Laminated Object Manufacturing, LOM

Additive manufacturing method where the cross section of the detail is cut into a thin material which is then successively glued to the previous layer.

Illustration of Laminated Object Manufacturing, LOM

The process

Details are created on a building platform [1], which is supplied with thin construction material from a feed roller [2]. The material usually used are paper, plastic or metal foil. After each layer, the building platform is lowered and it is fed with new layer of material. The building material is usually provided with heat-activated glue and a heated lamination roller [3] is passed over the building platform to join each new layer.

A laser cutter [4] or knife, cuts a cross section of the model as well as a grid patternt in the excess material to makte it easier to remove as a post process.

Some machines have an integrated color printer which allows printing of full color models.

Advantages and disadvantages
In comparison with alternative methods
Requires no support structures
Processing only possible at the perimeter
No chemical reaction, so no chamber required
Easy to build large models
Low cost
High production speed
Difficulties in connecting the different layers
Poorer quality of the surface
Not ideal for complex geometries
Not suitable for hollow items
