3-D Printing

  1. 1. “If A Picture Is Worth A Thousand Words… A Prototype Is Worth A Thousand Pictures”
  2. 2. What is 3D Printing ? 3D printing or additive manufacturing is a process of making three dimensional solid objects from a digital file. The creation of a 3D printed object is achieved using additive processes. In an additive process an object is created by laying down successive layers of material until the entire object is created.
  3. 3. 1984 - 86 Charles Hull invents 3D printing and coins the term ―Stereo Lithography‖ 1992 First 3D printer built by 3D Systems 1999 First application of 3D printing in the medical field - creating the human bladder History
  4. 4. How it works ? The 3D printing technique basically has the following steps :  Forming 3D printable model.  Printing the model.  Finishing of the model
  5. 5. FORMING 3D PRINTABLE MODEL : A printable model can be formed either by using a computer Aided Designing software package or using a 3D scanner.  A 3D scanner is an industrial robot which scans a particular object and records it’s dimensions and provides input to the printer.
  6. 6. PRINTING THE MODEL :  Depending on the data provided the printer lays down several layers of liquid, paper, polymer, plastic or other material depending on the material required.  Printer resolution describes layer thickness and X-Y resolution in micrometers.  3D printers give designers and concept development teams the ability to produce parts and concept models using a desktop size printer.
  7. 7. FINISHING : Though the printer-produced resolution is sufficient for many applications, slightly oversized version of the desired object is removed with a higher-resolution subtractive process and can achieve greater precision.
  8. 8. 3D Printing Medical Food Games & Entertainment Do It YourselfPop-Culture Defense & Space Fashion & Retail Applications :
  9. 9. Medical : 3-D Bioprinting will allow us for the printing of cells placed in predetermined patterns to replicate human tissues, organs and blood vessels. 3D printers are also used for organ transplantation using the cells of the patient’s own body. Other body parts like ears, bones, heart valve, prosthetic parts can be made using 3D printers.
  10. 10. Food Industry : Edible object are created by syringes injected with edible food. 3D printing food can save both time and energy when it comes to experimenting. Even a trained pastry chef cannot achieve the perfection that 3D printing can
  11. 11. Manufacturing : Produce 3D parts and assemblies made from various materials. Reduces the need for tooling machining, and handcrafting prototypes. More efficient designs. Reduces the need to maintain an inventory.
  12. 12. Cost of 3-D Printers :
  13. 13. Advantages : Rapid Prototyping : Gives designers the ability to quickly turn concepts into 3D model or prototype. Clean Process : Wastage of material is negligible. Complex shape can be produced. Easy To Use No skilled person needed.
  14. 14. Disadvantages : 3-D printers are still very expensive. Misuse of technology. Although 3-D printers have the potential of creating jobs and opportunities, they might also put certain jobs at risk.
