A system that virtually slices a 3D CAD model into layers and cuts out each layer from material using a laser or plotter cutter is called what?

• A. Laminated object manufacturing (LOM)
• B. Perspective
• C. Part drawings
• D. Mock-ups

Answer: (A)

This is Laminated Object Manufacturing. It builds objects by taking a 3D CAD model, slicing it into thin cross-sectional layers, and then cutting each layer from flat sheets of material with a laser or plotter. The layers are stacked and bonded together to form the final 3D part. The idea is the object is created layer by layer, like laminating sheets to rise to the full shape.

The other options don’t describe this process: perspective is about creating a 3D appearance in a drawing, not a fabrication method; part drawings are 2D technical drawings of components; mock-ups are rough physical models for visualization, not produced by layering sheets with a cutter.
