Laminated Object Manufacturing

Laminated Object Manufacturing (LOM ) is a production method in the field of rapid prototyping, by which a workpiece is built up in layers of paper.

Principle

The mold is made ​​of layers of paper ( also experimented with films of ceramics, plastics or aluminum) established. Each new layer is laminated on the existing layer, and then the contour cut (by means of knife, hot wire or laser). Thereafter the next layer is applied, etc.

Features

  • Existing 3D CAD data is converted to STL format. These data are supplemented with the necessary cutting lines to facilitate unpacking of the workpiece after the production.
  • Set up times can be achieved about 2-4 mm / hour (depending on the complexity of the geometry).
  • The tolerances reach 2768 medium with DIN paper.
  • Layer thickness 80 to 150 microns for paper.
  • Wall thicknesses from 2 mm, no upper limit.

Costs for installation with DIN A4 format production about 65000 euros (as of 2004)

Application

Applications are display models, casting patterns, etc.
