Повысит производительность на 20-30%: в Перми применили порошковую проволоку для 3D-печати

At Perm National Research Polytechnic University (PNRPU), together with colleagues from Ural Federal University (UrFU), the wire surfacing technology for 3D printing has been improved. Specialists replaced the traditional welding wire with powder wire. This was reported by the press service of Perm Polytechnic University.

Due to the thermophysical characteristics of powder wires, as well as depending on their type, composition, and selected surfacing mode, it is possible to increase the process productivity by 10-30 percent compared to solid wires. Also, the use of certain components in the core of the wire allows obtaining almost any necessary chemical composition of the deposited material.

The new metal powder wire contains chromium, manganese, nickel, molybdenum, copper, and nitrogen. This improves the properties of the deposited material. Parts created with its use are characterized by increased strength and ductility.

Compared to existing solid welding wires of the austenitic class, the composition we developed has 20-30 percent higher strength characteristics, while maintaining high ductility. The yield strength of the experimental alloy is more than twice as high as that of the widely used steel 08Х18Н10Т.

Metal samples underwent comprehensive testing. The results showed that the use of metal powder wire allows creating defect-free blanks with improved properties. The development is planned to be used in industrial production.

Earlier, www1.ru reported that in Yekaterinburg a technology was created for 3D printing of heat-resistant alloys.
