3. What is 3D Printing (Additive Manufacturing)? Imagine…

5. How does it work? Layers !

6. How to 3D Print Step 1:Create a digital model and save as CAD or STL file type Step 2:Software cuts model into 2D cross-sections Step 3:Each cross-section is sent to 3D printer Step 4:Each layer fused to previous, typically using a laser Step 5:Remove excess material

8. Current Applications Rapid prototypes of designs Specialized manufacturing Prosthetics Artificial Blood Vessels

9. Future Applications Medical Housing Space
