Light-curing 3D printing technology is a rapid prototyping technology based on liquid photosensitive materials. The basic principle is to evenly spray or inject a liquid photosensitive material through a nozzle or print head onto the print bed, and then use ultraviolet (UV) or other visible light sources to irradiate the material to cure it into the desired shape in a short time. This curing process is repeated, layer by layer, to build the final 3D solid model.
The workflow of lithography 3D printing includes design, slicing, printing, and post-processing. 3D models are created using computer-aided design (CAD) software as required. Then, using slicing software, the model is divided into thin layers and a print path for each layer is generated. Next, the liquid photosensitive material is evenly sprayed or injected onto the print bed through the print head, and then the material is cured by illuminating the material with a light source. Post-processing work, such as cleaning and surface treatment, is carried out to obtain the final finished product.
3.Advantages of light-curing 3D printing
Light-curing 3D printing technology has the following advantages. It can realize the printing of complex shapes, and it can create structures that cannot be achieved with traditional manufacturing methods. Since the printing process is carried out layer by layer, a high degree of customization and rapid production can be achieved. Light-curing 3D printing can combine several parts into a single whole, reducing the assembly process. Light-curing 3D printing can save material and reduce waste because only the parts that are needed are cured, unlike traditional processing methods that need to be cut from the entire piece of material.
4.Application areas of light-curing 3D printing
Light-curing 3D printing technology has a wide range of applications in many fields. For example, in the field of industrial manufacturing, it can be used to make prototypes, injection molds, jigs, etc. In the medical field, it can be used to make tooth models, bone models, and artificial organs, among other things. In the field of architecture, it can be used to print building components, models, samples, etc. In the field of art and design, it can be used to print artworks and sculptures, etc. Light-curing 3D printing also has the potential to be used in high-tech fields such as aerospace and automobiles.
5.The development trend of light-curing 3D printing
