Explain the process of injection molding.

• The process of injection molding involves injecting material into a mold to produce parts.

• The process of injection molding involves heating material with a torch to produce parts.

• The process of injection molding involves cutting material with a saw to produce parts.

• The process of injection molding involves sewing material together to produce parts.

What is the difference between additive and subtractive manufacturing?

• Additive manufacturing cuts away material, while subtractive manufacturing builds up layers.

• Additive manufacturing builds up layers, while subtractive manufacturing cuts away material.

• Additive manufacturing and subtractive manufacturing are the same thing.

• Additive manufacturing uses molds to create products, while subtractive manufacturing uses 3D printing.

What are the properties of metals used in manufacturing processes?
