3D Printed Jet Engine Assembly Guide - Condensed Version
HTML-код
- Опубликовано: 19 фев 2019
- In this video, Chaps shows you a step-by-stop guide of how to assemble the 3D printed jet engine found on Thingiverse (published by CATIA5FTW).
A more detailed (and narrated) version is in the works, so keep an eye out for that.
Tips:
- Be sure to dry-fit each section first
--- Tolerances should be tight, but you should still be able to disassemble
- When gluing stationary parts, be sure to spin rotating parts to ensure that glue won't seep in and lock it up
- Angled Tweezers are very useful for nut/washer assembly
- File/Sand the LPT Bearings locations to adjust axial position of the LPT Rotors
--- There is potential for the LPT Stators to rub when the aft section is bolted on.
--- Assemble, Sand/File, & Repeat until a nice gap is achieved

Dude !! you are amazing !! Not only for that peace of art, but also synchronizing the beats with picture transitions hehe. cheers !
Bro this is sick!! I'd been looking into making this a few days ago, and you upload this today. Weird timing haha
Start printing!
It's worth it.
...and by the time you're done printing, I should have my more detailed guide up with some tips/tricks :)
@@TacCom Ok awesome! Good work dude.
@@TacCom Hey, question about supports. Do you have any photos of what these parts looked like sliced or what they looked like directly off the bed? Did you have to make extra supports beside what he'd offered? Any input is a help. Thanks man!
I'll have more images in the coming videos, but yes some additional supports are needed.
If you use his "with supports" models, you mainly need to add extra supports for the cases (the flanges)s. The combustor and Fan Stator Case also needs some.
I don't have any of the supported photos unfortunately.
I plan to grab some screenshots in my slicer as I work on the next video(s)...but nothing right now.
Nicely done. I've just finished printing all the parts and ready for assembly.
Happy for you , and how long does it take to print this jet engine ? Is it difficult to print ?
@@diy-makingstuff6267 My printer was going for almost two weeks straight with barely a break. Most of the big parts took anywhere from 16 to 20 hours.
Dosya linkini bana atabilir misiniz??
Can't link right now, but files are all in description. Alternatively, if you Google "3D printer Jet Engine", you'll find links on Thingiverse and Printables.
Wow man! That is really cool.
Nice turo fan dude been looking into joining air force cadets but yeah that's pretty sick!
Excellent. Thanks you soo much !
Big respect for your design and even bigger for sharing!
Thanks man
Enhorabuena por este trabajo y compartirlo. el mio ya esta en marcha¡
Como es que funciona ? Lleva algún tipo de motor ? O por un ventilador
@@franc4152 lleva rodamientos internos, pero es cierto que no mantiene el movimiento como en el vídeo. Intuyo que tiene que tener algún motor o algo porque si no es imposible . Yo estoy por modificarlo y meter un motor con su palanca de gases
Is there a journal reference for the creation of this project?
The real question is, how much thrust does it produce?
The only problem is that it's PLA, so it melts quite easily.
@@lukepotosky7710 use 3d printed pieces to cast aluminum or mill the parts instead, I might give this model a try using those methods soon
Really nice content dude that helped me a lot !!! However how do you you print nicely the Stator casing with the support and all ? I already watched your detailled print & processing video but I'm on S3D so I canno't use ring function nor enforced supports...
S3D is a nice paid piece of software. I would imagine that it would have some sort of custom support option.
I modeled my support regions in Fusion 360, and then imported to Slic3r for my slicing.
If S3D allows for imported support regions, I'd do that.
If not, I know that S3D has some custom-support options...I'm just not familiar with them.
An alternative is always to just use Slic3r for this 1 part. But I'd advise against that. One of the best things about this engine was problem-solving and figuring out how I wanted to get things done. So, I'd recommend trying to figure it out in S3D instead of taking a shortcut :p
Una pregunta, esta turbina funciona con motor???????
hi mate did you have any issues with the LPT R3 i have printed it and checked the files twice and its is mega tight cant get it on the spool on your other video looks like you could just slip it on when dry fitting but mine wil not go over the lip for R4 its just not big enough
Make sure you slide R3 & R4 on from the back.
Is there an outside casing for this? I am printing all the parts for this project currently. I think it would be cool to put it in the actual housing it is in on an airplane.
On thingiverse, some people have made nacelles for it.
I haven't printed any personally.
@@TacCom i will check i out thank you. Im almos done printing all the pieces for the build.
woww! fantastic!!! how many kg of pla did you used for this?
I don't recall off-hand.
I think I put the value at the beginning/end of one of the videos though.
I saw on twitter BChaps made one of these! Did he follow your guide?
sounds like a kule kat!
Can i have detail drawing ,bro ?
Thos is the type of fan I use in summer
What tools did you use to get all the bloody 2.5mm screws in the hard to reach places?
Haha, did you just post this on thingiverse? :p
The main thing was some angled tweezers.
@@TacCom Yes. Yes I did :P
Awesome, I downloaded the files but my 3D printer does not read stl files, but gcode files. How can I convert all the files at one time? Thanks
I'm actually not aware of any printer that reads raw STL files - you'll always need to convert to GCode.
And it's not really "converting" it's more "generating". It is done through slicing software. I'd suggest looking up slicers. The 2 best free ones are Cura and Prusa Slicer (what I use).
I'd recommend getting mare familiar with the processes and probabaly print a few items (starting from STL to GCODE to Print) before tackling this larger project.
Once you're more familiar with it, check out the "part 2" video I did which describes the slicing and printing aspects.
How did you make it spin by itself?
