3D Printed Rudder Winglets for our Catamaran

- We have a Bambu Lab X1 Carbon 3d printer onboard. It weighs 23kg and doesn't like humidity. So why do we have something so seemingly inappropriate on Paikea? What benefits could possibly outweigh the cost of the extra weight and space it takes up on board our tiny weight-sensitive floating home?

I made some stuff with carbon/e-glass over 3D printed core. Gotta be careful about delamination as epoxy tends to not stick to the plastics. Apparently ABS that has been hit by a torch is the strongest bond. But printing ABS produces a ton of crap (VOC) that gums up the machine and also is bad for your health. Best of luck, and I'm looking forward to see the results! I'm finishing up a foil as well, but don't have time to do the finish for now.
GEEZ !! those 3D Printers are worth their weight in gold , back in my day one only had a HB Pencil and a Wooden ruler with the times table on it ha , ha , ha. ... how things have changed
3d printers are so nice. We bought one a year ago in Thailand. The biggest learning curve is cad designing but I’ve been able to make solar panel holders, fuse holders, aircon control box holders, LiFePo4 battery top covers etc. on the web I found a stl file to make new Raymarine instrument covers and printed a few of those. We have it on the back bed of our Catana 47.
Cool. Quite cool!
Personally I suspect it’s really a bit of a weighty toy with some benefits ? I know that you are refreshingly innovative and I get that the rudder winglets reduce pitching and tip vortices but there surely has to be a drag deduction and risk consequence to this addition ? I would also like to thank Anna for making these videos which we all enjoy because as sure as day follows night Shayne couldn’t be arsed with all the work involved and they are a lot of work so 🙏
The printer is great for the kids. They can learn so much and participate even more.
Ha... literally just bought X1 Carbon for my RV, been printing non-stop. Been researching how to get one in South Africa for our boat being built there. Wait till your kids realize how many free print designs are out there to print toys! Looks like ASA (instead of ABS) is going to be a good material for exterior components that need to handle sun and heat.
I was also thinking about drying chambers that you can get fairly cheap that keep the filament dry in that humid environment. Regarding CF filaments... there is a ton of strength and stiffness info out there on youtube and from what I've seen, they barely, if at all, beat PLA. PLA is just so cheap and easy to print with that I haven't spend much time with those materials. Have fun and lemme know if you need help with CAD models!
With that sweep back, you'd think most lines would just slide off... hopefully.
You are so nutty... in the good way !!! 🙃 Looking forward to the changes in Paikeas behavior and numbers with those wings
Ehhh, who needs a freezer? 3D printer fits there perfectly! 🤪 Have had cruiser friends talk about having a 3D printer aboard for years, but this is next level stuff. Can't wait to see how the winglets work and what else you come up with.
Sick! winglets is a smart idea but it does sound like lots of additional dynamic forces on the rudder stock.
great video , thanks, bit sad that they only thing that the missus can offer to entice hubby to help out is the location of chocolate biscuits......:)
The greatest secret on board Paikea is where Anna has hidden the chocolate biscuits
I am a 3d printer sailing nerd as well. I have thought of similar projects and wonder how polyester resin will react with PLA. Or epoxy for that matter. I will be anxious to see your results
We're using epoxy for winglet project and it should be fine with PLA. So should polyester resin. The biggest issue is ensuring you prepare the surface properly before laminating.
would love to see you do the process of making something with the 3D Printer .... I just can't get my head around what you start with , I'm an oldie 71
I will film one of the projects from start to finish for you. I'll find something that everyone will be interested in watching but it may take a while before I can get it up on the channel. Glad you are enjoying the videos
@@youngbarnacles WoW !! appreciate it just a small question .... will you ever sail to Fremantle as I'm in Perth and have a fair few tools you may want free as im selling up and moving to thailand to see my last years out ... battery /electric makita , bosh multi tool and accessories new ,hot air gun new... they may help in your quest , be good to see them go to someone who appreciates it most have only been used a few times , house goes on the market in June
We had wings on our 31' cat back in the 80's, lots of forces up & down. We had ours right on the bottom like an end plate. Really was surprised how much they eliminated hobby horsing.
They might be a bit large. You might get a way with smaller winglets.
That's really cool to hear👍. Yes they are a little bigger than required for an end plate. With the hope of the reduction in hobby horsing
nice. my coworking space has the same printer and I love it. best toy in a long time.
how (roughly) do you calculate that 50kg load on the winglets? and then how do you know how much glass that requires?
also, vortex and vortices :)
I do like to know too.
I looked at our upwind speeds that we do in choppy water. That defined our velocity. Then I looked at our pitching angles going up wind, by observing our instrumentation. That defined our angle of attack. The surface area and lift coefficient I know from designing the foil. This is then all modeled in XFLR5 to help include a bunch of other factors, or a fancy way of solving the lift equation.
The amount of glass it requires I did the good old gut feel from way to many years of experience..... If it was a more critical part I would look at it as a simple beam and then apply the material properties of the glass to solve the requirements.
Yes, its a vortex. For some strange reason I keep saying vortices..........
Winglets are great, but will this accelerate my Nala line organizer project?
🤣🤣🤣
Why not use the 3d printer parts as plugs and make the winglets out of foam and eglass? (You explained it at the end, i should have watched it all before commenting haha)
🤣👍
Got the modelling software, might as well have the printer to bring your inventions to real life. The winglets are a great idea, seen it done on other cats with some success, stops the pitching a bit. Never such high-tech designs though. Any luck finding some track you can use for a traveller in the back of a racing shed somewhere?
Drill some lightening holes in the paint scraper handle, man for god's sake. Ha, just realized I do the same with the laminates of little stuff. Just oh, that will be 2 layers of uni and maybe 1 EDB. Though I have to confess I don't have a feel for uni E glass, just carbon.
this channel is very refreshing in the sea of youtube idiots. good stuff.
Thanks mate

Are you considering what forces the winglet will have on the shaft bearings (pushed up and down) with the pitch forces? Also, when you turn the rudder, the winglets will have longer cords effectively creating more lift and adding additional bending forces to the shaft. MDF CNC female molds similar to what the DarkAero project used in their molds may work really well. Forged carbon fiber for the StarLink mound would work well. I made stanchion connectors out of forge cabin that are indestructible.
Wait, I’m wrong, if the foils are symmetrical then sideways movement (rudder deflection) shouldn’t cause more lift.
