3D printer SPbGMTU

2023: Product Announcement

In May 2023, the presentation of the largest 3D printer in Russia took place. It was developed by specialists from RuSat - Additive Technologies and St. Petersburg Marine Technical University.

The system is designed for the manufacture of products with a maximum diameter of 2.2 m and a height of 1 m and the absence of defects in the form of large pores, cracks and foreign impurities. The equipment makes it possible to manufacture large-sized products with specified strength characteristics at high performance. Another advantage is the possibility of making bimetallic and composite articles from several grades of metal powders with different properties.

The largest 3D printer in Russia

The plant has already made a fragment of the partition-off of the internals of the energy nuclear reactor of an optimized structure with a height of 1 m using two continuously operating technological tools of the direct laser growth plant (FPL). Simply put, the printer prints with two robotic heads that are configured so as not to interfere with each other.

Working with a pair of printers speeds up the production of the model in multiples. When using powdered materials from nickel alloys, stainless and heat-resistant steels, the printing speed reaches 2.4 kg/h, so that printing an 8-ton product will take 4.5 months of continuous work. The model is obtained without large pores, extraneous intersperses and cracks. Such a method of making large metal products will be extremely efficient in terms of raw material consumption and paves the way for the creation of products from composite materials and alloys.

Direct laser cultivation is a Russian DMD-class technology that has higher performance and significantly larger product sizes. Our joint development is the first such installation where several growing tools can work at the same time, without interfering with each other with their temperature fields, "said Gleb Turichin, rector of St. Petersburg State Technical University, director and chief designer of the Institute of Laser and Welding Technologies.[1]
