Do you know the metal powders for 3D printing? Metal 3D printing is really a 3D printing modern technology that uses metallic powder to specifically print metal components, also called metallic powder sintering (SLM) Along with excellent plasticity, 3D printing metal powder must also meet the criteria of great particle dimension, filter particle size circulation, high sphericity, great fluidity and high loose density At present, the metal powders used in most 3D printers incorporate stainless-steel, aluminum alloy, cobalt chromium alloy, copper alloy, titanium alloy and nickel alloy Metal base alloy is the most important and greatest metallic substance in engineering technology. It is mostly used for creating complicated structures and is widely used in aerospace, car, shipbuilding, equipment manufacturing along with other sectors
How to pick 3D printing metal powder?
3D printing metal powder is a type of materials for 3D printing, along with its quality also establishes the standard of the printed products to a certain extent. Therefore, we need to pay special interest when choosing and making use of it. Luoyang Tongrun presents the selection way of 3D printing metallic powder.
1.3D published metallic powder ought to be free of pollutants
Simply because then are far too several pollutants in 3D printing metal powder, the melting reason for some of the powder will climb, in order that the imprinted goods will likely be unqualified due to incomplete dissolution in the course of laser beam dissolution.
2. Dimensions of oxygen content material
Today, 3D printing metal powders are mainly made by atomization, making the powder use a large variable region, therefore the oxidation trend will be more serious. Consequently, we must be aware of the oxygen content material in the powder. As an example, the oxygen content of substantial-temperature metal powders is usually required to be among 6 and 18 thousandths, and that of titanium alloy metal powders is generally required to be among 7 and 13 thousandths.
3. Powder particle dimension
The particle dimensions of 3D printed metal powder features a substantial effect on the formed product page. In most cases, the smaller the particle dimensions of the powder, the greater. In this way, the published product has not only high accuracy but additionally great and very sleek surface area. However, when the particle size is not big enough, spheroidization may possibly occur because of uneven powder dispersing during publishing.
4. Powder condition
Most of the time, spherical 3D printing metal is much more ideal for tynqaf printing, since the fluidity of spherical 3D printing metallic powder is much better. When stamping, it is actually easier to tile, which can make the published product much more gorgeous. Normally, if the metal powder is not paved effectively, the published product area will show up difficult.
