A lightweight and durable radiator for cooling electric vehicle batteries

 E-Mail Credit: Peter the Great St.Petersburg Polytechnic University Researchers from Peter the Great St.Petersburg Polytechnic University (SPbPU) invented a durable and compact radiator for lithium-ion batteries, which in the future can be used for electric vehicles. The radiator was developed using friction stir welding technology. The development of the electric transport industry stimulates the search for new solutions in the field of rechargeable batteries with special requirements for energy consumption, weight, dimensions, and safety. These requirements are increasing every year. Its fulfillment can be achieved only by the introduction of new manufacturing technologies. For example, not the most noticeable, but an important part of such a battery is the cooling system. Thus this radiator should be compact, lightweight, and at the same time durable. To create such radiator, we used aluminum alloys and also applied friction stir welding technology says Fedor Isupov, engin

Prism 3D Printer Makes Titanium Structures

It also doubles wire feed rates (it prints faster). Mar 4th, 2021 Raisa Bestugina Researchers from Peter the Great St. Petersburg Polytechnic University (SPbPU) developed and manufactured a unique 3D printer named the Prism . Peter the Great St.Petersburg Polytechnic University Researchers from Peter the Great St.Petersburg Polytechnic University (SPbPU) have developed and manufactured Prism, a unique 3D printer. The 3D-printer was manufactured and first demonstrated on January 29, 2021. The main purpose of the developed printer is to print structures made of titanium, which is essential for various industries due to its strength properties and low specific weight. The printing system is located in a chamber with an inert atmosphere. This printer may also be used to print products made of steel, aluminum, magnesium, nickel alloys.

High- performance 3D printer for titanium structures and In situ synthesis of alloys

 E-Mail Credit: Peter the Great St.Petersburg Polytechnic University Researchers from Peter the Great St.Petersburg Polytechnic University (SPbPU) developed and manufactured a unique 3D printer named the Prism . The 3D-printer was manufactured and firstly demonstrated on January 29, 2021. The main purpose of the developed printer is to print structures made of titanium, an expensive material, but essential for various industries due to its strength properties and low specific weight. The printing system is located in a chamber with an inert atmosphere. This printer may also be used to print products made of steel, aluminum, magnesium, nickel alloys. The researchers used the wire as a raw material to ensures the high productivity of the process. The layer-by-layer deposition is performed in the 3D printer, in which the wire is melted due to the burning of an electric arc. In developed printer two wires can be fed simultaneously to increase productivity and to synthesize new alloy
