What are the metal powders for 3D printing?

Metal 3D printing is a 3D printing technology that uses metal powder to directly print metal parts, also known as metal powder sintering (SLM) In addition to good plasticity, 3D printing metal powder must also meet the requirements of fine particle size, narrow particle size distribution, high sphericity, good fluidity and high loose density At present, the metal powders used in most 3D printers include stainless steel, aluminum alloy, cobalt chromium alloy, copper alloy, titanium alloy and nickel alloy Iron base alloy is the most important and largest metal material in engineering technology. It is mainly used for forming complex structures and is widely used in aerospace, automobile, shipbuilding, machinery manufacturing and other industries


How to choose 3D printing metal powder

3D printing metal powder is a kind of material for 3D printing, and its quality also determines the quality of the printed products to a certain extent. Therefore, we need to pay special attention when selecting and using it. Luoyang Tongrun introduces the selection method of 3D printing metal powder.


1.3D printed metal powder should be free of impurities

Because once there are too many impurities in 3D printed metal powder, the melting point of some of the powder will rise, so that the printed products will be unqualified due to incomplete dissolution during laser dissolution.


2. Size of oxygen content

Nowadays, 3D printing metal powders are mainly made by atomization, which makes the powder have a large variable area, so the oxidation phenomenon will be more serious. Therefore, we should pay close attention to the oxygen content in the powder. For example, the oxygen content of high-temperature metal powders is generally required to be between 6 and 18 thousandths, and that of titanium alloy metal powders is generally required to be between 7 and 13 thousandths.


3. Powder particle size

The particle size of 3D printed metal powder has a significant impact on the formed product page. Generally speaking, the smaller the particle size of the powder, the better. In this way, the printed product has not only high precision but also good and very smooth surface. However, if the particle size is too small, spheroidization may occur due to uneven powder spreading during printing.


4. Powder shape

Generally speaking, spherical 3D printing metal is more suitable for printing, because the fluidity of spherical 3D printing metal powder is better. When printing, it is easier to tile, which can make the printed product more beautiful. Otherwise, if the metal powder is not paved properly, the printed product surface will appear rough.
