Since 2024, our company has been mass producing parts manufactured using the modern additive technology Metal Binder Jetting, or 3D printing with inkjet application of a binder. This technology, when used to manufacture small parts, enables high precision and complex configurations without the use of support structures, while being 15 times faster than the market-standard SLM (Selective Laser Melting) technology.

MBJ technology is based on the layer-by-layer deposition of metal powder, which is bonded with a special liquid binder. At the start of printing, a thin layer of powder is applied to the platform, onto which a binder is sprayed, bonding the particles. A second layer of powder is then applied, and the process is repeated until the part is formed. After printing is complete, the binder is removed and sintered, resulting in a durable metal part with excellent physical and mechanical properties. The density of sintered parts ranges from 95% to 98%, while the finely dispersed structure of the material allows for strength characteristics that are at the upper limit of those of a compact material with a similar chemical composition.

MBJ additive manufacturing technology could soon replace some products manufactured using MIM (Metal Injection Molding) and Investment Casting technologies due to reduced production costs and the elimination of the need for expensive tooling. After printing, parts are sintered continuously in a protective hydrogen atmosphere. Detailed information on the sintering process and furnace operation can be found on the product's dedicated website: https://sintering.pro/.

The Keramet-Perm company accepts orders for serial production of small-sized pump stages, as well as various small-sized parts and products with axial symmetry from the following materials: AISI 304L (DIN 1.4301), AISI 316L (DIN 1.4404), MIM AISI 4140 (DIN 42CrMo4), Inconel 625 , Inconel 718, 15-5PH, 17-4PH, ASTM F75. Other chemical compositions are available upon customer approval. Our new PrimeRezist material effectively replaces the alloyed cast iron (Ni-resist) traditionally used in ESP stage castings, resulting in significant savings (up to 30%) on pump component costs. The material effectively resists sulfide and carbon dioxide corrosion, offering a combined corrosion resistance 10 times greater than Ni-resist.
