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)

Why 3D printing has become the most popular one?

Ans: faster and more inexpensive

Development Production

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

6

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

9

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

10

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

11

Speed to Market

3D Printing increases efficiency late in the design process

Capable of developing parts for use in functional prototypesSome models can produce pieces that can

withstand 60 psi pressure in field tests

Cost of late entry to market is enormous

12

Small and Affordable

Previous rapid prototyping machines often required their own departments and operators

3D Printers can fit neatly near a workstation

13

Future Savings

A professor at USC has now created a technology to eliminate the need of a laser in 3D PrintersSelective 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

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 StoryTaylorMade 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.

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.
