3d Printed Turbofan Engine 

Hello Chris! You Sir are a legend and a warm welcome from me here in Brunei. Great to hear from the designer, and what a design that was! So cool LOL! Very well done and very clever! The whole thing now stands on my desk and will feature in the background of many videos hopefully. I have only just found you on Thingiverse and linked your design there too. Thank you for taking the time to drop by and say hello. Kind Regards Karl.

Hello Chris, this masters peice of a design. With your permission I would love to build it out to build it and actually power it. We are hoping to build the first jet powered aircraft in Nigeria 🇳🇬. This is a huge inspiration

Chris, do you have a design for the fan stator casing, compressor casing, turbine casing, etc., in two halves that can be assembled together to create a 360 enclo sure??

@@timothycatchpole7948 Hi, did you get a reply or did you find them? The Thingiverse files don't show these files, as far as I can find.

It's a fantastic, fun build! Enjoy and at the end you will have a gorgeous piece of aviation art!

That sir is a very cool idea!

Or even enlarge the print % and go 1:1 of the real thing!

That would be awesome! I was thinking the same thing !

Thank you for the kind words, Karl

Hi Brian, I would have lived to see that! This is just a plastic version, but I'm so impressed with it. 3d printing is moving fast!

Hi Patrick, This was just for a Prop in the background. Loved the design and build. However, since making this video, i know have turbo prop engines, helicopter gearboxes to create, the list is growing fast. My place will look like my old college training room with all the parts of 3d printed aircraft components. Kind Regards Karl

Hi Donald, thank you for the advice! Kind Regards Karl

I get this comment a lot, in my trade I would have said operational if it was going to burn fuel. Working as it demonstrates the internal workings of the engine. But yes, regardless, its a beautiful model that Bob and Chris created. Kind Regards Karl

@@helimech8152 While a title change probably wouldn't fetch as many views, "3D printed interactive cutaway jet engine" would snag more keywords and be a bit more honest.

it all so says 3d printed, do u seriously think u can a jet working if its 3d printed

@@emptymannull 110% is impossible, cant go over 100%, numbnuts

@@jimmyjames1807 Why would something being 3D printed preclude it from being a functional part? Different manufacturers can print some version of everything '3D' now, from houses to organs to jet and rocket engine parts, and you'll find them more than suitably functional.

Thank you, This is such a fun build and brings back many fond memories. I can only imaginbe the quality of the prints on the X1! Have fun with this one!

Hello and thank you. All advice is greatly accepted and I will give it a go.

@@helimech8152 which kind of adhesive you use, may I ask

Hi Zach, this was a fun build. Funny, I was just packing this up last night ready for our move back to the UK.

I think my original reply was auto deleted by RU-vid, I'll try again but separate them into multiple replies as I have a guess as to why a program would auto-delete it.

Special Note: I applied for a 3D printer very quickly before work began today. I may have not remembered the details accurately about original build and I don't tweet anymore, so it's a mess of replies to replies. If you are unhappy with my tweets for printer for any reason whatsoever, or just simply don't think I should apply with that goal, or have any other issue, just let me know and I will delete the tweets as soon as I can after seeing your deletion request, if it is made.

I really do love this build, you went above and beyond in creating it. Most of the few models that exist don't have a cowling or pylon, which I think adds so much to the aesthetics and feeling (well, looking at it on screen feeling). I'm still surprised or shocked you can't get a proper model of one (I really wanted one of the iconic GE-90) as I just love Turbofans for some reason. They just get me going, always. And since no one offers it, I decided I'd slowly learn the things necessary to build one myself based on yours and your inspiration sources. At current rate it will be a long while. I've been getting better with electronics, but got slowed down by my own recent moves. Next step is a 3d printer, so full disclosure, I applied for a 3d printer (reason for new comment was I had to find your original video to credit) with stated goal of printing a model similar to yours. Even if I don't get to make one as great as yours I'm just happy someone did it and took the effort and time to record it and share it with the world. Good luck with your move, hope it goes smoothly, but box that project well, it's super unique and something that should bring you great pride.

You can find the tweets by searching at Morbo on Twitter, but be careful when searching. I wanted the Futurama name MorboTheAnnihilator, but it was too long, and now I have yet to figure out if Morbo means something in another language or Twitter is just deranged.

Hi Rick, it was nice to get away from the pressure of building my designs and just going with somebodies else's design. So much fun and I think it shows I the video. Thank you.

