National Research Technological University “MISIS” (NUST “MISIS”) announces the development of a new methodology that will help improve the characteristics of parts for the aviation and space industry, created using 3D printing technology.
We are talking about obtaining high-tech structures from aluminum powder. The quality of the source material determines the reliability of the final products: the presence of even the slightest defects in the printed elements is critical for the safety of the technology being created.
Russian specialists have found a way to increase the hardness of parts printed on a 3D printer by one and a half times. For this, experts suggest adding carbon nanofibers to the aluminum powder. Interestingly, nanofibers themselves are a by-product of processing associated petroleum gas, which is usually simply burned.
“Carbon nanofibers have high thermal conductivity, which helps to minimize temperature gradients between printed layers during the synthesis of products, at the stage of selective laser melting. Due to this, the microstructure of the material can be almost completely eliminated from inhomogeneities.“, Scientists say.
It is expected that the proposed technology will improve the reliability of parts for satellites and other equipment, created using 3D printing.
