Metal 3D Printing is a 3D technology that uses metal powders to directly print metal parts. This technology is also called Selective Laser Melting. 3D printed metal powders need to have good plasticity.
Metal powders are used in 3D printers for stainless steel, aluminum, cobalt chromium alloys, copper alloys, titanium alloys, and nickel alloys. The most significant and largest metal in engineering technology is ironbase alloy. It is widely used for the creation of complex structures.
The performance of the final product will depend on the type of metal powder and 3D printing method used.
Stainless-steel powder
Low-cost metal printing materials can be quickly and economically used for small batches of complex industrial components manufacturing.
Aluminium alloy powder
AlSi12Mg is the most commonly used aluminum alloy in metal 3D printers. Aluminosilicate 12 (lightweight additive) is used to create metal powders with excellent thermal properties. Combining silicon and magnesium gives aluminum alloys greater strength and stiffness. They are suitable for thin walls, complex geometry, and applications with high thermal properties. Aluminum alloy is an industry staple due to its low density, high specific strengths, close to or greater than high-quality steel and good plasticity. 3D printing of aluminum alloy has been shown to produce compact parts with small structures, similar to casting, or even better than cast molding parts. The cost of 3D printing can be reduced up to 30%, while the mass can be reduced 22%.
Cobalt chrome alloy powder
It is used for printing all types of artificial joints and implants in plastic surgery.
Copper alloy Powder
Copper has excellent thermal conductivity as well as electrical conductivity. It can combine design degrees to produce intricate internal structures and conformal cooling streams.
Titanium alloy powder
It is used widely in the aerospace industry. 3D printing offers many benefits. One example is the ability to replace a solid body with a complex, reasonable structure. The result is a product that is lighter and has better mechanical properties. This will not only reduce costs but also allow for lighter production.
Nickel alloy pulver
Nickel alloy’s oxidation and corrosion resistance make it ideal for harsh environments such as high temperatures and high levels of pressure. To protect the internal nickel alloy from corrosion, the alloy’s surface will passivate when it is heated. Nickel alloys have good mechanical properties across a wide range temperature ranges.
Can powdered materials be used in 3D printing?
3D data can be used to control laser beams of high energy to melt metal matrix locally and then sinter it to form solidified parts.
How do you make 3D printing metal powder?
Solid-state reduction, electrolysis and chemical are the most common methods to produce metal powders.
Many manufacturers use electrolysis or reduction methods to make elemental metal particles. However, they are not suitable in making alloy powders.
Alloy powder can be made using the atomization method.
Another way to make powdered metals is by electrolysis. Different metals can either be deposited as spongy, or powdered, depending on the electrolyte composition, temperature and concentration. These can then be washed or dried and reduced to a powdered form. This process is used to produce extremely pure metal powder. This method is used for producing highly conductive copper dust due to its high energy consumption.
The mechanical method of pulverizing the molten steel into small particles less than 150mm is known as the Atomization Method. According to the classification for crushing metal melt, the atomization process includes the second flow, centrifugal and ultrasonic atomizations, as well as vacuum atomization. Each of these atomization techniques has their own unique characteristics, and they have been used successfully in industrial production. Water-gas atomization is one of the most preferred industrial methods for making metal powder. It has simple equipment and processes, as well as low energy consumption.
Performance requirements of metal powder for 3D printing
1. Purity
Ceramic inclusions can adversely affect the performance of final products. They also have a high melting points, which makes it difficult to sinter. Powders must not contain ceramic inclusions. You must also control the nitrogen and oxygen levels. Powder preparation is done primarily by atomization. The powder is easily oxidized due to its large surface area. This index is required by customers for special applications such as aerospace. The superalloy and titanium alloy powder oxygen contents are 0.007%-0.013% respectively. The oxygen content of stainless steel powder is 0.010%-0.025%.
2. Powder fluidity, loose density
The powder’s fluidity directly influences the uniformity of powder spreading as well as the stability of powder feeding. Powder morphology, bulk density and particle size distribution are all factors that affect the fluidity. Fluidity is dependent on the size and distribution of powder particles. A larger proportion of fine powders in the particle size composition will result in a more consistent shape. Fluidity of powder increases as a function of particle density and relative density. The fluidity of powder is also reduced by the adsorption gas and water on its surface.
3. Powder particle size distribution
Different 3D printing equipments and forming processes have different requirements for powder size distribution. The most commonly used powder particle sizes in metal 3D printing are between 15-53mm (fine) and 53-105mm (“coarse”). The different energy sources used by metal printers can affect the choice of powder size for 3D printing. Because of the fine focal spot of the laser, printers can melt 15-53mm powder. Layer-by-layer powder is the preferred method for replenishment. However, powder-laying printers using electron beam energy sources have a more coarse focal spot which is better for melting coarse powder. It can be used for coarse powder between 53-105mm. As consumables for coaxial powder feeders, powders with particle sizes between 105 to 150mm are possible.
4. Powder morphology
The powder preparation method has a direct impact on the morphology. The shape of powder particles when metal gas or liquid is turned into powder is spherical. Powder particles that are made by aqueous electrolysis are dendritic. The higher the sphericity, generally speaking, the better fluidity of the powder particles. This makes it easier to lay the powder and feed it during 3D printing.
