Selective Laser Sintering Laser Pointer Technology
Upgrading lasers is expected to break through the bottleneck of 3D printing. Recently, the senior engineering team of the global technology giant is currently working to find a way to accelerate laser 3D printing by using a more powerful Laser pointer. Generally, during the operation of a laser 3D printing system, selective laser sintering and other technologies will be limited by the capabilities of the system laser, which will affect the 3D printing speed to a certain extent.
If the speed of 3D printing is only increased by increasing the intensity of the laser, the powder bed may be blown up. Nowadays, airlines use 3D printing technology to provide parts for airlines and face the problem of improving 3D printing lasers to save delivery time and costs. Therefore, a 3D printing system project has recently been launched, which can build a huge construction system.
It may be able to print 1-meter-long parts along all three axes. Currently, the printing system is still under development. With the continuous improvement of laser 3D printing technology, the application of this technology has been transferred from the laboratory to many manufacturing industries. Once the 3D printing system is successfully developed and put on the market, it will completely change the current manufacturing industry. Cold spraying is a material deposition process. The green laser pointer involves the use of supersonic gas jets to accelerate solid powder particles.
The particles are emitted at a speed of Mach 4 (four times the speed of sound) through a nozzle attached to the robot arm. When particles hit the substrate, they behave as liquids, rapidly cooling, and forming atomic fusions with them. Since the cold spray technology does not use the same amount of heat as welding, it is easier to restore the part to its original state using this laser engraver technology. A new layer restores the worn parts without changing the original mechanical properties.
The robot arm can be used to achieve further accuracy, and the robot arm can move and run in a specific area. The technology was used by engineers to repair gearboxes on GE90 engines, and commercial cold sprayers are now in the form of printers. A problem with current cold spray deposition is the inaccuracy of the process and the resulting need for precision ground parts.
