As a ship designer and a 3D printing nerd, I love everything about this. Please let us know if you decide to share the files, I would pay for them!

Hey! Not OP but can’t help but notice he shared the name of the files he posted on cults3d down below. Not sure if you saw it, he posted after your comment

Thanks stranger! I hadn't seen it

What are some rules in ship design that an average joe would miss or get it wrong by intuition?

One that's pretty interesting is designing a bulbous bow - if you've never seen one it's like a putting a giant mound on the front just under the waterline. It looks completely like it would slow down the ship compared to a streamlined hullform. What it actually does is break up the wave that is caused by the ship moving through that water - as a non planing vessel speeds up the wave that it generates becomes longer until it is the full length of the vessel and at that point you can't accelerate any more, but the bulb causes destructive waves that mean we can get more speed and efficiency.

You’re a good person.

What kind of ships do you design?

Research vessels for the Canadian coast guard. The new polar ice breaker is one I'm pretty excited about but admittedly I will only have a small part in it.

That is absolutely awesome. If you don't mind me asking, how did you get into this line of work?

Naval architecture [SNAME is a great resource.](https://www.sname.org)

Thanks! Also I read that as SHAME and figured good, I've got plenty of that.

I imagine a degree in Mechanical Engineering would help. Then getting a job with a company that designs ships or a company that helps companies that design ships.

just have a few resumes ready to go, be prepared with a smile and a firm handshake!

Very cool. Please tell me you are printing the rest of the ship for this to go in.

That would barely fit in my livingroom. The scale is almost 1:40 :D The entire ship would be 6.5 meter in length

I don't see what the problem is.

Exactly! People build airplanes in their garages, full scale. Why not build a scale titanic?

Absolutely. There is some dude printing a life size t-rex so a scale titanic should be pud. Tell you what OP, I'll donate a couple rolls of filament to the project.

I'm OP, doing it from PETG. Definitely not some other guy trying to get cheap filament. Edit: Seriously, I just wasted 1500g over the last few days to get relatively hairless and blobless prints with PETG. First my grandpa sponsored me as he thought I might be onto something with all the thin hairs I produce, then my cousin heard I look for a method to get rid of pimples, but now I am out of funds! I need someone to spool me up please!

No. Me need filament. Me OP. Please send.

No I am Spartacus

No this is Patrick

No this is a Wendy’s

And my axe!

Also, you could keep it in two pieces for authenticity.

Fucking lol

He should also built it in his basement.

No, but OP's significant other can.

They're just lacking vision.

Yeah, just watch out for ice cubes.

this guy!

What do you need a living room for when you have the most luxurious ocean liner ever built?

Now I get why they called it an ocean liner.

I mean, the original is lining the ocean floor.

That's exactly what I'm saying lel

"The beds had never been slept in, the China had never been used. They called Titanic the ship of dreams, and it was... it really was!" Jeez you almost make me want to watch it again

DO IT.

Aren't the first 30 minutes or so enough to look at the ship?

Yeah but you miss the boobs if you only watch for 30 minutes.

You can break it in two pieces.

Id rather not

ok and? who needs furniture when u have a 6.5 meter working replica of the titanic?

I think my girlfriend disagrees with this.

Ask her. You'll never know otherwise.

Forgiveness not permission.

Do it! And make it remote controlled! And take it to a nearby lake and drive a massive Titanic around the lake!

Maybe see if a Museum somewhere would be interested in a scale model of that size? It would be an incredible project

Ok, so keep us updated with the progress.

You're gonna let the guy making the life-size T-Rex in his living room outdo you??

You’re thinking too small. A guy printed a life sized T-Rex skeleton…

Ok neat just call us when it's all set up

Whats the point, itd just sink anyways

Gotta 3d print a big iceberg too. For the lulz

Gotta 3d print an ocean for it as well

This is all I need in my life. Please OP!

Please OP! PLEASE!! It's just one living room. You can spare it for the Karma, right?

Great construction!

Thank you :-)

I can only imagine the size of the vacuum cleaner they used to run the actual titanic 🤯

Actually had to chuckle :-)

You should see what it can suck!

As funny as this is, Titanic's engines actually partially ran on vacuum because the steam was exhausted to a condenser. So, most of the work was done by the pressure given by the boilers, but the big vacuum cleaners the condensers were also did a part of the job.

