The Insstek, the largest 3D printer in Russia, specializes primarily in printing large-scale parts from various types of metal to be used in the aviation, automotive, medical and space industries. In addition to its size, one of the key attributes that sets the Insstek apart from other printers on the market is its capacity to make repairs directly within its printing chamber. If, for example, a turbine blade is chipped or cracked, the blade can be inserted into the chamber, and the Insstek can print material directly into the gap to fill it.
