Scientists from St. Petersburg State Electrotechnical University LETI have successfully applied reverse engineering technology to solve complex import substitution problems. The experiment was conducted in the laser technology laboratory "LETI LaserLab".
With the help of an advanced 3D scanner, it became possible to digitize objects of the most complex structure and create working drawings for reproducing parts. This method allows reproducing parts for industrial machines of domestic production, which is important for ensuring the stability of domestic industry.
The experiment was carried out on a foreign-made part of a complex asymmetrical shape, which ensures the operation of an imported machine for industrial mixing of polymers. Such parts are difficult to copy and reproduce by conventional methods, and in this case, the use of advanced digital solutions, such as a 3D scanner, becomes very relevant.
Specialists from one of the St. Petersburg enterprises turned to us with a request to help reproduce a spare part of a production machine for mixing polymers. They provided us with a sample of this damaged part, which had become unusable. Using a special 3D scanner and reverse engineering method, we created a three-dimensional computer model from an existing sample, and also made an exact copy of the spare part from stainless steel
Modern technologies, such as 3D scanning and reverse engineering, are becoming key elements of the import substitution strategy in Russian industry. The introduction of such innovative methods makes it possible to reduce dependence on foreign suppliers and ensure the stability of domestic production in the face of sanctions and limited access to manufacturer services.
Earlier, LETI scientists developed and patented a prototype navigation device for people with partial or complete vision loss based on the 2D sound visualization method.
