A Method for Making 3D Printing Powder

A Method for Making 3D Printing Powder
1. Vacuum atomization preparation technology
When using technology to prepare 3D printing powder, high-pressure airflow can atomize the 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 shapes during flight. Spherical particles. When using this technology for preparation, many metal and alloy powders that cannot be produced by other technologies can be prepared, and due to the fast solidification rate, segregation phenomenon can be overcome, thus enabling the preparation of many special alloy powders.
2. Hot gas atomization preparation technology
When using hot gas atomization preparation technology, the gas can be heated to 200 to 400 degrees Celsius under a certain pressure to atomize silver and gold alloys, and the resulting 3D printed powder particles have a very uniform particle size, but the average particle size and standard deviation will decrease with the depth of temperature.
3. Ultrasonic tight coupling atomization preparation technology
This 3D printing powder preparation technology can optimize the structure of tightly coupled annular groove nozzles. Therefore, the outlet velocity of the airflow can exceed the speed of sound and can effectively improve the mass flow rate of the metal. Using this to prepare 3D printing powder can greatly improve the cooling rate of the powder, thus it can generate rapid cooling or produce amorphous powder.
