However, to model a wall thickness is quite laborious as the total model should be one single watertight closed solid polysurface from a 3D modeling perspective. This means that a solid print would become way too expensive. Adding a 1 mm wall thickness is neccessary to minimize the cost of the 3D print as the printing price is mostly determined by the print powder volume.Especially the shape of the unique ice breaking hull was quite challenging. Model the hull, superstructure and details in 3D.Decide which small details have to be printed and make them thicker when necessary.The bigger the more expensive as you pay mostly the print powder volume. This depends mostly on the maximum printer size and desirable price of the 3D print.
