Powders for 3D printing

•     

     

Additive technology is a process of a material synthesis layer by layer based on 3D model data. It received its name against subtractive technologies production technologies, particularly, machining. Advantages of additive technologies are enhanced characteristics of finished products, economy of raw material, an opportunity to produce items with a complex geometry.

Before researchers used to apply 3D printers for prototyping, but about 10 - 15 years ago the traditionally advanced industries, such as automotive, aerospace, instrument engineering and medicine started using these technologies actively. 

JSC POLEMA, being a leading producer of powder materials and products from them in Russia, is a perfect base for manufacturing innovative materials for 3D printing. It owns the following advantages:  

• A reliable manufacturer of metal powders for 3D printing, MIM technologies that is certified by the Russian Export Center;
• The factory’s competence: 60-year experience in production of metal powders
• In-house Research Laboratory that guarantees use of the newest developments;
• State support.

In 2018 the factory realized the project “Production of metal high-alloyed powders for weld-deposition, spraying and additive technologies”. 

POLEMA’s equipment stock is unique for Russia: an atomizer, sieving and air classifier and a spheroidizing unit are set at the metal powders production site. The up-to-date equipment allowed us to expand the variety of manufactured powders and to enhance their quality.

 

You can see more information on production process and take a look at the list of powders for 3D printing produced by our company in our presentation.
