How to prepare 3D printing metal powder

This emerging technology, 3D printing, is quickly gaining popularity in the manufacturing industry. 3D printing is called “manufacturing technological with industrial revolution importance” because it allows for the production of models, molds and parts in aerospace, automobile and bike manufacturing as well as other industries. Computer 3D modeling is used to create 3D printers. It is both a software-layered and discrete CNC forming method. It can be used with a hot melting nozzle and laser beam. This is used to create metal powder, ceramic, plastic, cell tissue, sand and other products. Each layer of material is bond to each other and then superposed together to make the final product. 3D printing demands special materials. These raw materials must be liquid, powdered or silked.

3D printer metal powder

3D printing of metal powder: A metal part. The best part in the 3D printed industry chain is the most crucial. World 3D Printing Technology Industry Conference 2013 – The world’s most respected experts on 3D printing gave an unambiguous definition of 3DPrinted Metal Powder. A group of metallic particles with a diameter less than 1 mm. There are three types of metal powder. An alloy powder and certain metallic refractory material powders. Current 3D printed metal powder materials include: cobalt chromium alloys; stainless steel; industrial steel; bronze alloys and titanium alloys. To be 3D printed, metal powder needs to have good plasticity. It must also meet requirements such as small powder size, tight particle distribution, fluidity, high bulk density, high sphericity and fluidity.

Process for the preparation of metal powder

You can divide the powder preparation into several types: one is the reduction process; the other is the electrolysis and carbonyl degradation methods. The grinding and atomization are the others. The powder obtained by the reduction or electrolysis methods and the one atomization are used widely in the powder-metallurgy business. But, both the reduction and the electrolysis are only applicable for the production of elements metal powder.

Water atomization

Water atomization can be used in the atomized production of milling. A atomized medium is not only inexpensive and simple to get, but it’s also very efficient in terms of atomization. Domestic water atomization can be used to make steel powder. It also makes diamond tools’ carcass powder. Since water has a much higher heat specific than gas, breaking down metal can result in irregular solidification, which affects powder sphericity. Alignments and metals of high activity that react with water can increase the powder’s oxygen content due to the contact with it during atomization. These difficulties limit the ability to apply water atomization to the preparation high-spherical metal powders with low oxygen contents and high sphericity.

Gas Atomization

This is the primary method for making metal and alloy particles. Basic principles of gas atomization are the following: A liquid metal stream is broken down into small droplets. This then makes it into a powder via a high velocity gas stream. This powder represents the core technology of high performance special alloy powder preparation. It has high purity, low levels of oxygen and a controlled particle size.

Laminar atomization

Nanoval Germany’s laminar technology for atomization was developed. The technology has vastly improved upon conventional nozzles. Also, this technology has low gas consumption which can lead to significant economic gains. Additionally, it is suitable for mass production of almost all metal powders. It isn’t easy to manage technical parameters, the atomization process can become unstable and outputs are small.
