Amazing work Daniel. You're a better Engineer and Fabricator than most I've seen. I'd love to see what you could do in a shop with every tool imaginable at your disposal. Your printed parts have herpes

[@poepflater]

For your prints go through through the settings and make sure it doesn't start new layers on the outside surface... You can normally specify that it works from the inside layer or recesses first.

[@robconcep644]

I noticed that when you were polishing on the lathe, you had a long polishing strip in your hands. Try to keep the length much shorter. Long polishing strips can be very dangerous if they get tangled around the work or lathe chuck. Technically they can cause the lathe to pull you in. Very nice project and great video.

[@DktheWelder]

I thought longer was safer , I have had it grab once and pull out of my hands years ago so I’m careful not to hold on too tight ! I saw a video of a guy getting wrapped up in a lathe was awful!

Great video Dan looks like a monster. I bough some dodgy bearings the other month, they said they were deep groove but they were pretty shallow and popped out from the the thrust after a couple of runs, it might not be an issues with your bigger bearings mate, looking forward to the maiden run and all the best, Mark

[@DktheWelder]

Thanks great to hear from you! I actually copied your design a bit having the thrust bearing on the intake instead of I the flow corrector like jet skis. It is 100mm impeller I have a pretty cool plan for the motor ! I like your videos keep them coming

[@iamkian]

Hello Mark. Funny to see a comment from you here :-) We did not do much more testing as the weather and school times are not cooperating 😃

[@chris746568462]

You may be better trying an angular contact bearing in this application, the force is always going to be in axial direction. Try a 7XXX bearing.

[@culturess]

got some clean looking welds

[@DktheWelder]

thanks , 3mm aluminum is nice to weld

[@williamwestonn]

zits comes from retraction och layer shifts, the blobs are where the printer stops and starts print the outer most perimiter

[@DktheWelder]

O ok, how do you stop this? It hasn’t done it since but it seems to happen on a curved surface

[@williamwestonn]

There is no full fix, but getting better extrusion multiplyer and lowering the retraction amount will lower zits, sometimes it has to do with the material, but it could also be that you get a lot of pressure during the lifting between layer lifting. You could add coasting and minus extra restart after retraction in the travel or extrusion settings. Also mske them less visible by putting the layer starts and stops as a seam on the skarpest corner. That will make it less visual :) Search for "how to prevent blobs or zitz 3d printing" on youtube and you will have some good tips :)

[@Morrigon666]

"The disease" could be Z seam Alignment that's set on random. Put it on Sharpest Corner or User specific. Anyway Nice vid :)

[@DktheWelder]

ok thanks I will try that

[@Dynamic-Productions]

@@DktheWelder Looks more like slipping on the Z axis IMO - only say that because the bottom portion had none and the frequency increased the higher up. Signifies the problem is getting worse with Z increase; might want to check your eccentrics

I've used the hole cutting method you tried at 5:30 but with a end mill so the holes can overlap. Leaving 3-4 tabs around the circle so the piece stays centered. I tried turning it to clean up the hole like you did but with the endmill it was too sketchy even for me

[@michaelcarter3149]

You know, if you have access to or build a kiln/tempering oven. You can actually 3D print it out of metal. It's filament with metal powder in it, thus why you need to use oven. Have to melt the plastic out and get it hot enough to fuse the metal powder together. It's definitely not convenient, but still cool lol.

[@DktheWelder]

I have been watching videos on that it could be good!

[@michaelcarter3149]

@@DktheWelder The few videos I've seen on it seem to show its pretty strong. Just have to take into account the shrinkage that occurs. I think you have to make it 10% bigger to account for that, if I remember correctly? I really want to try it out, could be amazing for making pew parts. You could also do cast parts as well. How people use Styrofoam or wax to make molds (lost foam/wax casting). You can also do it with PLA filament.

