Which term describes a system that slices a CAD model into thin layers, then cuts out each layer from a roll of material using a laser or plotter cutter?

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

Answer: (A)

LOM, or Laminated Object Manufacturing, describes a system that takes a CAD model, slices it into thin layers, and then cuts each layer from a roll of material with a laser or plotter cutter. The layers are then laminated together to build the 3D object. This method typically uses sheet materials like paper, plastic, or metal laminates. It differs from the other terms: perspective is a way to show depth in a drawing, part drawings are technical specifications for manufacturing, and mock-ups are rough physical models for visualization rather than automated layer-by-layer fabrication.
