Laminated Object Manufacturing

LOM

Instead of laying down layers of powders or melting pools of material, lamination cuts individual layers of material and then stacks them, one atop another, with a form of glue. You can create laminated objects from material foils, plastic sheets, and even common paper.

The final product, however, is only as strong as the material it's made of: paper, foil, or plastic, together with a glue.

Laminated object-manufacturing systems lack resolution on the Z axis (as the object gets taller) because each layer height is fixed at the thickness of the sheet of material plus the layer of glue.

Besides disadvantages, laminated object-manufacturing systems can be very attractive to people who need models for rapid prototyping of products and prefer inexpensive, rapid assembly to higher-resolution alternatives.

SAVINGS

Laminated Object Manufacturing (LOM) machines cut and glue thousands of sheets of material together to form solids, sometimes with standard A4 paper.