[@grassroots9304]

Nicely done! The "disease" on the 3D printed part is, I think where the lines start and stop for each layer. There is a setting to align them, I believe. I have an Ender 3 V2 which I've sliced models for with both the Creality Slicer and Cura and I've not had the pimplefest you have there so I'm not sure why that is. But I've seen videos on it. I find, in Cura, under "Walls" there is a setting for "Z Seam". You may have to monkey with settings to get this setting to be displayed. It may be that setting, or it may be another...but I'm pretty sure that the defects you're seeing are from Z axis seam alignment not being set.

[@DktheWelder]

O thanks ! , I use cura now and haven’t had any problems. But in saying that I still leave most of the settings standard I am mostly a welder but 3d printers are so useful glad I got one

[@DktheWelder]

I just been keeping at it trying to keep it interesting.👍

[@gabbermaikel]

nice project again. Allready said it on facebook as wel. But if this thing works you could probably do a lost pla casting of the jet unit and have it from aluminium. Would be stronger and more durable. But for now testing with the 3d printed 1 is the way to go. Looking forward to actually testing it in the water. Also a thing to note is the intake angle. Having it scoop up water in to the jetpump can improve the performance. My jetboat has a bit of a scoop kind of thing on it as wel wich trys to direct water in to the pump if the boat is moving forward.

[@DktheWelder]

I made a scoop thing yesterday. I have been watching a lot of videos on lost PLA casting which I will try once I figure out the most effective impy

[@russcole5685]

[@Number-tf7ce]

Thanks for showing the bits that didn't work, and the steps you had to take to force them to work ;) BTW, the 'disease' on the prints is likely one of two things : 1) nozzle is running too hot or 2) filament isn't dry enough

Cool stuff man. If nobodies mentioned about the printed bubbles... Filament absorbs moisture from the air pretty bad eh. Then when the moisture passes through 200c it steams the water instantly, causing bubbling. It probably popped and snapped like wet pine in a fire while printing eh? You can dry it back out easily in a set-low oven or food dehydrator. gg & gl

[@DktheWelder]

Someone else said that , it was fresh out of the packet when it did that . It printed overnight so I didn’t notice the popping and stuff, thanks for the help I could try the oven how long do you leave it in there?

Interesting video as always. And we get to be with you even if sometimes it doesn't work. But you always find a way to do it. Keep up the good work. If the propeller explodes maybe you can have a ring around it. To connect the blades with each other. Or would that not work.

[@glumpy10]

I hate clever people like you! They make me look so dumb! Awesome project mate. Not sure if you are aware but waterjets work on flow. Using reducer nozzles won't do much for speed because water can't compress therefore wont speed up. A restricted nozzle may get your motor into the sweet spot of it's power range though and let you " Tune" it like that. For speed it may be worth looking at gearing up the engine with a belt or chain if it has the grunt. I thought of doing something like this for many years but do not have the skills even if I had the tools. Great watching some one that has both and look forward to seeing this run.

[@DktheWelder]

Haha thanks! Na tighter nozzle equals faster water speed but less volume like putting your finger over a hose . As for speed I can change the pitch of the impeller and just print another one, I tried the chain and sprocket deal on another one of my videos. I’m waiting on parts so testing it is a little way away thanks for watching!

[@michaeld954]

Lol better make 4 more and turn the tub into high powered jacuzzi jets tub

[@DktheWelder]

that would make wash time fun!

[@SirSpence99]

I'm not sure but those zits on the backside are probably because you picked "random" for the layer transitions. That looks similar to a problem I had at one point. Try "aligned" next time you are doing a rounded surface. Slic3r has that problem but it appears to be more of a bug than poor development. Besides, when doing something that requires some level of precision, aligned is easier to clean up. (It is usually more noticeable though.)

[@DktheWelder]

Ok I will look into that thanks

[@doc-holiday]

Great job. That looks very good. Your printer shouldnt be doing that i seen the quality of the print and that shouldnt be happening. Check your setting again and make sure your nozzel is clean and up to tempreture.

