  1. Laminated Object Manufacturing By Brandon Bradford Computer Integrated Manufacturing Period 2B

  2. The 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.

  3. 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

  4. 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.

  6. 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.
