Laminated Object ManufacturingBy Brandon BradfordComputer Integrated ManufacturingPeriod 2BThe Process
  • Sheet is adhered to a substrate with a heated roller.
  • Laser traces desired dimensions of prototype.
  • Laser cross hatches non-part area to facilitate waste removal.
  • Platform with completed layer moves down out of the way.
  • Fresh sheet of material is rolled into position.
  • Platform moves up into position to receive next layer.
  • The process is repeated.
  • Dimensions and Cost
  • Machine LOM 2030E
  • Build Volume 20" x 30" x 20“
  • Material Paper
  • Applications Produces large prototypes for visualization and assembly testing.
  • No set cost
  • Benefits of LOM
  • Low cost due to readily available raw material
  • Paper models have wood like characteristics, and may be worked and finished accordingly
  • Dimensional accuracy is slightly less than that of Stereolithography and Selective laser sintering but no milling step is necessary.
  • Relatively large parts may be made, because no chemical reaction is necessary.
  • ¡Laminated Object Manufacturing!Definitions
  • Additive-Adding material to an object usually layer by layer. Can be used as a synonym for rapid prototyping.
  • Subtractive-removing away of materials such as with mills, lathes, and drills
  • Compressive-compress large files to make them smaller.
  • Slice File-Slice Files are a unique type of file; they contain (or reference) a single piece of sample data, have a list of markers denoting "slices" of the sample, and also have a set of parameters such as tempo and time signature.
