st. Specialists of the Technopark Prototyping Center in St. Petersburg have created a Sokol-1 3D printer that can use metal as a printing material. In this respect informs The publication “Petersburg Diary” with reference to the words of the center director Sergei Varlamov.
Varlamov said that Sokol-1 was created to print parts of the exoskeleton that was recently presented to Russian Prime Minister Mikhail Mishustin in Norilsk. The device allows a person to lift loads up to 65 kg without much effort.
“The main difficulty is form [деталей]. It is impossible to make such parts from stainless steel by any other method other than 3D printing. Casting won’t help. Of course, milling will not work either, ”varlamov explained.
Varlamov added that the printer works on the principle of traditional laser printing. The material used is metal powder, which the laser “bakes” the shape layer by layer from base to top. The process is carried out in a chamber containing argon, an inert gas that does not allow the metal to oxidize when heated.
The development and creation of Sokol-1, St. It took about a year from the specialists of the St. Petersburg Prototyping Center. It only took two days to make the parts of the exoskeleton.
Varlamov rated the 3D printer’s development speed as “Believe me, it’s still very fast.”
According to him, the Center is ready to provide assistance to exoskeleton manufacturers, but industrial-scale production should not be relied upon.
