Rapid prototyping allows for the quick fabrication of physical models using 3D computer aided design data. It involves building 3D objects layer by layer through techniques like 3D printing or additive layer manufacturing. Rapid prototyping has various uses including generating molds for production, creating models for engineering and construction projects, manufacturing replacement parts, and developing medical devices and surgical planning models. Common rapid prototyping methods are stereolithography, fused deposition modeling, and selective laser sintering.

3. Rapid Prototyping
Rapid prototyping is a group of techniques used to quickly
fabricate a scale model of a physical part or assembly using
three-dimensional computer aided design (CAD) data.
Construction of the part or assembly is usually done using 3D
printing or "additive layer manufacturing" technology.

7. Purpose of Rapid Prototyping

8. Purpose of Rapid Prototyping
• Generate a mold for production

9. Types of Rapid Prototyping
• Stereolithography
• Most common type
• Uses a laser beam to
solidify liquid
photopolymer
• Fused Deposition
Modeling
• What we are using today
• Plastic is melted through
a nozzle and product is
made one layer at a
time

10. Types of Rapid Prototyping
• Selective Laser Sintering
Uses a laser beam to trace over
and seal compacted powder
You will see this machine today
It can be used to create bone
replacements.
• Laminated Object Manufacturing
Uses a laser to cut cross sections
from paper and then layers it onto
the object
Other material can be used such as
metal, plastic, and ceramics.
