Laminated Object Manufacturing
Laminated Object Manufacturing (LOM) is a manufacturing process from the field of rapid prototyping , with which a workpiece is built up in layers from paper.
principle
The shape is built from layers of paper (experiments are also carried out with foils made of ceramic , plastic or aluminum ). Each new layer is laminated to the existing layer and then the contour cut (using a knife , hot wire or laser ). Then the next layer is applied, etc.
features
- Existing 3D CAD data are converted into STL format . This data is supplemented by the necessary cutting lines to enable the workpiece to be unpacked after production.
- Achievable assembly times around 2–4 mm / hour (depending on the complexity of the geometry).
- The tolerances for paper reach DIN 2768 medium.
- Layer thicknesses for paper 80 to 150 µm.
- Wall thickness from 2 mm, unlimited upwards.
Costs for system with DIN A4 production format around 65,000 euros (as of 2004)
application
Applications are display models, casting models and the like. Ä.
