Manufacturing method of 3D printing powder
Vacuum atomization preparation technology
When using technology to prepare 3D printing powder, high-pressure air flow can atomize metal liquid under the protection of gas and decompose it into a large number of small droplets. These droplets will solidify into spherical or sub-spherical during flight. Spherical particles. When this technology is used for preparation, many metal and alloy powders that cannot be produced by other technologies can be prepared, and the segregation phenomenon can be overcome due to the rapid solidification speed, so many special alloy powders can be prepared.
Hot gas atomization preparation technology
When using the hot gas atomization preparation technology, the gas can be heated to 200 to 400 degrees Celsius under a certain pressure to atomize the silver alloy and gold alloy, and the resulting 3D printing powder particles have a very uniform particle size, but the average particle size and standard deviation will decrease with the depth of temperature.
Ultrasonic tight coupling atomization preparation technology
This 3D printing powder preparation technology can optimize the structure of tightly coupled annular groove nozzle. Therefore, the outlet velocity of air flow can exceed the velocity of sound, and can also effectively improve the mass flow of metal. Using this to prepare 3D printing powder can greatly improve the cooling rate of the powder, so it can produce rapid cooling or amorphous powder.
