Laminated Object Manufacturing technology 3D prints with adhesive-coated paper, plastic, or metal laminates. After being adhered together layer by layer, these material sheets are cut into shape with a knife or a laser. LOM-created objects can then undergo post-processing adjustments such as drilling or machining.
In this reading, we’ll explore what laminated object manufacturing is, its application, history, diagram, how it works, and its advantages and disadvantages.
What is Laminated Object Manufacturing?
Laminated Object Manufacturing (LOM) is a rapid prototyping technology initially created by Helisys Inc. This rapid prototyping technique bonds and cuts sheet material using a computer-controlled laser.
Paper is the most common material used in the diverse process of laminated object manufacturing. Metallic and plastic sheets are also suitable, but cutting them is more difficult.
LOM is a quick and affordable additive manufacturing method that is mostly used for rapid prototyping as opposed to production. How accurate the final product is depends on how thick the layers of material are, but it is usually not as precise as other methods.
Application Of LOM
The process of LOM is an exceptional choice for conceptual prototyping, as it is both cost-effective and quick, even with the challenges and drawbacks. Laminated object manufacturing is another way to build scale models, and employing paper and color inks enables the production of low-cost yet visually appealing 3D promotional products.
History Of Laminated Object Manufacturing
Helisys, based in California, created and introduced LOM in 1991, the same year that Stratasys debuted fused deposition modelling (FDM). In the year 2000, Helisys changed its name to Cubic Technologies; however, it is no longer operating.
Another significant LOM hardware business, Mcor Technologies, was established in 2005 and enhanced the procedure by incorporating full-color capabilities. CleanGreen3D, an Irish firm, bought its assets in 2019 and continues to develop LOM solutions.

How Does Laminated Object Manufacturing Work?
Laminated object manufacturing involves rolling out sheets of material onto a building platform. Typically, an adhesive layer is applied to the materials, and the adhesive is melted by heating it with a feeding roller.
This allows each layer to be bonded to the one before it to form an object. A blade or laser is utilized to outline the object’s shape and to crosshatch surplus material for easier waste removal.
After adhering a layer and drawing the necessary measurements, the build platform descends to allow the heated roller to roll a second layer of material into place. This procedure is carried out repeatedly until the prototype or model is finished.
Printing something with layers of paper will give it a wood-like appearance, which may require sanding to finish. Paper objects are frequently coated with paint or lacquer to prevent moisture penetration.
Advantages Of LMO
LOM provides various benefits to industry, including the ability to produce prototypes and other items quickly and affordably. Compared to other manufacturing techniques, such as 3D printers, LOM is preferred for rapid prototyping because it allows businesses to quickly and efficiently construct a prototype using low-cost materials like paper and a computer-generated model of the product.
Both solid and hollow items, including huge parts, can be produced more quickly and affordably using the LOM process than with traditional additive manufacturing. No chemical reaction occurs during the building process, making it easy to manufacture relatively big objects.
Additionally, no support material is required because the laminated material supports itself while curing before the finished object is cut off. It is possible to work and finish paper models similarly to wood because of their wood-like properties.
Disadvantages Of LMO
As a subtractive process, Laminated Object Manufacturing makes it more difficult to create intricate geometric patterns than other 3D printing methods. This is due to the fact that it is not always feasible to remove extra material from within an object or to access its internal components.
Internal structures, undercuts, and breaking sections out of the laminate can be challenging due to the nature of LOM. Compared to stereolithography and selective laser sintering, LOM provides less dimensional accuracy.
LOM pieces may also be poorly surface-finished, and more delicate paper sections may be weaker, depending on the substance. Paper LOM components are similarly prone to moisture absorption if left untreated.
FAQs
What are the merits and demerits of laminated object manufacturing?
LOM is one of the best additive manufacturing techniques for larger structures and can reduce tooling costs and manufacturing time. However, as compared to powder-bed processes, LOM’s dimensional accuracy is lower, and its surface quality (without post-processing) is inferior.
What are the parameters for laminated object manufacturing?
The roller temperature, roller speed, roller indentation, and laser cutting time are critical process factors for producing a successful prototype in the laminated object manufacturing process (LOM), a quick manufacturing process.
Who developed laminated object manufacturing?
Helisys Inc. developed the quick prototyping method known as laminated object manufacturing (LOM).
What is LMO used for?
LOM is a fast and cheap method of additive manufacturing that is mostly used for quick prototyping rather than production. Although it is usually not as precise as other processes, the final product’s precision depends on the thickness of the material layers utilized.
