What is 3D Printing (Additive Manufacturing)?

•Imagine…

How does it work?

•Layers!

How to 3D PrintStep 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

Current Applications
