What is 3D printing?

1. It’s one rapid prototyping technologies2. It creates physical models from CAD and other

digital data—layer by layer3. It’s widely used, especially in product designing4. It reduces a lot of time and cost5. It’s 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)

What do you expect to create next?

• A light bulb? A motherboard? or an iPod of the nth generation?

-Go online, pay, and download the file then…produce yourself!

-No packaging, no shipping,

no assembly lines needed!

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

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

Proof Of Concept

Development Production

13

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

14

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

15

Small and Affordable

• Previous rapid prototyping machines often required their own departments and operators

• 3D Printers can fit neatly near a workstation

16

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

17

Applications of 3D Printing

• Uses– Marketing– Point of Purchase Signs– Packaging– Product Prototypes– Learning Resources

• Industries– Models

18

Industries

• Architecture & Design– Models, Topographical Maps, Building Design

• Food and Beverage– Posters, Vending Machines, Point of Sale

19

Industries, Cont.

• Consumer Products– Marketing Campaigns – R & D

• Proof of Concept

• Variations of Models

• Inexpensive Modifications

20

Industries, Cont.

• Science– Medicine– Research

• University of Illinois at Urbana – Champaign

• Miniature Reproductions of complex parts

• Spider-Web Design

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

Camera mounts for the M1 tank and Bradley fighting vehicle were built and tested directly from digital files using the Dimension 3D Printer.

23

3D Printing Success Story

A 3D printer proved to be a valuable asset and played a key role in developing concepts for the AMP Research Alloy Fuel Door for General Motors' Hummer H2 sport utility vehicle.

24

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.

25

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.

26

3D Printing Success Story

Bravilor Bonamat isEurope's leading manufacturer of coffee machines for commercial use. For more than 55 years, the family-owned company has placed a premium on innovative, user-friendly design concepts that have helped the company distinguish itself in the marketplace.

3D Printing Success Story

TaylorMade wanted pro golfer Mark O’Meara to try out a new set of irons, O’Meara asked to use them at the 1998 Skins Game. “We had one week to produce two sets of irons—with club designs still in CAD and no tooling in place,” says Jeff Blasius, TaylorMade’s 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 O’Meara 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.

29

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.
