Laminated Object Manufacturing

Laminated Object Manufacturing (LOM) is a rapid prototyping and additive manufacturing technique that constructs three-dimensional objects layer by layer. Unlike other methods like stereolithography (SLA) or fused deposition modeling (FDM), LOM uses a paper-like material coated with a thermoplastic adhesive. A laser or thermal cutter precisely cuts the design onto each layer, and then a heated roller fuses the layers together, creating a solid object. This process results in strong, durable parts with a relatively smooth surface finish, though post-processing like sanding or painting might be needed for a truly refined aesthetic. The material used, often a paper-based composite, offers a good balance of strength and cost-effectiveness, making LOM suitable for a range of applications.

The significance of LOM lies in its ability to produce complex geometries with internal structures and high accuracy. Its use of readily available and relatively inexpensive materials makes it a cost-effective solution compared to some other additive manufacturing technologies. This makes LOM particularly appealing for producing functional prototypes, tooling, and even low-volume production runs. While not as widely used as some newer technologies, LOM’s strengths in producing durable parts from easily sourced materials ensures its continued relevance in specific niches within manufacturing and design, particularly where cost and material properties are key considerations. The process is also relatively straightforward to understand and implement, contributing to its enduring appeal.
