Additive manufacturing has a wide application in numerous industries, which includes shipbuilding and marine industry. It is used for printing of spare parts, manufacturing of molds and even printing small vessels. Classification society Buerau Veritas approved the prototype of a 3D printed full-size propeller. Classification and sistematization of different 3D printers and materials used in various processes of aditivne manufacturing is yet to be made. Producing items onboard reduces the need for warehouse space, significantly reduces supply chain and simplifies installation. Implementation of 'production on demand' can greatly reduce storage costs, but it can also positively affect the environment by reducing emissions during production and generating less material waste. 3D printing has the potential to revolutionize the production as we know it. Instead of using many different subtractive machines that consume energy and produce a lot of waste, it is possible to produce geometrically more complex parts in less time and with less energy consumption. Selection of appropriate processes can lead to significant savings in consumption of energy and resources. Operating structure and applied process parameters (eg. layer thickness and print speed) also play a big role in the overall impact on the environment.
