3D printing involves using digital files and additive processes to create physical objects by laying down successive layers of material. It starts with a 3D digital design which is then sliced into layers and used by the 3D printer to extrude or bind material to build the final object layer by layer. There are several technologies used in 3D printing including selective laser sintering (SLS) and fused deposition modeling (FDM). 3D printing has applications in industries like healthcare for prosthetics, aerospace for aircraft parts, and automotive for prototypes. As technologies advance, 3D printing is expected to significantly impact manufacturing.

- 2. What is 3D printing?
- 3. What is 3D printing? • Making three dimensional solid objects from a digital file. • Created by laying down successive layers of material until the entire object is created.
- 4. How does 3D printing work?
- 5. How does 3D printing work? • Starts with making a virtual design of the object you want to create. • Use CAD file using a 3D Modeling program • Use of a 3D scanner • 3D scanner makes a 3D digital copy of an object.
- 6. How does 3D printing work? • Microsoft and Google enabled their hardware to perform 3d scanning, a great example is Microsoft’s Kinect (Using Kinect Fusion) • A clear sign that future hand-held devices like smartphones will have integrated 3d scanners.
- 7. How does 3D printing work? • 3D modeling software “slices” the final model into hundreds or thousands of horizontal layers. • When the sliced file is uploaded in a 3D printer, the object can be created layer by layer. • The 3D printer reads every slice and creates the object, blending each layer with hardly any visible sign of the layers, with as a result the three dimensional object.
- 9. Processes and Technologies • Not all 3D printers use the same technology. 1) Vat Photopolymerisation 2) Material Jetting 3) Binder Jetting 4) Material Extrusion 5) Powder Bed Fusion 6) Sheet Lamination 7) Directed Energy Deposition
- 10. Processes and Technologies Most Common Technologies • Selective Laser Sintering (SLS) • Fused Deposition Modeling (FDM)
- 11. Selective Laser Sintering (SLS)
- 12. Selective Laser Sintering (SLS) • The ability of SLS to produce several pieces at one time. • Good choice for Direct Digital Manufacturing (DDM) of products requiring strength and heat resistance.

- 20. Examples & Applications Examples – Reconstructing fossils in Paleontology – Replicating ancient artifacts in Archaeology – Reconstructing bones and body parts in Forensic Pathology – Reconstructing heavily damaged evidence acquired from crime scene investigations
- 21. Examples & Applications Applications – Rapid prototyping – Architectural scale models – Healthcare (3D Printed Prosthetics) – Entertainment
- 23. 3D Printing Industry Medical industry – Improved quality of care through 3D printed implants and prosthetics never before seen. – Tissue engineering applications where organs and body parts are built using inkjet techniques. – Layers of living cells are deposited onto a gel medium and slowly built up to form three dimensional structures
- 24. Medical Industry
- 25. 3D Printing Industry Aerospace & Aviation industries – For a large part, be derived from the developments in the metal additive manufacturing sector. – NASA for instance prints combustion chamber liners using Selective Laser Melting.
- 26. Aerospace & Aviation industries
- 27. 3D Printing Industry Automotive Industry – Simple concept models for fit and finish checks and design verification – Functional parts that are used in test vehicles, engines, and platforms.
- 30. Industrial Printing Rapid Prototyping – Manufacturers use 3D printers in their design process to create prototypes for traditional manufacturing and research purposes. – For example, Nike uses 3D printers to create multi-colored prototypes of shoes. They used to spend thousands of dollars on a prototype and wait weeks for it. – Now, the cost is only in the hundreds of dollars, and changes can be made instantly on the computer and the prototype reprinted on the same day.
- 31. Industrial Printing Rapid Manufacturing – Manufacturers use 3D printers for short run custom manufacturing. – In this way of manufacturing the printed objects are not prototypes but the actual end user product.
- 33. Personal Printing • Mainly for hobbyists and enthusiasts. • Rapid development within this new market printers are getting cheaper and cheaper. • Prices typically in the range of $250 – $2,500.
- 34. Future
- 35. Future • 3D Printing technological development will change the nature of commerce. • End users will be able to do much of their own manufacturing rather than buy products from other people and corporations. • 3D printers capable of outputting in color and multiple materials already exist. • Will effects on energy use, waste reduction, customization, product availability, medicine, art, construction and sciences. • 3D printing will change the manufacturing world.
