What does the following image represent?

• The type of plastic
• Slicing of print
• How much of your print will print out
• The infill (how much support the print has)

List two ways you can export (transfer files) to a 3D printer.

The goal of 3D printing is to make products on demand

• True
• False

Slicing is when...

• Layers are stacked by printing
• The 3D file gets "cut up" into hundreds/thousands of coordinates that tell the printer where to go
• You choose how much support the inside of your 3D print will have
• The 3D design software, like TinkerCAD, is used to cut things out of the print. (Grouping things together to make holes, etc.)

What are the 3 main steps of the 3D printing process?

• 3D CAD Design
• Slicing of design to create coordinates
• 3D printed model
• Choosing PLA or ABS
• Prototyping

What does CAM mean?

• Computing and Making
• Computer Aided Matching
• Computer Aided Manufacturing
