This emerging technology, 3D printing technology, is quickly developing in the manufacturing field. It has been called “manufacturing technological with industrial revolution importance” and is used in modern manufacturing of molds and models in aero, automobile and bike, as well as in other areas. They also play a significant role in teaching and engineering. Computer 3D designs are the foundation of 3D printers. It uses software to layer discrete material and CNC forming. It can be used with a laser beam or hot melt nozzle. This is used to create metal powders and ceramic powders as well as plastics, cell tissue, and sand. Each layer of material is bond to each other and then superposed together to produce a finished 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 of 3D printed industry chains 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 materials include: cobalt chromium alloys, stainless, industrial steels, bronze and titanium alloys, as well nickel-aluminum combinations. To be 3D printed metal powder, it must not only have high plasticity but also be fine and uniform in size.

Process for the preparation of metal powder

According to a process of preparation, the current powder preparation method can be classified into one or more of the following methods: an electrolysis, reduction, decomposition, carbonyl, grinding, atomization, or any combination thereof. The powder produced from the reduction method or the electrolysis and the the atomization methods is used extensively in the powdermetallurgy industries. However, only the elemental metal powder can be produced by the reduction or electrolysis method. This means that they are not suitable for alloy powder production.

Water atomization

Water atomization can be used in the atomized production of milling. It is easy and cheap to get atomized medium. This makes it very efficient in terms of atomization. At the moment, domestic water is used for making steel powder. Since water has a much higher heat specific than gas, the crystallization of broken metal can result in irregular solidification, which affects powder sphericity. Alignments and metals with high activity will react with water. They can increase the oxygen concentration of the powder through contact with water. These limitations make it impossible to apply water atomization during the preparation metal powders having 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. High purity, low oxygen level, controlled powder particle size, high sphericity and low production costs have made powder the preferred technology in the development of high-performance special alloy powder preparation technology.

Laminar atomization

Nanoval Germany’s laminar technology for atomization was developed. The technology has vastly improved upon conventional nozzles. Also, this technology has significant economic benefits and low gas consumption. The downside is the difficulty of technical control, unstable atomization processes, and small output.
