Specialists from Peter the Great St. Petersburg Polytechnic University have created a 3D printer that prints products made of titanium.

According to the head of the Laboratory of Light Materials and Structures of Peter the Great St. Petersburg Polytechnic University (SPbPU) Oleg Panchenko, one of the advantages of the device is increased performance. It is four times higher than its counterparts.

"Thanks to the camera with an inert atmosphere, we can print any materials. Moreover, it is possible to use two different materials during 3D printing, - he saysPanchenko. "The ability to use two different wires at once leads us to print products from innovative materials with gradient transitions in the structure."

The printer will be used to print products made of titanium. It is often used because of its high strength and small weight compared to its size. The device can print from durable materials. For example, made of steel and alloys of aluminum, magnesium and nickel.

Gorenje Panchenko said that the 3D printer was created using unique technical solutions - it produces layer-by-layer surfacing, when the wire is melted due to the burning of an electric arc. This feature distinguishes the printer from analogs that can print from titanium.

And with the use of simultaneous feeding of two types of wire, it was possible to increase the productivity of the installation and provide the possibility of creating composites.

"Thus, we can produce a four-kilogram product from titanium in one hour," he addedOleg Panchenko. - Our installation can be adapted to a specific enterprise, in particular, to increase or vice versa to reduce its working field of printing."