Merci beaucoup pour les gentils mots et d'avoir pris le temps de passer et de commenter! Cordialement Karl

Hi Kenny, great to hear from you. I enjoyed building this model, it took me back to my apprenticeship training days of looking at cutaway gas turbines.

Hi Kenny, great to hear from you. I enjoyed building this model, it took me back to my apprenticeship training days of looking at cutaway gas turbines.

Love it! We grind and mill turbine blades and vanes where I work. (a lot of P&W, Vericore and Honeywell parts)

Hi Jose, I use the Creality CR10 V3 as my filament printer and highly recommend it! Thank you and kind regards Karl

I was also waiting for the "working" part..

After seeing the rocket engines that are now 3d printed metal, I do wonder if this is possible. But I'd need a few more people watching my vids, before that becomes a reality!

@@helimech8152 this is my first day.

@@helimech8152 dude thats a must, seeing that work would be phenomenal

​@@helimech8152 Put the "Thanks" button so that people can donate.

Hi Tom, hello from Brunei, thank you for taking the time to comment and the kind words are much appreciated. Put a smile on my face. Thank you and kind regards Karl

Its a great build and certainly a bit of a puzzle if you dont read the instructions! lol

This was done on a CR10, id love to see the quality on newer machines like the Bambu! Thank you for the kind words.

Hello, ill leave that job to the professionals like Rolls Royce & General Electric! It does make for a great show piece though. Kind Regards Karl

Hi Zach. You are so welcome and thank you for the kind words. Best regards Karl

The Trent 900 that this 3D printed model depicts is one of those. There are only three “bolted” attachment points to the wing. There is a forth vertical pin from the wing that goes into the pylon but only constrains the thrust of the engine. It supports no weight whatsoever and does not need to be detached to remove the engine. The three bolts are also not solid connections but are actually pivot points themselves. All this is done to carefully distribute the weight, aerodynamic loads, and thrust of the engine to the wing structure without generating additional parasitic stresses. This 3D printed model has four bolt attachment points but there would be additional brackets that go between these attachment points and the three bolted connections on the wing. The socket for the vertical thrust pin is modeled in the pylon. Some builders of this 3D model have gone as far as modeling the additional brackets and basic wing structure to attach the engine model.

It still makes me smile now when I look at it. The designers did an awesome job .

Hello and thank you! Kind Regards Karl

Hello Sir, thank you for taking the time to comment and the kind words. Kind regards Karl

Hi John, That would be a dream to build an engine with one of those printers. The quality of the build would be amazing and I would love to see what sort of centrifugal loads they could withstand! Kind Regards Karl

@@helimech8152 With Graphene Nanotubes and microthermal heat transfer I think one could be designed and built in one day. Just need peramaters to input to computer design...... Nvidia has the computer to design and render anything in under 1 second...2021 is a great year

Hello and thank you! Kind Regards Karl

This was a very fun build. one of my favourites.

Hi John, that's a pretty cool idea!

I love it!

Hello, To be able to make this at home by primarily pushing a button is fantastic. 3d printers have helped produce parts i could only dream of when regarding the full sim build. Kind Regards Karl

Thank you very much! I did enjoy this build! Kind Regards Karl

Thank you very much! Next time! Kind Regards Karl

Humbled by your words, thank you! Kind regards Karl

Hi Sophoclis K, When the design was created, I wouldn't imagine there were many Resin printers available 5 years ago. If I had printed all the parts with a filament printer, I think it would have been super smooth. With a resin printer, my parts come out 0.4mm bigger in diameter. This caused friction against the filament casings. However, Chris the designer actually designed the rotors with wear rings. So as the unit was rotated more and more these wear rings bedded in and the friction reduced. I also need to replace those 3d printed bearings with new steel bearings. This should also improve the running of the unit.

@@helimech8152 My first and very brief experience with a 3D printer was with a raisin one, about 11 years ago but it was so expensive at that time, it would make it impossible to own one. I was so impressed back then, even with the simplest sample: a ball embedded in a nut with a spherical cavity, which would make it impossible to be created as two separate parts and then put them together as such. Since then, 3D printing has become much more affordable, but still what people can do with it still amazes me! That jet engine model is a marvel and I’d really like to see a video when you’ll have all the things that you mentioned sorted out!

Thank you, the designers did an awesome job on this!

@@helimech8152 They made an awesome kit! And you did a fantastic print and build of it! How much PLA / resin did the build consume?

