I 3D Printed a Boat (World's Largest Benchy!)

you ever heard the saying you don't want a boat you want a friend with a boat well what if you don't have friends if you've ever 3D printed before you probably know what this is It's a Beni boat and everyone prints it to test and calibrate their printers right I recently saw a video of a guy turning a Sandbox into a boat and it made me think could I make a boat and not just any boat you see where I'm going with this now and I've seen some people print some large ones but not really anything ever big enough for people to fit in and I have a lot of plastic if you don't know where I'm going with this now I cannot help you so it kind of works out the file already exists for a Beni so we printed one let's just see what it does this might be harder than I thought so I modified the file so now it's hollowed out try number two this kind of works so naturally next we decided to print it bigger isn't the whole point of Beni is to not use supports shut up oh okay so it's tipping but like you put weight in the back of it after this we added a keel all throughout the Beni instead of having it just be flat and it worked pretty well oh okay wait this is already so much better wait rock well there's no other scientific test to conduct so uh let's just start printing it really large now and thus chaos began we printed all the pieces with five walls to make it watertight and used 3D glute to to chemically Bond all the pieces together start putting it together we' added alignment pegs to the modified model just to line everything up but even so they were bound to be inconsistencies so some of them have gaps like this While others are put together perfectly like these two so so when people ask me how do you connect all your 3D printed Parts together sometimes I'll use Glo like we're using now but also I'll take a soldering iron and I'll melt the two pieces together so over the course of 2 days we had finally assembled the most curs looking boat I've ever seen SL roof of boat don't break look at it it's a boat bro when we put the cabin in this it's going to look so sick it's literally all just glue and Tack welds so for the cabin pieces I want to make all this removable because I kind of enjoy having a lot of room in there but we want it to look like a Bene Bo we assembled The Cabin in the same way and began sealing the seams of the outside of the main part with epoxy we do have some gaps in between these pieces we've gone ahead and welded all the plastic together super seamlessly on the inside of the boat and now on the outside to fill in some of these gaps I'm going to use some of this epoxy I don't know I just don't want to have the fiberglass a thing well you've never seen someone waterproofing a 3D printed boat with locktite before no I did mind with Gorilla [Music] Glue yeah look at him this is for the thumbnail I I've always dreamed of making a life-size VCI okay I think that was the first video we wanted to I think that was literally our first video idea and we were like that's going to take a lot of plastic and a lot of printers and guess what it took a lot of plastic and a lot of printers but before we put it in the water we wanted to ask someone a lot smarter than us what they thought about the likelihood of this if you know the draft of the hole you know down in the water goes based off of the weight that you're applying we can actually calculate pressure that's being exerted on the bottom we we just printed a small one and then we put rocks in it so we just kind of went with it and drove to a shallow portion of the lake to test it out it yes I'm going to start putting weight on it bro it's working I don't see anything seeping in no no no no no no no no no no no no hey hey hey what was that for no no no no that was not very Cash Money of you this is not easy to balance in so we did have a slight stability problem but on the bright side no matter how much we pushed down on the boat no water was seeping in wait this is it this was its maen Voyage we do have to name it the macro plastic thankfully afterwards we couldn't hear any water stuck inside the printed part so it was time to move on to adding a motor and fixing the stability stop says stop this thing's got 55 lbs of thrust now one thing that we do need to keep in mind I just thought about this uh if the boat flips over and This falls in the water it's gone wait can we not just like throw the batteries in the W it's it's generally looked down upon we're already walking a fine line with the environmentalist all right I'll stop throwing batteries in the water what we're going to use this giant PVC pipe as kind of like a p Pon so I've gone ahead and printed a bunch of these rings to fit around this 6in PVC pipe this will act as the Pontoon and then we'll have a couple 2in PVC pipes running across the bottom to act as the cage to hold the boat now this was kind of a dumb idea for whatever reason we thought it might help stabilize it from side to side but it ended up making it even more unstable plus the boat was floating on top of this thing so the boat wasn't really even boating anymore but while we were at the lake we wanted to at least try out the trolling motor and after making sure that worked it was back to the drawing board for our PVC pontoons good lighting yeah yeah if I put it like this you can actually see everything so we made these clips to hold the Pontoon pieces closer to the boat they just clip on and kind of like stay underneath this ledge so this is what it looks like if we put the full thing on there so this will clip on and back to the lake we went let do it work this works so wo bro bro I'm doing it again ohow what if the battery just [Music] died what about that 3D printed submarine idea do I have workers comp no all right let's do it thankfully Dan had caught the battery when it flipped and our testing area is pretty shallow but just so it didn't happen again we modeled and printed a battery box to hold it in place we also glued and welded down the Pontoon Clips so they wouldn't pop off again and we stripped out an old treadmill safety key switch this way we could clip the key to our clothes and the motor would turn off if you were to lean too far away or fall out we've done it get me out of here coach oh my gosh ah [Applause] bro reverse put reverse turn Captain wait is it pulling you yeah go for it Captain are you going at the fastest right now no not at all what go the fast oh this is actually really tough oh no onward Captain there's been a guy on the dock this entire time watching us what yeah what no just walked away saw all of that what do we doing now I know exactly what I want to do in college me and a bunch of friends paddle boarded all the way from one side of the lake to the other side of the lake to go get a Wendy's 4 for four I want to make that same Trek with the [Music] Beni any last oh the one piece is real for a four for four let's [Music] go see this is nice you know although it is probably kind of weird for the students walking over there we would walk over there a lot and observe a lot of people doing some really stupid stuff come like this there was literally a dog on that jet [Music] ski I think I see it I think I see [Music] it let's go the macroplastic Liv c um Dan you know what resourceful the long awaited moment can I do a four for four ah yes all is right in the world now why isn't this video sponsored by Wendy's this video is not sponsored by Wendy's Emily engineer is this Lisa hello Lisa do you remember the time we all went to Wi Beach and paddle boarded all the way to Wendy's yeah well I just did the same thing but I did it in this so uh while we went to go get ourselves a 4 for four the sun is the sun is pretty much started to wreak havoc on uh a lot of things I don't know if it got so hot that the wire is literally disconnected itself from the battery do you know how hot this battery got that's what I'm saying Dan I don't think we should ride that back not if we screwed in tight I can do it guys now this is where things got interesting we had about 40 minutes to get our kayaks back to the rental play or else we were going to get find $100 since I had the nice easy ride on the way there I let Dan ride the Beni on the way back and about a quarter of the way through our trk we noticed he was moving considerably slower than before he thinks the battery's dying what do we do yeah we we got no lights Chief oh none I mean it's still going but it's at like no power right now can we ask the rich people if they have any car batteries you guys are wasting time you should just go back I'm fine if the battery dies I'm right next to the shore so so after some convincing and now only having 25 minutes left me and Jonathan went ahead to return the kayaks this is day six of being lost at se he was not lost we could see him the entire time Emily and Jonathan have abandoned me is this my skitso arc is this where I can like just start talking to myself yeah his battery is toast boys Emily and Jonathan are are almost under the bridge right now hi I'm Dan I'm originally from Canada getting closer to the bridge [Music] Aloha what what time is [Music] it okay we're back Dan is alive and I have successfully created the best 3D printed Masterpiece to ever exist now I bet you're wondering how did you get so smart cuz only a a genius would dare to do what we just did well it's because I trained my brain with brilliant which also just so happens to be the sponsor of today's video
