Who said that metallurgy cannot be modern?
Scientists have developed a new method of 3D printing metal that can help reduce costs and use resources more efficiently. This method, developed by a research team led by the University of Cambridge, allows structural changes to be made to metal alloys during the 3D printing process, fine-tuning their properties without the traditional "heating and forging" process that has been used for thousands of years. The results of the study are published in the journal Nature Communications.
3D printing has a number of advantages over other manufacturing methods. It allows you to create complex shapes and uses much less material than traditional methods. However, it has its drawbacks. "One of the main problems is the high cost of production due to the need to refine materials after production," said Dr Matteo Seita from the University of Cambridge.
Since the Bronze Age, metal parts have been created by heating and forging. This method allows you to shape the metal into the desired shape and give it the necessary properties, such as flexibility or strength. However, modern 3D printing techniques do not allow you to control the internal structure in the same way, which requires many improvements after printing.
Seita and his colleagues have developed a new "recipe" for 3D printing metal, which allows you to control the internal structure of the material during its melting with a laser. This method uses standard laser 3D printing technologies, but with a small change in the process.
"We found that the laser can be used as a 'microscopic hammer' to harden metal during 3D printing," Seita said. Their 3D-printed steel, developed theoretically and tested experimentally, has a performance comparable to steel produced by the traditional method.
"We believe that this method can help reduce the cost of 3D printing metal, which in turn will improve the sustainability of the steel industry," Seita added.
The research team included experts from Nanyang Technical University, the Scientific Research Agency of Singapore, the Paul Scherrer Institute, the Technical Research Center of Finland, and the Australian Nuclear Science and Technology Organization.
