Release time：2025.08.14
Views：112Laser 3D printing, also known as additive manufacturing, is a technology that builds three - dimensional objects by layer - by - layer accumulation of materials. laser 3D printing has significant advantages compared with traditional subtractive manufacturing methods like cutting and grinding, which can realize the manufacturing of complex geometric shapes, breaking through the limitations of traditional manufacturing processes, and providing designers and engineers with greater space. Moreover, laser 3D printing can also reduce material waste, improve production efficiency and lower production costs.
The working principle of laser 3D printing technology is based on the high - energy features of lasers. During the printing process, the powdery and liquid material accumulate layer by layer after being rapidly melted or solidified by a precisely focused laser beam. This technique enables precise control over the shape and position of each material layer by a computer-controlled laser beam, which regulates its movement trajectory and energy output, ultimately producing a high-precision three-dimensional object.
In recent years, the application of laser 3D printing technology has grown broader and deeper in manufacturing with the continued development of laser 3D printing technology. In terms of materials, new printable materials, including metals, ceramics, plastics, and composite materials, have greatly expanded the application scope of laser 3D printing. In the medical field, laser 3D printing technology has been able to produce customized implants, prosthetics, and medical devices, providing patients with more personalized treatment plans. In the aerospace field, laser 3D printing technology can manufacture lightweight and high-strength components, improving the performance and fuel efficiency of aircraft. In the automotive manufacturing field, laser 3D printing technology enables rapid prototyping and small-batch production, accelerating the research and development as well as the market launch cycle of automobiles.
As an emerging manufacturing technology, laser 3D printing is driving transformation and development in the manufacturing industry with its unique advantages and broad application prospects. As the improvement and popularization of 3D printing technology, it could finally pave the way for a brighter future for humanity.
