SLS 3D printing equipment is usually equipped with a single laser, and when a larger printing area or improved printing efficiency is required, the number of lasers can be increased. Therefore, currently dual laser SLS 3D printers are mainly divided into two types:
The main purpose of increasing the number of laser systems and scanning systems is to increase the printing area. Such devices can print models with a larger length, but with narrow overlap areas in the middle of the printing area, and the spliced parts of each layer are in the same position, which may affect the appearance and strength performance of the model's spliced parts.
The main purpose of increasing the number of laser systems and scanning systems is to improve the forming efficiency. The printing area of such devices does not increase significantly, but the production efficiency will be improved. For example, the dual laser device P550DL from TPM3D has an overlap area of about 300mm for laser scanning, and the two lasers print parts using intelligent cooperative scanning. According to the size and distribution of the parts, the system automatically plans the work of the two lasers, thus improving the forming efficiency. In addition, adjusting the splicing position of the parts to be spliced and printed can avoid each layer being in the same position, and the parts will have better strength and surface quality.
In summary, the characteristics and advantages of the TPM3D Dual Laser SLS 3D printer include a large printing area, high forming efficiency, and optimized splicing area, which can meet customers' demands for large-scale, high-efficiency, and high-quality 3D printing.
