a product by removing sections from a block of material. • Generates waste through the excess material that is removed. • Limited design capabilities.
  • 8. Computerized Numerical Control (CNC) Machining • A method of Subtractive Manufacturing that removes sections from a block of material by cutting or drilling the excess material away.
  • 9. 3D Printing • A method of Additive Manufacturing that adds material to an object layer by layer to create the final product.
  • 10. Technique
  • 11. A person creates a 3D image of an item using a computer- aided design (CAD) software program. The CAD information is sent to the printer. The printer forms the item by depositing the material in layers—starting from the bottom layer—onto a platform. In some cases light or lasers are used to harden the material. How Does It Work ?
  • 12. Different methods Selective laser sintering (SLS) Stereo lithography Fused deposition modeling (FDM) Laminated object manufacturing
  • 13. SLS method Selective laser sintering (SLS) is an additive manufacturing technique that uses a high power laser (for example, a carbon dioxide laser) to fuse small particles of plastic, metal (direct metal laser sintering),ceramic or glass powders into a mass that has a desired 3-dimensional shape
  • 14. STEREOLITHOGRAPHY Stereo lithography is an additive manufacturing process using a vat of liquid UV-curable photopolymer ”resin” and a UV laser to build parts a layer at a time.
  • 15. STEREOLITHOGRAPHY (contd). • CAD (Computer Assisted Design) Programs help users create STL Files for the 3D Printers to read. • STL (STereoLithography) file format – a file format which uses many little triangles to make a 3 dimensional plot of the objects intended surface.
  • 16. FDM Fused deposition modeling (FDM) is an additive manufacturing technology commonly used for modeling, prototyping, and production applications The commonalty used raw material is ABS- M30 which is a kind of plastic
  • 17. Laminated object manufacturing Laminated object manufacturing (LOM) is a rapid prototyping system developed by Helisys Inc. In it, layers of adhesive-coated paper, plastic or metal laminates are successively glued together and cut to shape with a knife or laser cutter.
  • 18. RAW MATERIAL USED FOR 3D PRINTING  ABS-M30 :The ABS-M30 plastic formulation is the plastic  ABS-ESD7 : ABS-ESD7 is the Stratasys electrostatic dissipative material  PC-ABS  ABS-M30i  ABSi  PC  ULTEM 9085  FDM Nylon 12  ETC… Material Key Characteristics ABS-M30, ABSplus Versatile, tough ABS-ESD7 Electrostatic discharge resistant ABS-M30i Biocompatible ABS-M30i Translucent PC Strong (tension) PC-ABS Strong (impact) PC-ISO Mechanically well-rounded. FST certification ULTEM 9085 Resistant (thermal/chemical) Nylon 12 Strong (high fatigue resistance)
  • 19. USES OF 3D PRINTING 3D Printing Medical Food Games & Entertainment Do It YourselfPop-Culture Defense & Space Fashion & Retail
  • 20. Functional Prototyping Use: Functional prototyping helps in creating amazingly realistic prototypes with the look and feel of a real product. Example: Lamborghini, while developing its new flagship model Aventador in 2011, made extensive use of 3D printing technology to build a functional prototype of the car.
  • 21. Concept Modeling Use: Concept modeling lets small design and engineering firms extend their reach by testing out more ideas and developing only the right projects. For large companies, concept modeling within departments — or even in individual cubicles — is a way to hone ideas before presenting them to superiors. Example: California-based 3D Reprographics makes architectural models for its clients. They found 3D printing to be a great fit for making a strong accurate presentation model.
  • 22. End Use Parts Use: 3D printing is capable of building the most durable, stable, and repeatable parts in the industry, whose accuracy can be compared with injection molding. Example: Kelly Manufacturing Company (KMC), the world’s largest manufacturer of general aviation instruments, makes extensive use of 3D printing by producing prototypes of critical components for an aircraft quickly; the process would otherwise take an estimated 3-4 weeks.
  • 23. Fashionable Plaster This 3D-printed cast to help repair broken bones may be the future of medical orthopedic casts. 3D-printed casts also bring out the positive potential of this emerging technology.
  • 24. Fashion, Retail & Home decorator Creative home decorators….
  • 25. Applications of 3D Printing • Prototyping • Modeling • Custom parts • Design • Research
  • 26. SUCCESS stories 3D printed Jaw Artificial Arms for Disabled
  • 27. Challenges Facing 3D Printing • Intellectual property rights of the 3D Printer users. • Nearly anything can be printed by 3D Printers and this is a troubling prospect if criminals use 3D Printers to create illegal products.
  • 28. In Conclusion • 3D printing is an expanding technology which may soon start an industry in which everyone has the possibility of being a manufacturer. • 3D printing has a lot of possible benefits to society, although the products created must be regulated.