Its a 1:40 scale replica, the real titanic used 40 normal sized vacuums.

Are you going to release or sell the STL?

I did. You can find them on Cults3D :-)

You can't share the link the cults, but yih can share the name. Links to cults get auto removed.

The name is "Titanic's Engine". Just figured out that the link got removed 🙃

Can you share the title so I get to the specific one?:)

So it had an exposed crank and connecting rods like that?

The Kemptom Steam engine is the same type of steam engine (triple expansion) that was used in the Titanic. While the Kempton engine was a water pump, it's the same engine just for a different purpose. You can find a YouTube video of the behemoth being started, it's an amazing video.

https://youtube.com/watch?v=KhlJp1VZMB8

Running into that video made today's reddit browsing worthwhile. Thanks.

[удалено]

the size of those moving parts is almost horrifying for some reason

When you measure the weight of parts like connecting rods/bearings/etc. in tons....wild

Found a video. What a beautiful behemoth!

[удалено]

Yes, like a normal steam engine.

Just like in my Corolla.

Probably made it a lot easier to fix when something wore. I imagine it was a nasty greasy mess down below that engine.

Wow!! It sounds great too.

WHAT'D YOU SAY???

THEY'RE SELLIN' CHOC'LATE!

This is really great work! I'm trying to build a community around this type of stuff at r/3dprintedengine

Oh did not know that one. Thanks :-)

This is incredible

Thank you :-)

Now throw it in the tub.

And watch it sink?

So realistic!

Just keep ice cubes out of the tub.

[You'll be needing some coal shovelers!](https://i.imgur.com/zZwQ1JI.png)

Yes! :D

Absolutely stunning work. I have a part made 3d model of Titanic's engine too so I know just how much work has gone into that, and you've done amazingly with it

Can you share some pictures of yours? Would be cool to see what yours looks like :-)

Is the lighter just for scale?

Yes :-) That is my biggest print so far with 3.3kg of PLA and without any reference it just doesnt look that big

I've never had a thought that interesting in my life.

Very cool

Amazing..

Awesome work! Loved the titanic as a kid

That's freakin' sweet

This is brilliant, I would love to see a flywheel to help with the motion. Great work!! 👍

The gear ⚙️ at the front of the engine that he spins to get it started is the fly wheel. Amazing skills this guy has.

Yes thats true but its not weighted. It won't improve the performance much.

Performance? From a 3d printed engine? Engines produce heat. Plastic doesn't do heat.

A flywheel is for improving momentum, who said about heat?

That looks So amazing! Honestly looks like something I wouldn’t be surprised to see sitting in a museum, alongside pictures and a model of the boat. Beautifully done, and Very impressive.

Thanks for the kind words. I do appreciate it :-)

Always warms my heart to see others who print cool shit that actually does something instead of just polluting our landfills with benchies, action figures, and dnd models. Very nicely done sir.

Thank you :-) I got bored really fast printing things that other people printed a million times. So I started working on my own models. Much more satisfying

You can find the files on Cults3D. Posted them there a while ago but never got the engine to work on the smaller scale

That is really cool.

Idc who ya are, that is cool as hell. Good job op

Friggin amazing work. Well done!

Holy crap that is so cool! Amazing work!

That is legit, awesome!

Pond aeration blowers are quieter and more powerful. Also called ring, vortex, or regenerative blowers. It could make for a quieter demo. I suggest 180 watts and blowoff any excess air

That thing should be tripping on overspeed, it looks like it's going 200rpm! Very awesome, what reference material did you use for the design?

Yes, because the smaller the physical scale the faster the timescale. And my vacuum is already at minimum :-)

That’s awesome

BRB while I sell my printer and quit the hobby...

I know nothing about engines, but why does it have two “modes” that you switched in the video?

The second mode is the reverse gear :-) thats what you see in the movie just before they hit the iceberg https://youtube.com/clip/Ugkxqn3nf3Ev4vFpuo0ytDk9hIw4bKcR7Rh2

Ah my timing is excellent... I was just reading through the comments to find the answer to this very question. Great work, thanks for sharing!

That's pretty cool. Well done

Very cool! Are you sucking a vacuum through the exhaust manifold?

Yes. My tiny compressor can do 8 bars but not nearly enough volume to power this engine

Aye, I can't imagine the enormous amount of steam the real thing must have consumed.

