3D Printing

  1. 1. Instructed on: 17-Feb-2012 | Session: #05 By: Mohanad Yehia Topic Code: TCW-04-2012 All Copy Rights Saved to the 7th Students’ Conference on Communication and Information Based in the Faculty of Computers and Information Cairo University – Egypt 2011/2012 www.scci-cu.com
  2. 2.  What is 3D printing? 3D printing process. 3D printing techniques. 3D printing applications. Advantages. Against.
  3. 3. is a form of additive manufacturing technologywhere a three dimensional object is created bylaying down successive layers of material. It is alsoknown as rapid prototyping.
  4. 4. startLayer of powder deposit automaticallyPrint head applies resin to powder layer Powder layer dries almost immediately Add another Yes layer? No Remove completed model Finish
  5. 5. Spread a layer of powder Print cross section Print a layer of powder
  6. 6.  Stereo lithography (SLA). Fused deposition modeling (FDM). Selective laser sintering (SLS).
  7. 7.  A perforated platform is positioned below the surface of a liquid photo curable polymer. A UV laser beam traces the first slice on the surface of this liquid, causing a very thin layer of photopolymer to harden. Another slice is then created, and so on.
  8. 8. Here a hot thermoplastic is extruded from atemperature-controlled print head toproduce fairly robust objects to a high degreeof accuracy.
  9. 9. This builds objects by using a laser toselectively fuse together successive layers ofa cocktail of powdered wax, ceramic, metal,nylon or one of a range of other materials.
  10. 10.  Product formation (prototyping). Metal casting. Geospatial designs. The use of 3D scanning technologies allows the replication of real objects. Architects need to create mockups of their designs.
  11. 11.  3D printing allows artists to create objects that would be incredibly difficult, costly, or time intensive using traditional processes. In Medical Field, Surgeons are using 3d printing machines to print body parts for reference before complex surgeries. Looking further in the future, research is underway as scientists are working on creating replacement organs.

  21. 21.  Increased part complexity. Digital design and manufacturing. Relatively low cost and time. Instant production on a global scale. Waste reduction (Green technology).
  22. 22.  High cost for domestic use. 3D printing technology may have implications for artistic copyright, design right and trade marks. Bad option for common designs.