Some people have remixes to attach small servos. For the video, I just let an electric leaf blower blow into it.
how did you get the nits down on the LPT bolts , ANT man is busy and my fingers are way too big
Some angled tweezers and needle nose pliars.
Not ideal, but doable once you get used to it.
Hi, I assume you have to print some of the parts yourself, is any anywhere where you can buy the whole kit to be assembled?
All plastic parts must be printed. I'm unaware of anyone selling a kit.
All of the files are available though. You can often find people who you can pay to print the parts. Alternatively many colleges/universities and/or book stores are now starting to have 3D printing stations where you can print things yourself.
Really appreciate your reply, thanks
could I theorhetically print in the rest of the engine, seal it up and use compressed air instead of fuel?
You can totally print the rest and seal it up. Assembly would be difficult, but possible.
I'm not really following on the "use compressed air" aspect. Do you mean pumping compressed air into the combustion chamber? If so, I don't think that would work.
The engine wasn't designed for efficiency - it was designed for aesthetics. Due to the nature of the design, it is still capable of compressing the air in the HPC, extracting power from the HPT, and producing thrust with the fan. That said, the amounts are so negligible that it's almost irrelevant.
If you were to feed fuel in somehow (or even compressed air), it would need to be extremely tuned and probably an insanely low pressure in order to prevent a surge/stall.
If you want to add compressed air to the combustion chamber, in-theory you could get things to spin if you had it all tuned properly. It would probably be pretty slow though. If you're looking for it to produce any level of thrust, you'd be better off just spraying the compressed air, and using the pressure differential from that.
@@TacCom got it. was just looking for a compressed air turbine to move a lot of air at once. I got a good, hi pressure compressor, but I need the tank to be small because its going to be in a small place. I was just looking for something to turn high pressure, but small amounts of air into low-pressure, but lots of air.
@@TacCom You have some valid points, although one thing you said caught me eye, ”You’d be better off just spraying the compressed air”. That just is not true, both thermodynamically and efficiently. There is already a bunch of proof of this exact statement (People who have made compressed air powered devices, such as Tom Stanton, has debunked this exact myth)
i have assembled this fully and everything moves, but the high-pressure zone does not spin when the fan blades and low-pressure zone spin.
LP and HP spoolare separate.
HPT and HPC spin together.
LPT and Fan spin together
@@TacCom what did you use, to spin the zones? a motor?
I just blew into the front with a leaf blower.
Some mods seem like they can implement small motors though.
Is the HPC Spool supposed to rotate?????
then why bearings between spool and the shaft??
Boy spools rotate independently - at different speeds
👍👌
Does it actually provide enough thrust to make something fly or is it just a model
just a model
@@TacCom that's cool, it would be an awesome desktop item
How much filament did you use to print this Ide hate to start then run out
I have a stack up spreadsheet linked below. I don't recall the exact numbers, but it will also very GREATLY depending on how you do supports and infill.
Excuse me.Where did you put the motor at? Which motor is that?
There's no motor in here. It's all free-spinning.
I have seen a couple people who have put small motors on it though - like inside the nose-cone or something.
do that jet really works?
what kinda plastic you used to make that?
It actually spins, but no, this won't produce any thrust.
I just used regular PLA
GowTac-Com even if i make it with:(CARBON FIBER) it still won’t really work?
@@sinaprimus8212 bro the engine is cut in half...
Enrico SETIAWAN yes i know but i am creative enough to make the complete version of it do not worry
How it was moving Without any external force.
Leaf blower :p
Time to 3d print my mig15
How mch cost?
Are you using a motor? I didn't see any motors on your list.
No motors.
I think there's some mods that allow a small motor to be added though.
Mine is just used as a static desk decoration and to occasionally educate an intern or something.
What model type is the engine?
It's not modeled after any particular engine.
Can I provide a prt file?
I want to make adjustments, but there is no size, so I ask for prt.
1:03 the piece you slide inside is upside down, should be the other way
Yeah, I made 3 more of these (for my friends), and it wasn't until I did my next one that I had that face-palm moment :/
how did you made it spin?
Leaf blower :p
@@TacCom Could it be possible to make it work with a motor, controlled by Arduino ?
I think in the "remixes" section on thingiverse, someone hooked a motor up inside the nosecone (or soemthing).
It spins pretty easily, so it wouldn't need too powerful of a servo/motor, and you could certainly use an arduino or Pi of some sort.
@@TacCom Thanks alot! :)
I want to know dimensions of all parts.
Links to model for each part are in the description.
How to get that rotate ?
I used an electric leaf blower
GowTac-Com Can I buy that,I will use it to teach for my student
How much? I want to buy
If you have a printer, the total materials comes out to like $50 I think (including hardware). I don't know of anyone selling them though.
source of power?
None
1000th like
I don't have the time to 3D print this. Is anyone selling a kit, so that I can just assemble?
That was cool, but y?
I've been spending a ton of time 3D printing lately, and I've seen a lot of people ask for assembly instructions.
I don't plan on putting up much 3D printing stuff...just a couple of videos.
@@TacCom well it was super dope nonetheless
it can produce 1 gram thrust🤣😬
I made 666 likes
I want to hear it! Not that stupid music
This 3D printing technology for a given time to lower the prices of turbines that are extremely high serve but better and even instead of costing $ 4000 they should cost as $ 900 and it works better than a turbine of those to get more warranty and it is much better than buying those people what are some criminals that are 4000 3000 2525 years 25 hours of warranty and only one year of warranty and that does not serve to be replaced by something better than that the Nano impression should replace that hobby crap that Jet exists and that is much safer with the technology to have better hobby and fun