How could would that be!

I know, the surge and compressor stall is a real pain!

If you love aviation then yes! Its truly amazing and such a fun build. Go for it!

Well that made me smile! Indeed...Cool! Kind Regards Karl

Hi Andy, this is for a sim prop. But as many others have mentioned, this would also make for a great teaching aid. Kind regards Karl

Hi Cory! This was such a fun build and i loved every moment as an aviation enthusiast!

Hello, not really. it was just the rotors to the shafts. They will come apart. (hopefully!) Kind Regards Karl

Hello, not really. it was just the rotors to the shafts. They will come apart. (hopefully!) Kind Regards Karl

Just go slow, If you go too fast they will melt together

@@helimech8152 Yeah I thought of that. Also, The problem was bent LP AFT shaft. It was wobbling. Found my Printer Nozzle assembly tilted on one side. That explains why the shaft was printed like its bent.😄

Thank you, This design belongs to Chris and Bob. They are the geniuses behind it.

Hello, The Ender 3 is too small. I have been informed that there are files included to split the design further down for the Ender 3 though. I have not looked at this option. The ender 3 Pro is an excellent printer for the price and i own 2. You can definitely build the whole engine core on the ender 3. for the larger cowling panels, I used the slighter larger CR10 v3 which has a bed size of 300mm x 300mm. If you can stretch to this printer, I would go straight for it. Its silent and works brilliantly, its like the next level up to the ender 3. Kind Regards Karl

Hello Ed, you are correct, didn't release I said that! ramblings of a man getting old.

@@helimech8152 Hahaha, its very cool anyway.

Hello MJ, Thank you very much for those words. Kind Regards Karl

I literally just made pretty much the same comment b4 reading yours def a good idea

Any time and thank you for taking the time to comment.

Hello, and I agree! Too cool for Skool!

Hi, i have 2 3d resin printers. The Creatilty LD002R wins over Elegoo mars easily in my opinion. The other ones are a wash machine and curing unit. I will certainly try to create something in the future once the throttle unit is done. Kind Regards Karl

Thank you! I think so too! lol Kind Regards from Brunei.

Thank you, the files are courtesy of the designers Bob & Chris. Kind Regards Karl

Thank you so much 😀

Hello old friend, I am well! Covid has just hit Brunei and we have entered lockdown. I have not made a video in ages because of the time involved behind the scenes creating the motorised throttle. This is now coming to an end hopefully and I will be able to concentrate on smaller and quicker projects. Kind Regards Karl

Ill Leave that to RAMY RC!

Haha! You just nailed it! The bearings are sat next to me on my desk, they arrived about two weeks ago, but I don't think I'm ready to take it back apart yet! Kind Regards Karl

This was such a long time ago, i couldn't inform you of what i used. I would guess most of the filaments would now be obsolete anyway.

@@helimech8152 I appreciate you taking the time to reply. Keep up with the good work! 👌🏼

Hi Ray, I am very much learning the video front. There really is so much to learn and i now appreciate people who do this for a living!

Hi Matt, The design was awesome and I agree that the end product looks fantastic! The creators did an amazing job. Thank you. Karl

Hello, and yes that happened! The thing I was most afraid of. But it all worked out in the end. Kind Regards Karl

Thanks Steve!

Thank you too! & kind regards Karl

Thank You

Thank You!

BTW would this set be printable on the latest CR10?

Hello Joeri, If you can i would get hold of a CR10. That would be much cheaper than getting the parts printed! and yes it will all fit as that is the printer i used. Kind regards Karl

Thank you!

Thank You from Brunei! Karl

Hello, I'm not sure of the actual model, I think it may be an amalgamation of engines to show the principal.

Olá, o design inclui a adição do motor elétrico, só não mostrei isso neste vídeo. Atenciosamente Karl

@@helimech8152 Vamos ver no próximo vídeo os resultados então. Thankyou

If it did, id be a very rich man! Well probably not actually, the designers Bob and chris would be!

Thank you! Cheers!

Hi Bill, I hope this finds you well! Thank you as always. Kind Regards Karl

Hi Barrie, I now need to return and get finished with my latest build for the 737 sim. This was just a break, but someone has now sent me a turbo prop to print! I look forward to that one.

Thank you so much 😀

I have to admit, until this comment I didn't know about that channel. I do now! Kind Regards Karl

Hi Philip, Thank for the awesome comment. Kind Regards Karl
