What type of manufacturing is 3D printing? Subtractive manufacturing Multiplication manufacturing Division manufacturing Additive manufacturing

Understanding 3D Printing

3D printing is categorized as additive manufacturing. This process involves creating objects layer by layer, which is in contrast to traditional manufacturing methods that often involve cutting away material (subtractive manufacturing) to create the final product.

Explanation of Options

1. Subtractive Manufacturing: This method removes material from a solid block to create the desired shape. Examples include machining and drilling.

2. Multiplication Manufacturing: This term is not widely recognized or used in the context of manufacturing processes.

3. Division Manufacturing: Similar to multiplication manufacturing, this term does not have a standard application in manufacturing terminology.

4. Additive Manufacturing: This is the correct term for 3D printing, where materials are added layer by layer to build a final object. It includes techniques like fused deposition modeling (FDM) and stereolithography (SLA).

Final Answer

3D printing is categorized as additive manufacturing.
