3D printing technology has completely revolutionized the process of manufacturing tangible products. A key example of a 3D printed item underlined in this article is turbine buckets. However, a drawback of this process is that it may cause distress in the components that lead to internal cracks. A team of researchers at the Technical University of Munich (TUM) has come up with a solution for the problem. They succeeded in detecting the core of stress in the internal components. 3D-printing technology is of great significance in the production process of turbine buckets.

The manufacturing process of gas turbines involves exposure to a lot of extreme conditions, such as high temperature, huge pressure, and high centrifugal force. Such extreme conditions are essential to get the maximum yield from the turbines. These turbine buckets are manufactured using the Laser Powder Bed Fusion process. In this process, the raw material used is the powdered form, whichis later properly melted through laser technology. This material is then cast and settled layer-by-layer in appropriate shape. The hollow structure of turbines not only makes the low-weight product but also provides ample strength and stability.

Dr. Tobias Fritsch, from Bundesanstalt für Materialforschung und -prüfung—a material research institute in Germany—stated that it is nearly impossible to manufacture the complex structures of the products using traditional processes of casting or milling. Employing the extreme heating and rapid cooling process for the fabrication of gas turbines result in a huge heap of residual material. The manufacturers can get rid of this residue through the downstream step of heat treatment, but it makes the process way too costly and time-consuming. Moreover, this process damages the final product by creating deformations or cracks. Hence, 3D printing will be a great alternative for fabricating high-quality turbines.
