Transcript

  • 1. 3D PRINTING A Technology towards revolution BY: Saumya Ranjan Behura
  • 2. Topics • What is 3D printing? • Additive Process • General Principles • 3D Printing Technology • Work Flow • Why 3D Printing? • Applications • Videos  • Conclusions 2
  • 3. What is 3d printing? • The technology used for printing physical 3d objects from digital out is called 3d printing. • I t was first developed by Charls Haul in 1984. • It is also called RAPID PROTOTYPES. • In 1993, Massachusetts Institute of Technology (MIT) patented another technology, named "3 Dimensional Printing techniques", which is similar to the inkjet technology used in 2D Printers.
  • 4. Additive Manufacturing: The term additive manufacturing refers to technologies that create objects through a sequential layering process. Objects that are manufactured additively can be used anywhere throughout the product life cycle,
  • 5. General Principles Modeling Printing Finishing
  • 6. General Principles Modeling: Additive manufacturing takes virtual blueprints from computer aided design (CAD) or animation modeling software and "slices" them into digital cross-sections for the machine to successively use as a guideline for printing.
  • 7. General Principles Printing: To perform a print, the machine reads the design and lays down successive layers of liquid, powder, or sheet material to build the model from a series of cross sections. These layers, which correspond to the virtual cross sections from the CAD model, are joined together or automatically fused to create the final shape. The primary advantage of this technique is its ability to create almost any shape or geometric feature.
  • 8. General Principles: Finishing : Though the printer-produced resolution is sufficient for many applications, printing a slightly oversized version of the desired object in standard resolution, and then removing material with a higher-resolution subtractive process can achieve a higher-resolution
  • 9. 3D PRINTING TECHNOLOGY: Stereolithography Selective laser sintering (SLS) Multi-jet modeling (MJM) Inkjet 3D printing
  • 10. Stereolithography • Stereolithography is a process for creating threedimensional objects using a computer-controlled laser to build the required structure, layer by layer. It does this by using a resin known as liquid photopolymer that hardens when in contact with the air.
  • 11. Selective laser sintering (SLS) • This builds objects by using a laser to selectively fuse together successive layers of a cocktail of powdered wax, ceramic, metal, nylon or one of a range of other materials.
  • 12. Multi-jet modeling (MJM) • This again builds up objects from successive layers of powder, with an inkjet-like print head used to spray on a binder solution that glues only the required granules together. The V-Flash printer, manufactured by Canon, is low-cost 3D printer. It’s known to build layers with a lightcurable film. Unlike other printers, the VFlash builds its parts from the top down.
  • 13. Inkjet 3D printing • It creates the model one layer at a time by spreading a layer of powder (plaster, or resins) and inkjet printing binder in the cross-section of the part. It is the most widely used 3-D Printing technology these days and the reasons beyond that are stated below. • This technology is the only one that • Allows for the printing of full color prototypes. • Unlike stereo lithography, inkjet 3D printing is optimized for speed, low cost, and ease-of-use. • No toxic chemicals like those used in stereo lithography are required. • Minimal post printing finish work is needed; one needs only to use the printer itself to blow off surrounding powder after the printing process. • Allows overhangs and excess powder can be easily removed with an air blower.
  • 14. Inkjet 3D printing
  • 15. WORK FLOW :
  • 16. CAD Preparation (Pre-Process):
  • 17. 3D Printing:
  • 18. Cleaning 3D Printouts (Post-Process):
  • 19. Powder Removal:
  • 20. Heating
  • 21. Finishing Touches
  • 22. WHY 3D PRINTING? Increase Innovation Improve Communication Speed Time to Market Reduce Development Costs Win Business
  • 23. APLLICATION OF 3D PRINTING : Design Prototypes: •3-Dimensional Printing concept model, functional prototypes and presentation models for evaluating and refining design, including Finite Element Analysis (FEA) results and packaging. •Size: 3.5 x 2 x 0.7 inches •(9 x 5 x 2 cm) •Printing Time: 0.5 hours
  • 24. APLLICATION OF 3D PRINTING : Education: •Engage students by bringing digital concepts into the real world, • turning their ideas into real-life 3D color models that they can actually hold in •Size: 8 x 5 x 2.5 inches •(20 x 13 x 6 cm) Printing Time: 3 hours
  • 25. APLLICATION OF 3D PRINTING : Healthcare: •Rapidly produce 3D models to reduce operating time, enhance patient and physician communications, and improve patient outcomes. •Size: 9.8 x 7.9 x 3.9 inches 25 x 20 x 10 cm) •Printing Time: 5.5 hours
  • 26. APLLICATION OF 3D PRINTING : Reduce material wastage More local manufacturing Increased customisation Digital storage & transportation Open design & MANYMORE
  • 27. VIDEOS:
  • 28. CONCLUSION: Nothing communicates ideas faster than a threedimensional part or model. With a 3D printer you can bring CAD files and design ideas to life – right from your desktop. Test form, fit and function – and as many design variations as you like – with functional parts.
