  3. 3. Overview of 3D Printing “3D printing” or “Additive Manufacturing” takes digital input in the form of Computer Aided Design (CAD) model and creates solid, three dimensional parts through an additive, layer by layer process.
  4. 4. Types of Manufacturing Additive Manufacturing Subtractive Manufacturing Additive Manufacturing could reduce energy use by 50% and reduces material costs by up to 96% compared to traditional manufacturing.
  5. 5. General Principles 1.Modelling:It takes virtual blueprints from modeling software and “slices” them into digital cross-sections for the machine to successively use as a guideline for printing. 2.Printing:To perform a print, the machine reads the design from an .stl file and lays down successive layers of liquid, powder, paper or sheet material to build the model from a series of cross section. 3.Finishing
  6. 6. How Does It Work? A person creates a 3D image of an item using a 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?
  7. 7. Methods of 3D Printing 1.Selective Laser Sintering(SLS) 2.Stereolithography 3.Fused Deposition Modeling(FDM) Stereolithography FDM
  8. 8. Selective Laser Sintering It is an additive manufacturing technique that uses a high power laser( for eg. CO2 laser) to fuse small particles of plastic, metal, ceramic or glass powders into a mass that has a desired 3D shape.
  9. 9. Stereolithography It is an additive manufacturing process that works by focusing an ultraviolet (UV) laser on to a vat of photopolymer resin.
  10. 10. Fused deposition modeling It build parts layer-by-layer from the bottom up by heating and extruding thermoplastic filament. Used for modelling, prototyping and production applications.
  11. 11. FDM
  12. 12. 3D Printing Materials 1.Plastic FilamentAcrylonitrile Butadiene Styrene (ABS) PLA Polylactic acid or polylactide (PLA, Poly) Flexible Plastic (TPE) Nylon
  13. 13. 2.Metals Brass, Bronze, Platinum, Silver and Gold Steel Aluminum
  14. 14. Applications 1.Concept Modeling :This lets small design and engineering firms extend their reach by testing out more ideas . 2.Functional Prototyping: It helps in creating amazingly realistic prototypes with the look and feel of a real product. Example: Lamborghini, while developing its new flagship model Aventador has made extensive use of 3D printing technology to build a functional prototype of the car.
  15. 15. 3.Manufacturing Tools: Quick, low-volume tooling and custom fixtures give manufacturers the flexibility to embrace more opportunities. 4.End-User Parts 5.Food 6.Fashion & Retail
  16. 16. 7.Medical: Artificial Arms for Disabled Secrets of the HeartMedical Equipments Bioprinting Tissues and organs
  17. 17. Future Scope 1.Complex Engine parts. 2.On demand parts in Space. 3. Aircraft Wings. 4. 3D Printing as a Service(3DPaaS)
  18. 18. 5.3D-printed Lunar Base 6.Design your own clothes 7.Print your home
  19. 19. Advantages and Disadvantages Advantages: Ability to customize products Rapid production of prototypes. Low cost of production. No storage cost Quick availability of organs.
  20. 20. Disadvantages: Intellectual property issues Unchecked production of dangerous items Limitations of size Limitations of raw material Cost of printers
  21. 21. 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.
