What is 3D printing?

• Its one rapid prototyping technologies
• It creates physical models from CAD and other
  digital datalayer by layer
• Its widely used, especially in product designing
• It reduces a lot of time and cost
• Its a developing technology

What is prototyping?

• Prototyping is a cycle that producers or
  designing teams make models for end users to
  test, evaluate, or debug, and get feedbacks then
  revise or redesign at the pre-production or
  mock-up period.

Rapid prototyping

• Stereolithography (1988)
• Fused Deposition Modeling(1990)
• Selective Laser Sintering(1992)
• 3D Printing (1997)
• Why 3D printing has become the most popular one?
• Ans faster and more inexpensive

Design Process

• Costs of changing design or finding mistakes
  increase the further into the design process you
  go
• 3D Printing helps you find mistakes early on to
  save costs

7
Design Process

• Most critical phases of design are early on
• In the first 10 of the process nearly 80 of the
  products total costs are determined
• More early designs mean better decision making

How does a 3D printer work?

WORKING OF 3D PRINTER

• The computer file travel to the 3d printing
  machine
• A layer of powder spread into the 3d printer
• Temperature is raised(laser)
• A laser harden powder and the model gets its
  shape
• The new layer of powder is spread out and the
  process is repeated many times
• The model is returned out of the printer and
  cleaned
• Model is finished by hand

Benefits of 3D Printing

• Lower cost of prototyping
• Allow more design iterations to choose from
• Decreases length of the design process
• 3D Printers are small and affordable

12
Speed to Market

• 3D Printing increases efficiency late in the
  design process
• Capable of developing parts for use in functional
  prototypes
• Some models can produce pieces that can withstand
  60 psi pressure in field tests
• Cost of late entry to market is enormous

13
Small and Affordable

• Previous rapid prototyping machines often
  required their own departments and operators
• 3D Printers can fit neatly near a workstation

14
Future Savings

• A professor at USC has now created a technology
  to eliminate the need of a laser in 3D Printers
• Selective Inhibition Sintering (SIS)
• Potential cost savings of 10,000 to 20,000 on
  the 3D Printing machines

3D Printing Success Story

• Xerox Limited produces new-generation printers,
  copiers, and document centers. The Xerox design
  team looked to a 3D printer to help improve their
  efficiency at producing prototype parts by moving
  away from the traditional machining function
  and moving more cutting edge rapid prototyping
  equipment in house.

3D Printing Success Story

• From furniture and lighting to cosmetic products
  and packaging, Karim Rashid is a high-profile
  industrial design firm with an esteemed
  reputation for communicating a contemporary view
  of the world through its unique designs.

3D Printing Success Story

• Altimate Medical Inc. manufactures
  standingframes and mobility aids for people with
  disabilities, such as spinal cord injuries,
  muscular dystrophy, multiple sclerosis and
  cerebral palsy.

3D Printing Success Story

• TaylorMade wanted pro golfer Mark OMeara to try
  out a new set of irons, OMeara asked to use them
  at the 1998 Skins Game. We had one week to
  produce two sets of ironswith club designs still
  in CAD and no tooling in place, says Jeff
  Blasius, TaylorMades senior tooling engineer.
  So we created 50 wax patterns on our 3-D
  printer, sent them to the foundry for casting and
  finishing, and delivered them to OMeara on time.
  It was the initial prototype test and Mark won
  the Skins Game with them.

3D Printing Success Story

• Guatemalan twins Maria Teresa and Maria de Jesus
  Quiej-Alvarez were born joined at the head. The
  veins draining the blood, were interwoven and fed
  into each others' circulatory system. The most
  complex part of the operation was to sort out the
  veins and reroute the twins' blood supply.
  Because the blood vessels were crisscrossed,
  tracking them using standard, two-dimensional
  x-rays was impossible.

24
Conclusion

• Nothing communicates design ideas faster than
  a three-dimensional 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 iterations
  as you like with functional parts.
