In this article, we'll take a closer look at the definition of large format sand 3D printers and provide you with a comprehensive buying guide to help you find the ideal equipment and supplier in this complex market.

In terms of print size::

Generally speaking, if the print molding space of the length, width and height of one of the dimensions of 1 meter and above, it can be initially considered a large size sand 3D printer. For example, some equipment printing size of 1000mm × 800mm × 600mm, such equipment in the field of sand 3D printing belongs to the category of larger size, to meet the production needs of some medium to large sand casting parts.

In some application scenarios with higher size requirements, the length, width and height may have to reach 1.5 meters or even more than 2 meters in order to be called large size. For example, some large industrial parts of the casting sand production, the need to print the size of 2000mm × 1000mm × 1000mm and above, in order to meet the production needs of the equipment.

2. Application scenarios::

Large-size sand 3D printers are mainly used in the production of large castings, such as propellers for large ships, nacelle shells for large wind turbines, bases for large machine tools and other parts of the casting sand manufacturing. The size of these large parts is large, and traditional casting methods are difficult to meet the requirements of complex shapes and high precision, and large-size sand 3D printers can be a good solution to these problems, so sand 3D printers that can be applied to such scenarios can usually be considered large-size equipment.

3. In terms of printing capacity::

In addition to the large print size, large-size sand 3D printers also need to have high printing efficiency and stability to meet the needs of mass production. For example, it is able to complete the printing of large sand molds in a shorter period of time, and maintain stable performance over a long period of time, so that it will not suffer from precision degradation and frequent failures due to prolonged operation.

At the same time, the equipment also needs to have good material compatibility, can adapt to different kinds of sand materials, and can ensure that the printed sand has sufficient strength, air permeability and dimensional accuracy and other performance indicators.
