Metallic 3D Printing
Finally, the project also includes the study, among different 3D printing technologies, of those which are the most suitable to realize propeller models for experimental tests and for real-size blades.
For these propeller models, we are going to realize DMLS (Direct Metal Laser Sintering) prototypes and Polijet prototypes (this is a plastic material covered in nickel). Both these technologies potentially offer the necessary dimensional precision. For the real-size blades we are going to use the WAAM technology (Wire Arc Additive Manufacturing).
Here you can see a metallic propeller designed by Detra and realized with “Kinetic Fusion” additive technology by Titomic, and presented at “Pacific 2019 International Maritime Exposition” in Sidney.
