3D Printing

  1. 1. Imagine a world where you can make anything you want, just by pressing the “PRINT” button..!! Savvy…eh?!
  2. 2. By Bijita Sen Netaji Subhash Engineering College
  3. 3. WHAT IS 3D PRINTING? • 3d printing is the means of creating three dimensional solid object from a digital file by adding materials layer by layer. (each of this layer can be seen as a thinly sliced horizontal cross section of the eventual object)
  4. 4. This is how it basically works
  5. 5. Why is it called “Printing”? • If you look closely (with a microscope) at a page of text from your home printer, you’ll see the letters don’t just stain the paper, they’re actually sitting slightly on top of the surface of the page. • In theory, if you printed over that same page a few thousand times, eventually the ink would build up enough layers on top of each other to create a solid 3D model of each letter. That idea of building a physical form out of tiny layers is how the first 3D printers worked.
  6. 6. What kind of “ink” does it use? • Where an inkjet printer sprays liquid ink and a laser printer uses solid powder, a 3D printer uses neither: you can't build a 3D model by piling up colored water or black dust! What you can model with is- plastic! 3D printers use thermoplastics (plastics that melt when you heat them and turn solid when you cool them back down), and typically one called ABS (acrylonitrile butadiene styrene)
  7. 7. Technically, the methods are… Selective Laser Sintering • This technology uses a high power laser to fuse small particles of plastic, metal, ceramic or glass powders into a mass that has the desired three dimensional shape. Fused Deposition Modeling • The FDM technology works using a plastic filament or metal wire which supplies material to an extrusion nozzle which can turn the flow on and off. The nozzle is heated to melt the material and can be moved in both horizontal and vertical directions by a numerically controlled mechanism, directly controlled by a computer. The object is produced by extruding melted material to form layers as the material hardens immediately after extrusion from the nozzle.
  8. 8. Some of the 3d Printer models
  9. 9. How can it be used? • From a pin to an airplane ; from a customized jewelry earring to a fully functional human ear-name anything which comes in mind- we can get it printed out of a 3d printer. Let us see some examples where 3d printing has come to help and how: Manufacturing Industry-Automobile, Aircraft and even spacecraft-all have started using 3d printed parts as they can be more intricate and customised and also time efficient in production.  20,000 parts are now being used for the Boeing aircrafts and they even want to patent them!  GE 3d printed a jet engine very recently which runs at 33,000 rpm.  NASA is recently using full scale 3d printed copper rocket parts.
  10. 10. Let us have a look at few of them…
  11. 11. And the list goes on.. • Construction & Architecture • Firearms • Research Labs • Computers & Robots • Creative Designing & Art • Environmental use
  12. 12. No points for guessing how these are made..!!
  13. 13. Welcome to the age of BioPrinting where the machines which we have built ,are building bits and pieces of US..!!
  14. 14. Some of them are… • Liver cells,kidney cells and bladder cells have been 3d printed and have shown signs of thriving well. Even beating heart cells have also been developed which are very promising. • Imagine if you could take living cells, load them into a printer, and squirt out a 3D tissue that could develop into a kidney or a heart. Scientists are one step closer to that reality, now that they have developed the first printer for embryonic human stem cells.
  15. 15. And others… • Now we will need blood vessels- which can also be printed just by adding sugar and water!! Others include: • Bones & Cartilage • Prosthetics and implants • Bionic ear • Heart valves • Skin graft…..and what not!!
  16. 16. Let’s see how they look…
  17. 17. Blind mother “sees” her “unborn” child thanks to 3d printed ultrasound..!!
  18. 18. Guess who this is with his life size 3d printed model..!!
  19. 19. Is it THE NEXT BIG THING? • Well, the answer is certainly YES.! • Like all emerging technology which means like mobile phones and computers, most people will be skeptical about needing one until everyone has got one and then we‘ll wonder..how we ever managed without them..!!
