What Is a Large Scale 3D Printer?
Large-scale 3D printers are 3D printers that specialize in the creation of large objects and are often used mainly for commercial purposes.
Until now, large objects have often been produced manually by craftsmen based on their experience. However, the use of large 3D printers enables manufacturing that is not limited by experience or time.
Large-scale 3D printers can also produce multiple small objects at the same time, making them more efficient than small-scale 3D printers.
Uses for Large 3D Printers
Figure 1. Uses of large 3D printers
Large-scale 3D printers have a variety of uses. For example, they are used to produce large prototypes, decorations, 3D signs, figures, interiors, and props. They are also used to produce casting molds for molding.
In recent years, large 3D printers have been used to model houses and bridges, and it is expected that they will be used in even more new fields in the future.
Principles of Large 3D Printers
Figure 2. Principle of large 3D printers
There are various stacking methods used in 3D printers, and the method employed differs depending on the product.
The optical molding method is a method of layering by irradiating ultraviolet light onto light-curing resin. The thermal melting and laminating method is a method in which plasticized resin is ejected from a nozzle and laminated, and since engineering plastics can be used as materials, it is effective for modeling that requires durability.
It is important to select the appropriate product according to the application of the large-sized product you want to make.

1. Large-Scale 3D Printer Materials
Large-scale 3D printers can model using a variety of materials. In addition to the materials listed below, nylon, which is flexible and used in end products, polypropylene, which is strong and resistant to acids and alkalis, and plaster can also be used.
ABS
ABS is strong against bending and stretching and is easy to polish and otherwise process. However, ABS has the disadvantage of being susceptible to moisture, which can cause deformation when making large products. Because of its low price, this material is suitable for use in in-house manufacturing.
PLA
A naturally occurring plastic material called PLA is also often used as a material for large 3D printers. Its hardness and stable output make it suitable for creating large products. However, it is not suitable for processing such as polishing.
Metal
Some advanced products can handle metal materials. Aluminum, copper, titanium, steel, etc. can be used as materials, but of course, these materials are expensive, so they are mainly used for industrial applications.
2. The Future of Large-Scale 3D Printers
Figure 3. The future of large-scale 3D printers
Large-scale 3D printers are expected to be used in a variety of fields. For example, in the construction industry, large 3D printers are being used to model houses and bridges. In the future, this is expected to help solve the shortage of engineers and realize more efficient construction.
In the automotive industry, large 3D printers are also being used to model bodies, tires, and other components. In recent years, with the trend toward EVs, the timing is right for the need for new equipment, and more attention is being paid to the use of 3D printers.
