3D Powders

01

Description

Additive methods stand for the process of synthesizing a material by means of its layer-by-layer reproduction from 3D model data. These methods were such named in contrast to "subtractive" production methods, like machining.

The advantages of additive methods include: enhanced properties of finished products, less consumption of raw materials, and the ability to make complex-shaped products.

Previously, 3D printers were used in research institutes to create product prototypes, but some 10 to 15 years ago, additive methods began to be actively used in traditionally technologically advanced fields, such as the automotive, aviation, and aerospace industries, as well as in tool engineering and medicine.

specifications

JSC POLEMA, a leading manufacturer of powder metals and their products, is an excellent base for production of innovative materials for 3D printing, with the following advantages:

-- A domestic manufacturer of metal powders for 3D printing, certified by the Russian Export Center;

-- The company's professional background: 60-year long experience in metal powder production;

-- Our own research laboratory: guaranteed cutting-edge developments and possibility of import substitution;

-- Government support for projects.

In 2018, the company accomplished the project "Production of High-Alloy Metal Powders for Surfacing, Spraying, and Additive Technologies" assisted by the Industrial Development Fund. The company was the first in the Tula region to receive a special-target loan from the Industrial Development Fund. The project's investment volume exceeds 450 million rubles.

POLEMA's equipment base is unique in Russia: an atomizer, sieve and air classifiers, and a spheroidizer have been installed in the metal powder production facility. The up-to-date equipment has allowed us to expand the range of powders we produce and improve their quality, as well as to produce them on an industrial scale, resulting in products which quality can compete with and surpass imported equivalents.

In 2021, POLEMA’s 3D printing powders (Cr15Ni5Cu4B and CoCr28Mo6 alloys) came to be the first domestic materials for "growing" parts of marine and aircraft engines that were included in the restrictive lists, allowing manufacturers of gas turbine engines to replace foreign-made materials and supporting the government's import substitution program.

Currently, JSC POLEMA is the only company in Russia capable of making spherical tungsten and molybdenum powders for additive manufacturing.
