Dec 08 , 2023What are the main types of laser 3D printing technology?
Laser 3D printing technology mainly has the following types:
1. Powder sintering method: This method uses high-power lasers to sinter powdered materials into three-dimensional objects. During the sintering process, a laser beam scans against computer-generated model data, causing the powder to sinter into a solid at the focal point.
2. Light curing method: This method uses a laser beam to irradiate liquid photosensitive resin to quickly solidify it into a solid. During the stereolithography process, a laser beam scans against computer-generated model data, solidifying the object layer by layer.
3. Fused deposition modeling method: This method uses high-power lasers to melt metals, plastics and other materials and deposit them layer by layer according to computer-generated model data. During the deposition process, a laser beam scans against model data, causing the material to build up layer by layer into a three-dimensional object.
The above are the main types of laser 3D printing technology. They have their own advantages and limitations in different materials and applications.
