- 2. Title • “3D printing” or “Additive Manufacturing” takes digital input in the form of Computer Aided Design (CAD) model and creates solid, three dimensional parts through an additive, layer by layer process.
- 3. How does it work A person creates a 3D image of an item using a computer- aided design (CAD) software program. The CAD information is sent to the printer. The printer forms the item by depositing the material in layers—starting from the bottom layer—onto a platform. In some cases light or lasers are used to harden the material.

- 6. 2000 Miniature human kidney created through 3D printing 2006 The Selective Laser Sintering machine – printing multiple materials & fields 2009 First usable prosthetic leg – this opens the door for customized products using 3D printing 2011 3D printers start offering 14k gold as printable material
- 7. Projected growth It is predicted that the 3D printing industry is set to grow 300% in the next 7 years! (Source: http://on3dprinting.com/2012/08/06/infographic-how-3d-printing-works-industry-growth-stocks-and-more/ )
- 9. Concept Modeling Use: Concept modeling lets small design and engineering firms extend their reach by testing out more ideas and developing only the right projects. For large companies, concept modeling within departments — or even in individual cubicles — is a way to hone ideas before presenting them to superiors. Example: California-based 3D Reprographics makes architectural models for its clients. They found 3D printing to be a great fit for making a strong accurate presentation model.
- 10. unctional prototyping Use: Functional prototyping helps in creating amazingly realistic prototypes with the look and feel of a real product. Example: Lamborghini, while developing its new flagship model Aventador in 2011, made extensive use of 3D printing technology to build a functional prototype of the car.
- 11. Manufacturing tools Use: Quick, low-volume tooling and custom fixtures give manufacturers the flexibility to embrace more opportunities. Example: Xerox introduced a low-volume printer to serve a specialized market. 3D printing offered quick solutions with 350 components printed and generated within 1 hour for testing of the new machine.
- 12. d Use Parts Use: 3D printing is capable of building the most durable, stable, and repeatable parts in the industry, whose accuracy can be compared with injection molding. Example: Kelly Manufacturing Company (KMC), the world’s largest manufacturer of general aviation instruments, makes extensive use of 3D printing by producing prototypes of critical components for an aircraft quickly; the process would otherwise take an estimated 3-4 weeks.
- 13. Finishing Use: Sealing, polishing and painting expand the possibilities of what a 3D printer is capable of. Example: Product Development Solutions (PDS) specializes in supplying components to a wide range of industries including medical and aerospace. It makes extensive use of 3D printing technology in finishing and painting the parts for a better look and feel of components.

- 15. Fashionable Plaster This 3D-printed cast to help repair broken bones may be the future of medical orthopedic casts. 3D-printed casts also bring out the positive potential of this emerging technology.
- 16. icial Arms for Disabled Richard Van As, a South African carpenter, assembles a Robohand and fits it to Liam Dippenaar. Liam was born without fingers on his right hand. Makerbot provided them with the 3D printing technology that they used to print the parts for the Robohand.
- 17. Bionic Ears Scientists, including an Indian-origin researcher, have created a 3D-printed bionic ear that can "hear" radio frequencies far beyond the range of normal human capability. Using off- the-shelf printing tools, the scientists at Princeton University explored 3D printing of cells and nano particles, creating the bionic ear.
- 18. Secrets of the Heart Laura Olivieri, a pediatric cardiologist at the Children's National Medical Center in Washington DC (which spent $250,000 on the 3D printer) says that these replica hearts are ideal for dry runs of complex operations, allowing the surgeon to see beforehand the exact anatomical landscape they will have to navigate.
- 19. ow Your Own Organs Surgeon Dr. Anthony Atala demonstrated during TED an early- stage experiment that could someday solve the organ-donor problem: a 3D printer that uses living cells to print out a transplantable kidney.
- 20. st Toying Crayon Creatures is a service to turn children’s drawings into figurines— nice-looking designer objects to decorate the home and office with a colorful touch of wild creativity.
- 21. mated Characters Sony pictures was the first to embrace the concept of 3D printing to create characters for the movie Pirates – A Band of Misfits.
- 22. rinting and Sustainability • 3D printing with non harmful chemicals. • 3D printing generates almost no waste during manufacturing, and does not require lubricants. • 3D Printing can be used to create replacement parts.
- 23. enges Facing 3D Printing • Intellectual property rights of the 3D Printer users. • Nearly anything can be printed by 3D Printers and this is a troubling prospect if criminals use 3D Printers to create illegal products.