Hello, may I know which model of Ender 3D printer you are using? Thanks.

[@GulliJ]

Hello, I just discover channel today, check few vids, and one think disturb me. Probably for temporary test, but you have skill and tools, Tig, lathe, etc... Why not use 3d print to measure, test, and after choice, mold it in aluminium, for better durability. I know 3d filament could be strong,but if you eat wood or sand, it's done...became 3d...floats.... Except this point, the project could be excellent in results! I've not followed the first gen' but is the engine turn as fast as need to be efficient ? Turbine need speed, and a bit of torque for high pitch. Also need very tight adjust in tunnel. I've done few in different scale with metal, plastic , and both work depend on scale. So good luck and have fun Cheers from France 🇲🇫

That really sounds like a cool project! They problem with jet drives is they aren’t very efficient and with an electric boat you will need ever bit of efficient you can get to get the range . I think a surface drive prop is the most efficient but it is a pain to steer , jet units accelerate and steer really well. I think the ideal setup would be a surface drive prop on each hull that you could raise and lower and use differential thrust to steer

@@DktheWelder Yeah I saw someone else using the Creality and it looked excellent. Im getting ready to buy my first 3d printer im going to get one of those. Just not sure which version

[@DktheWelder]

@@CL-yp1bs they work really well straight out of the box I would definitely recommend one . Don’t even adjust anything and it just works probably best for a beginner like me

@@mrbamfo5000 Great to know! I am an electrical engineering student but I am wanting to get some experience with CAD as well because there are a lot of students doing dual majors with mechanical and electrical engineering. I figure a 3d printer is a great way to learn CAD and have fun doing it… the results seem to look great. I’ve been holding off ever since they first came out I wanted to wait for them to get better and all the errors ironed out.. it seems like these are a pretty refined item compared to the original 3d printers…

Man, really love the idea of an aluminum intake ^^ looks real nice and sturdy =) you don't happen to sell this ? :D

[@DktheWelder]

I made the intake aluminium so it can take a few hits to the bottom without breaking. I might sell these if I get them working well

[@T____K]

@@DktheWelder thought so, thats one weak spot if you had that one printed as well...but it works , painted PLA lasts for one summer :D looking forward to it , keep on going ;)

@@DktheWelder My jet intake is alloy with stainless grills. I smashed it of rocks for 2 years solid. Cracked the intake in half twice :) It will handly a lot more punishment than you would expect :) The weak point is the cylinder shaped impeller instead of cone shaped and no wear shroud ;) Still, it seams to work well.

@@axle.australian.patriot the pvc pipe is the wear sleeve I can just put another one in once it is worn . I will cast an aluminium impeller once I get the shape right . Do you have a JetSki unit boat?

[@axle.australian.patriot]

@@DktheWelder No, it's a 12ft alloy car topper, but re-engeneered 19mm stringers, dericane laminate skid plates, mini center console etc 40HP Yamaha outboard with an OutBoard Jet from Califorian on the bottom. I'll have to change account's, I use this one for political troll rubbish lol Should have posted in my persnal account to start with :) I'll see if I can sneak and outside link into YT :P I have a friend run a 10ft Punt (jon Boat) with a wave runner drive in the hull and does really good.

в школе проходили "архимедов винт", и говорили что он был прообразом винтов кораблей и подводных лодок, но так как архимед был дремучим и неграмотным, и все тогда были древние дремучие и неграмотные и неучёные, то они не догадались использовать архимедов винт на кораблях вместо вёсел, и вообше придать тому винту более оптимальную форму лучше подходящую для кораблей. только вот что-то мне так кажется что архимед не изобретал тот винт, и вообще рисовал не обычный винт для кораблей, а рисовал импеллер для водомётных движетелей. видимо тогда нашли остатки до-архимедовой техники от предыдущих цивилизаций. а не использовали винт по той простой причине, что двигателей подходящих не было. рабы и вёсла это банально, проще и дешевле, высокотехнологичных двигателей.
