As an advanced manufacturing process, LDS (laser direct structuring) technology has attracted much attention for its high precision and flexibility. However, in practical applications, how to optimize the processing parameters of lds laser forming materials to improve printing efficiency has become an issue worthy of in-depth discussion.
First of all, laser power is one of the key parameters. The choice of power directly affects the melting energy and forming speed. Too high power may cause the material to melt too deeply and increase residual stress, while too low power will affect the forming speed. Therefore, through experiments and simulations, finding a reasonable laser power range to take into account both melting energy and forming speed is an important step in optimizing printing efficiency.
Secondly, the scanning speed is also crucial. Too fast scanning speed may cause the molten area to fail to keep up with the diffusion of the molten pool and form a weld gap, while too slow scanning speed may cause the molten area to diffuse excessively, also increasing residual stress. Determining the optimal scanning speed range can improve printing efficiency while ensuring the forming quality.
In addition, the laser beam diameter and scanning strategy also affect the printing efficiency. Smaller laser beam diameter can achieve higher power density and smaller melting depth, improve forming accuracy, but too small diameter may cause insufficient melting. Reasonable scanning strategies, such as continuous layered, alternating or spiral methods, can reduce the gap between the molten pools and improve the forming quality.
In actual operation, it is also necessary to comprehensively consider factors such as material properties, part geometry and additional process requirements, and continuously adjust and optimize process parameters to achieve the best printing efficiency. For example, for parts with large bottom surface size and thin-walled structure, lower laser power and smaller scanning speed can be used to avoid the risk of excessive melting and deformation.
In summary, optimizing the processing parameters of LDS laser forming materials is a complex process involving many factors. By reasonably selecting and adjusting parameters such as laser power, scanning speed, laser beam diameter and scanning strategy, the printing efficiency can be significantly improved, providing strong support for the widespread application of LDS technology.
