Constant and secure energy supply plays a critical role in the stable development of one society and economy. The Paris agreement signed in 2015 by 174 countries has also acknowledged the importance of boosting energy efficiency and developing sustainable energy technologies for mitigating global warming and reducing other effects caused by the climate change. Among all advances, adopting new manufacturing methods for energy systems has been considered as a way to contribute to such a development. Additive manufacturing, also known as 3D printing (3DP), has recently emerged as a practical strategy for optimizing fabrication process, innovating the design and enhancing energy systems´ performance.
