| Question | Answer |
| Why do designers use Rapid prototyping/3D Printing? (What are its advantages?) | -To increase effective communication -To decrease development time. -To decrease costly mistakes. -To minimize engineering changes |
| What are the TWO types of Rapid prototyping/3D Printing? | -Stereolithography -Selective laser sintering |
| Describe Stereolithography | Allows 3D CAD drawings to be created in a matter of hours. The image is created on a compute, then printed out as a 3D form. |
| What are the advantages of Stereolithography? | -Quick -Cheap -Easy |
| Describe Selective Laser Sintering | 3D CAD drawings are created. Works by thin layers of powder being sintered together (melted) by a laser beam. Thousands of layers eventually make up the final product. |
| What are the advantages of Selective Laser Sintering? | -Can be done with a variety of materials -Quick Process |
