Nowadays, we encounter the term climate change more and more often in the titles of articles, on television and in social networks. The concept of climate change brings with it the problem of lack of drinking water. The potential of obtaining potable water from seawater through the desalination process is the mostpromising solution to the problem of the lack of potable water, especially in arid areas. In this paper, the emphasis is on a new method of preparing membranes for desalination using 3D technology, methods of additive technology and types of membranes for desalination. Additive technology methods on which the new examples of membranes will be based are powder-based selective laser sintering (SLS), digital light processing (DLP) based on photopolymerization (photocuring), and electrospray printing. 3D technology is currently under development, therefore membranes made by conventional methods are mostly used because they are more favorable than the unexplored and expensive research of new methods of making membranes. The work will emphasize the advantages of 3D printing of membranes and the importance of better membrane characteristics such as salt rejection and water permeability. Some of the advantages of 3D printing are production speed, automation and greater environmental acceptability.
