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.

Rapid prototyping

• Stereolithography (1988)• Fused Deposition Modeling(1990) • Selective Laser Sintering(1992)• 3D Printing (1997)

Q: Why 3D printing has become the most popular one?

Ans: faster and more inexpensive

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.
