As the name indicates, in this process 3D shape is built by using the layer of sheets being placed over each other. The nature of this process requires continuous cutting of each layer and some sort of joining mechanisms between two lapped sheets. To assist the cutting process either a laser or mechanical knife is used. To perform the joining mechanism between sheets either an adhesive is used or welding basics are utilized.
As shown in the figure,
1 and 8 are rollers assisting movement of sheets.
2 is mechanism to assist adhesive.
3 is laser assisting the cutting process.
4 and 5 are the laser source and manipulation mechanism.
6 is the desired 3D shape.
7 is the build platform.
SHEET LAMINATION is further categorized into various options.
Laminated Object Manufacturing (LOM)
Selective Lamination Composite Object Manufacturing (SLCOM)
Computer-Aided Manufacturing of Laminated Engineering Materials (CAM-LEM)
Plastic Sheet Lamination (PSL)
Selective Deposition Lamination (SDL)
Composite Based Additive Manufacturing (CBAM)
Ultrasonic Additive Manufacturing (UAM).
Sheet lamination 3D printing is a manufacturing process that involves building up layers of material to create a three-dimensional object. This process is used in a variety of industrial applications, including prototyping, tooling, and end-use parts production. In this article, we will explore the sheet lamination 3D printing process in detail and discuss some of its key applications in the industrial sector.
The sheet lamination 3D printing process begins by creating a digital 3D model of the object that is to be printed. This model is typically created using computer-aided design (CAD) software and can be modified to meet specific design requirements. Once the model is complete, it is sliced into layers using specialized software. These layers are then used to guide the 3D printer as it builds up the object, layer by layer.
One key aspect of the sheet lamination 3D printing process is the use of sheets of material. These sheets are typically made from a variety of materials, including plastic, metal, or composite materials. The sheets are cut to the desired shape and size and are then layered together to create the finished object.
One advantage of the sheet lamination 3D printing process is that it allows for the use of a wide range of materials. This makes it suitable for a variety of applications, including prototyping, tooling, and end-use parts production. For example, sheet lamination 3D printing can be used to create prototypes of automotive parts or medical devices, or it can be used to produce small batches of custom parts for specific applications.
Another advantage of sheet lamination 3D printing is that it allows for the creation of complex shapes and structures. Because the process involves building up layers of material, it is possible to create objects with intricate details and internal structures. This makes it ideal for applications where traditional manufacturing methods are not suitable, such as the production of custom or one-off parts.
In terms of industrial applications, sheet lamination 3D printing is used in a variety of sectors, including aerospace, automotive, medical, and defense. For example, it is used to create prototypes of aircraft components, automotive parts, and medical devices. It is also used to produce custom tools and fixtures for specific manufacturing processes.
One of the main challenges with sheet lamination 3D printing is the time required to produce an object. Because the process involves building up layers of material, it can be relatively slow compared to other 3D printing technologies. However, advances in 3D printing technology are constantly being made, and it is likely that the speed of sheet lamination 3D printing will improve over time.
Another challenge is the cost of the process. Sheet lamination 3D printing can be expensive, particularly when using high-end materials. However, the cost of 3D printing is decreasing over time, and it is likely that sheet lamination 3D printing will become more affordable as the technology improves.
Overall, sheet lamination 3D printing is a versatile manufacturing process that is used in a variety of industrial applications. It allows for the creation of complex shapes and structures and can be used with a wide range of materials. While there are some challenges associated with the process, it is likely to become more widely used in the industrial sector as the technology continues to improve.
