Who is going to be the first to 3D print a hull?

. Had to do it. I love seeing new hulls and ideas. Best of luck piecing the pie together.

I do not understand 3D printing. Nor how you could make a hull that would hold up............... But have not done any research either.

From the very limited research I have done, the printers that are printing carbon fiber use spools of carbon fiber and weave one layer into the shape needed and then they print the resin on top of that layer, and then repeat the process....I think.... I would imagine that they could have a very consistent ratio of carbon fiber to resin, and since the strands are placed exactly where they are needed you could create strong lightweight objects with zero excess materials. But I think that's probably easier said than done lol. Like I said, I have done barely any research. Mostly I just view videos when they are shared on facebook haha.

Thanks! Nah just been hard at work. Had to learn a whole lot of new skills to get this done.

We printed the plug because the PLA plastic we are using is chemical and solvent resistant and is deposited at a higher resolution than the CNC process we were planning on using. In the end this means less work prepping the surface of the plug before making the mold. In addition the printer was half the cost of the full size CNC machine we had plans to build and the plastic itself is cheaper than the required volume of foam. Looking forward, the ownership of our own printer means we can create any 3 dimensional object to be molded on our own time and for pennies on the dollar as we are already doing with footholds rideplates etc.

My understanding of carbon printing is that it exists to augment standard 3d printing processes for the manufacturing of usable printed parts. The example I saw was a nylon part reinforced with an insert of carbon/plastic. No directional fibers although the layers are directional.

You mentioned less work than foam for surface prep, but how long did it take/do you expect it to take to assemble all of the pieces? Are they designed to interlock? We have a small 3D printer at work and I've played with it a little. Even smaller objects take a bit of time to line up and adhere together. Then still need to shoot them with a high build and prep. However it is a consumer level printer.

I think it is a great idea, and it sounds a lot better than gluing and sanding for days and days to build a plug that size. I am just curious how it is all going to fit together.
