What are the key differences between additive and subtractive manufacturing?

What are the key differences between additive and subtractive manufacturing?

Additive manufacturing builds objects layer by layer, while subtractive manufacturing removes material from a solid block.

Can you give me examples of each type?

Sure! 3D printing is a common example of additive manufacturing, while CNC machining is a typical example of subtractive manufacturing.

Which method is more cost-effective?

It depends on the project scale. Additive manufacturing is often cheaper for small batches, while subtractive is better for large volumes.

What are the material limitations for each method?

Additive manufacturing can use a variety of materials like plastics and metals, but subtractive typically requires solid blocks of material.

How do these methods impact sustainability?

Additive manufacturing can reduce waste by using only the material needed, while subtractive can generate more waste during the cutting process.
