Building Layers: Laminated Object Manufacturing

In the realm of 3D printing, There are a variety of techniques that can be used to make objects from digital designs. One of these methods involves Laminated Object Manufacturing (LOM) which involves creating objects layer-by-layer by using a lamination technique. In the article below we’ll look into the details of LOM and show the process behind this method.

What is Laminated Object Manufacturing?

Laminated Object Manufacturing (LOM) is a method of 3D printing that produces objects by placing sheets of material on one another. The materials used typically consist of plastic or paper and are then glued to each other using an adhesive. Once the layers are placed in a stack, the object is separated from the stack with either a laser or a knife.

LOM starts with a design in digital form of the object which needs to be made. The design is converted into layers of cross-sectional design which serve as a model for an actual object. LOM is a quick process that allows you to create things that are bigger than is possible with other 3D printing methods. LOM is able to produce an array of objects for a variety of applications.

How Does Laminated Object Manufacturing Work?

Laminated Object Manufacturing (LOM) is a method of 3D printing that creates objects by layers of material one another. This step-by-step guide will explain how LOM is used:

» Design: This process begins with the creation of a digital model of the object to be designed. This design is made by using 3D modeling software. It is stored in a certain format such as STL.

» Layering: The model is then loaded into a program that splits three-dimensional models into a number of parallel cross-sectional layers. Each layer is a tiny portion of the object and the program creates a separate file for each layer.

» Printing: The process begins by placing the sheets of materials, usually plastic or paper, on an existing platform. The platform is then lowered and then an adhesive is applied on the surface. After that, the platform gets raised and it is then used to join the sheet to prior layers.

» Cutting: After the layers are placed in the stack, the object is cut from the stack by using either a laser or a knife. The remaining material is then removed, leaving the final product.

LOM is a comparatively quick process that allows you to create objects that are larger than those that can be made using other 3D printing methods. It’s also a cost-effective process that uses many different materials and materials, making it a popular choice for prototyping as well as architectural modeling.

Advantages and Disadvantages of Laminated Object Manufacturing

Laminated Object Manufacturing (LOM) is a 3D printing method that comes with its own advantages and drawbacks. Here are some principal advantages and drawbacks of LOM:

Advantages of LOM:

» Cost-efficient: LOM is a relatively low-cost 3D printing process when compared with other techniques like Stereolithography (SLA) and Selective Laser Sintering (SLS).

» Large object printing: LOM is capable of printing large-sized objects which other 3D printing technology might not be able to manage.

» Variety of material: LOM can work with an array of materials like plastic, paper and even metal. This makes it a flexible method for making various objects.

» High accuracy: LOM produces objects with excellent precision and accuracy with minimal waste of material.

Disadvantages of LOM:

» Limited resolution: LOM has a limited resolution. LOM is less than other 3D printing techniques such as SLA as well as Fused Deposition Modeling (FDM). That means the detail in the print might not be as clear.  

» Surface quality: surface that is produced by LOM printed objects isn’t like other 3D printing techniques. This might require post-processing in order to get a polished look.  

» Time-consuming process: LOM is a lengthy process because it requires cutting and stacking layers of materials, which could slow down the printing process.

» Materials Limitations: LOM is limited in the materials it is able to make use of. It’s best used with thin flat sheets of materials such as plastic and paper, which may limit the kinds of objects that can be made.  

LOM is a cost-effective, flexible method of creating large-sized objects that have high accuracy and precision. However, it comes with limitations, which include less resolution, lower quality of the surface, and limitations on materials, that may not be appropriate for all purposes.

Applications of Laminated Object Manufacturing

LOM is a tool that can design various objects for various applications. The most popular use for LOM is to create prototypes for the design of products. LOM can quickly create prototypes affordably which allows designers to try their designs prior to moving to more costly production techniques.

LOM could also be utilized to build architectural models because it is able to create massive objects that have a high degree of detail. Furthermore, LOM can be used to design models for entertainment industries including miniature sets for films and TV shows.

Conclusion

Laminated Object Manufacturing (LOM) is a 3D printing method that has been in use for more than two decades and comes with its own advantages and drawbacks. Although LOM might not be as popular as other 3D printing techniques it’s an affordable and flexible way to create large-sized items with great precision and accuracy.

LOM works with a variety of materials, such as plastic, paper, and metal, which makes it an ideal choice for prototyping as well as architectural modeling. It is, however, LOM has its limitations with regards to resolution and surface quality as well as limits to materials that may not be appropriate for all purposes. In the end, LOM is an important 3D printing technique that has distinct advantages and comes with its own specific set of applications in the field of prototyping and manufacturing.
