How to prepare 3D printing metal powder

This emerging technology, 3D printing, is rapidly growing in the manufacturing industry. It’s also known as “manufacturing technological with industrial revolution importance” because it is an efficient way to manufacture modern parts, models and molds in automotive and motorcycle manufacturing. Computer 3D modeling is used to create 3D printers. It uses software to layer discrete material and CNC forming. It can be used with a laser beam or hot melt lance. This is used to create metal powders, ceramic, plastic, cells tissue, sand, and so on. 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 powders: an alloy powder, an alloy and certain refractory material powders which have metallic properties. Current 3D printed metal powder materials include: cobalt chromium alloys and stainless steels. 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, good fluidity, and excellent sphericity.

Process for the preparation of metal powder

The current powder preparation procedure can be classified into one of the following: A reduction method; an electrolysis method; a carbonyl degradation method; a grinding process or an atomization. The powders of the atomization and electrolysis methods are used extensively in the powder industry. However, these methods cannot be applied to all alloy powders.

Water atomization

Water atomization can be used in the atomized manufacturing process. It is easy and cheap to obtain atomized medium. This makes it very efficient in terms of atomization. The domestic water method of atomization can be used for producing steel, iron-based, nickel-based, magnetic, and hard surface powders. Since water has a much higher heat specific than gas, however, the crystallization of broken metal particles during the atomization process can result in irregular solidification and a decrease in the powder’s sphericity. Alignments and metals of high activity that react with water can increase the powder’s oxygen content due to water contact during atomization. This makes it more difficult for water to be atomized in preparations of metal powders with low sphericity.

Gas Atomization

This is one way of 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 and controllable particles size have made powder the preferred technology in the development of high-performance special alloy powder preparation technologies.

Laminar atomization

Nanoval Germany’s laminar technology for atomizing metals was developed. The technology has vastly improved upon conventional nozzles. Also, this technology has significant economic benefits and low gas consumption. Although the technical control of the process can be challenging, unstable and low-quality, there are some drawbacks.