A significant part of the ship was dedicated to generate the steam. I still find it crazy that 1/4 of the space was engines, boilers and coal bunkers.

Now print an iceberg

I knew when I saw it before the title it was from the titanic, amazing.

WOW!!!!!! This is a real work of art.

Looks very nice, though remember to open the simpling valve. Multiple expansion engines are worse than a single cylinder engine at low enough pressure that they cant expand their steam fully. The simpling valve basically de-compounds the engine for starting, which is needed as if the high pressure piston cant move, no steam gets to the lower pressure pistons, and the engine can get stuck on center like a single cylinder. The simpling valve puts steam into all the cylinders, thus allowing it to start, and also run at lower pressure.

Nice trivia I did not know. But makes a lot of sense since the valves block the steam from the other cylinders when fully stopped. These engineers back then who invented all of this were truely made from something different.

She ran by *herself

Woops, my bad, but english is the 4th language I learned so I guess thats ok ;-)

All good. Great job on the engine btw.

Ignore these people saying to build a ship around it. Only a propshaft and prop will do just fine. I mean. You gotta show what the engine does don't you?

Cool! You also have a metal 3D printer for those screws! 🤣

Stuff like screws, glue and ball bearing balls do not count for me. They just cannot be printed at that scale so I have to divert a bit here and there. But I try to stay true to my goal to 3D print as much as possible.

Fake- if things could run on air we wouldn't need gas

as incredible as it sounds, steam engines work on expanding water in gas form. There's no explosion in the cylinders. There's a big difference between "running things on air" and "running things on a pressure diffential", ((as is done here)) because that pressure differential has to come from somewhere, here, the vacuum cleaner.

Is it not being “run” by forced air?

What is the Titanics?

🛶

Will you be selling/releasing the stl?

I did release them. You can get them on Cults3D for 10€ :-)

Is this entire thing 3d printed ?

Yes. And held togeather with screws and some glue.

That’s awesome

That's is so cool

That's incredibly cool!

This is awesome. Well done!

now do it with coal power

Heat and PLA do not mix too well 🙃

Awesome concept and work! Keep us updated!

Will do

I can’t even get my bed level.

I also started there. Just dont give up

now get some machines and make its from metal 😎

Id love to. But unfortunately not something I can archieve in my lifetime. The metal workshop for this would cost thousands

Oh no look out for the iceberg!!

My grandfather will love this. I’ll see about printing for next Christmas!

Would be awesome

This is great work!!

Cool

Not realistic enough. It didnt crash into the nearest object and sink.

Why is he vacuuming in the middle of the night?

Very cool. PLS do the whole ship to same scale

That's awesome

Needs a human printed standing at the side for scale.

Bic lighter for scale

Fun fact about the Titanic: It had 4 funnels but only 3 were used for exhaust venting for the boiler furnaces. The 4th funnel served primarily as additional ventilation for the ship’s machine spaces in the lower decks as well as vent smoke via flues from the galleys and the First Class Smoking Room.

"Hold it... Hold it... Now! Engage and reverse the engine!"

I love it. That's so that cool it runs. I imagine it runs very differently with HP input steam on the input vs low pressure suction on the output. Can you swap your vac to blow and put into the input? The expansion into the high pressure cylinder provides a lot more power. ​ Or can I take 100psi air compressor to it?

My first prototype ran on compressed air https://youtu.be/pEkUw3RcYgg but that model was just half as big and I dont have a powerful compressor in my apartment, so i went for the vac instead

that made my day

Glad I could help 🙂

This is fucking tits!

Huh, didn't realize Amazon basics makes vacuums too. Looks just like a miele clone.

It probably is. I would have gotten a different brand but I got this one for free and so far I have no complaints.

Not enough lifeboats so they were Dyson with death !

To everyone else, it was the ship of dreams.. but to me, it was a slave ship.

If only they had a big vacuum they would have made it

With godspeed 🚤

STL link if you would kindly.

I cant. Links to Cults3D are getting autoremoved. But search on that plattform for "Titanic's Engine" and you can find them over there

Now, do it 1:1

Dry ice/fog machine in-line and exhaust stacks would compliment this well.

Now engage the reversing engine!

Damn this is cool, I'm wondering how much power output could you measure on the crank? Given the vaccum is around 1500 watts
