The purpose of this project was to assess the effectiveness of designing and producing a boat hull in segments, using additive manufacturing. The group accomplished this, by completing an in-depth research into additive manufacturing processes and 3 Dimensional (3D) printing techniques. The design was to be dimensionally stable, and have a process that strives for easy repeatability and reproducibility. Evaluated was the V-Bottom, Round Bottom and Flat Bottom style. Through the use of modeling the different hull styles in SolidWorks it was determined the Flat bottom was more stable and reproducible. The hull was broken into four segments and used finger joints to align and join the segments. The 3D printer used was capable of printing Acrylonitrile styrene acrylate (ASA), Polyethylene Terephthalate (PETG), Acrylonitrile Butadiene Styrene (ABS), Nylon, Carbon Fiber and Polycarbonate. After printing with all these materials it was determined ASA would be the best fit for additive manufacturing of a boat hull. After the segments were printed and joined together with adhesives a waterproof coating was applied. The assembled hull was subjected to a series of strength tests to determine its effectiveness in this application. The finished product rode smoothly in water, was weather resistant, safe, buoyant, and reliable to manufacture.
