CNC
Our first thought was to CNC the hull. After talking to the machinist, however, we realized that this was not the most efficient option due to various reasons, namely size, cost and curvature. In order to construct a hull using the CNC process, the cost and amount of the material needed did not justify using this process above others.
MILLING
Continuing on a subtractive method of construction, we turned to milling. After consulting with the machinist again, we learned that it was possible to create the hull this way. However, when discussing the skills needed to actually do this, we found it takes a much higher skill level than any member of our team possesses and since we wanted to be part of the process, we in turn eliminated this process and turned to additive methods.
PRINTING:
FDM
The first method of printing we looked to for constructing the hull takes a computer rendering and uses plastic to create a physical model of the part. However, due to a backlog in machine usage, there was no FDM available for our initial timeline, forcing us to look toward alternative methods of printing.
STARCH PRINTING
It was always our intention to use the ZPrinter 310 Plus to create our propeller. The process to use the starch printer was actually relatively easy. We started by uploading the SolidWorks file into the 3D printing software which generated a triangulated pixel breakdown of the part. From there we just pressed start and watching it build before our eyes. In order to finish off the part we coated it in a layer of glue after we had plucked it from the chasm that was the bussom of the printer. This helped add structural integrity and element durability.
Upon consulting with our professor, we decided to manufacture the hull of the boat as well with starch printing. After following the same process as we had for the propeller, we expected it would be rapidly produced. When we returned to the machine to retrieve our part we were shocked to see it wasn’t there. After conferring with the machinist on site, we learned the printer had run out of adhesive. Without the adhesive, the starch was not able to adhere correctly to make the part despite the fact the machine believed it had completed the construction. We then tried to return to using a new FDM machine which ended up having similar issues. Thus, despite our best efforts, the hull has yet to be constructed.
