3D Hull scan for giant 3d printer.

[Dtwigden]

Hi guys. Been lurking for a few months. Im looking to build a 3D printed hull to make a plug. Now before you all roll your eyes like I’m out of my mind, I should tell you I have a commercial sized 3D printer big enough to fit a person in.
I want to design a freeride surf hull. A bottom hull scan of a modern freeride ski would be a huge help. It doesn’t have to be a perfect scan as I can clean up the chine profiles on the computer. Happy to team up with anyone that is already involved in something like this if they’re out there. I’m based in the central valley of California if anyone has a ski in NorCal I can check out and scan that would help. Cheers

This is a great idea for someone not wanting to sand and shape. FYI there are a lot of companies that have a CNC type machine that cut's down giant foam blocks to their desired shape and then use that for their plug. Unsure if it's cheaper than 3d printing or not. Below is an example.

Be cooler if you 3d print the whole hull and run it. =)

This ^

Not like the #1 selling rec ski (spark) isn't all plastic

I could very well do that. You can take the 3D print and then vacuum laminate it with carbon fiber. But with out a good 3D scan to build from I’m just pissing in the wind.

Not cheaper when I already have the printer and design tools, but cool to know thanks.

This is cool. I would love a printer that size

What other applications are you using this for?

One off product development

Someone hook this guy up , I for one would really like to see this happen.

Do you want to make one hull or are you wanting to develop a hull? Computer scans are great if you are engineering. I can say that you need to get your hands on a hull so you can measure or scan it. You would be an industry leader if you scanned the bottoms of every hull and noted their center of gravity. All you would need at that point is a little riding experience.

I myself want a hull. But I think there is room in the market for a very affordable hull. So if I could get the help i need to collect the scans either in person or remotely I would love to develop a product to get more people into free riding and hitting the surf. It’s such a rad sport but so expensive to get into.

I think hull building would make a great hobby. There have been several builders who were relatively successful throw in the towel. It’s a tough way to even stay in business much less make a living.

 

[Dtwigden]

I think we should make open source design anyone can build from. So let’s join pool knowledge people!

I honestly think it's one of those thing you would only want to do once , just to say you did it , to be profitable it has to be scalable and this industry is too small and is there are way too many options out there right now , the amount of capitol it would take to make a hull building business profitable is mind boggling.

You have to buy 55 gallon drums of resin and fiberglass in 100 yard rolls for it to make any financial sense financially , then you have to produce and sell quickly because those 55 gallon drums you just bought have a shelf life .

If you will notice even some of the big guys like XFT and Trinity got out of it , there is know telling how many other people got out and or sold their molds over the years .

I’m more interested in giving the design to the community so anyone can make a quality ski themselves

How would it work to give it to the community?

If you have a 3d file of a hull, there really isn't any path from there to finished hull that doesn't involve a lot of work or a lot of cost or both.

You could have some cnc carved foam thing or a 3d printed mold. That's a lot of cost, and still you're not going to be laying up straight onto that, at best you still have to do all of the finishing and realistically you probably can only make a plug that way and you have to do all of the finishing, make a mold from that, then lay up your hull.

It would be less work and probably less cost to splash an existing hull that has the finishing mostly done. Especially if you plan to just scan a copy of an existing hull.

If you are planning to make design changes, then you also don't really know what that will do without building the hull and testing (maybe that is your intention).

Cool stuff to do for the sake of doing it, much respect to anybody who does it, but I'm not seeing how there is much of an opportunity to do some sort of open source hull.

But I also don't live in the world of giant 3d printers and scanning so maybe there is something I'm not seeing?

There are so many different types of filament and printing preferences that with the right combo you could lego together a hull. Maybe have to put a layer of fiber or epoxy etc over the first few of them for extra strength while you get it figured out.

Seems Like that would fit into the "lots of cost and/or lots of work"

I don't know how much that costs but I'd be shocked if it's less than buying a hull and even more shocked if the mechanical properties are competitive with fiberglass. And finish.

Maybe I will in fact be shocked. Anybody know?
