A stereolithography 3D printer is a 3D printer that uses the stereolithography method.
The light fabrication method is a method of creating a three-dimensional structure by curing and layering layer by layer a material that is cured by exposing it to ultraviolet light. Liquid light-curable resin such as epoxy or acrylic resin is used as the material.
The stereolithography 3D printer method is the oldest of all stereolithography 3D printer technologies currently in practical use. It is the most widespread loading method in the industry.
Stereolithography 3D printers are used to verify designs, produce master models, and cast molds.
Stereolithography 3D printers can also be used to produce final products due to their ability to produce highly precise, smooth-surfaced objects.
Different types of printers and materials should be used depending on the intended use.
In the optical fabrication method, 3D data is loaded into the printer, and the liquid resin is irradiated with ultraviolet light to create the model.
The first layer is created by curing the resin by irradiating a laser beam onto a tank filled with light-curing resin liquid. Next, the resin is lowered one level from the cured stacked surface, and the next layer is cured in the same manner. This process is repeated over and over again to create the modeling.
If the layer thickness is set to be thin, extremely precise modeling is possible, and if the layer thickness is set to be thick, speedy and efficient modeling is possible.
There are several types of stereolithography 3D printers.
The following is a description of the typical modeling methods.
Stereolithography 3D printers are classified into the following two types according to the direction in which the modeling proceeds.
3D printers can be classified into several types according to the way light is irradiated. The following three are representative examples.
Stereolithography 3D printers has the following advantages and disadvantages.
Light-curing resins used have their own characteristics, and they are used according to the intended use. For example, epoxy resin has low sunlight resistance, and acrylic resin is fragile, making it unsuitable for applications where strong force is applied or durability is required.
The stereolithography 3D printers are used in the following order: creation and conversion of 3D data, modeling, and post-processing.
Three types of data, 3D data, STL data, and toolpath data, must be handled in order to proceed with stereolithography 3D printers modeling.
