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??
Because of this video, I ended up printing one as well. Took over a month with my single printer and printing my last chevron thrust reverser piece as I type this. Less than 24 hours on print left. Thanks for the awesome video Karl!
This is still a dream of mine to build this model. Thanks again for building on others work, building it, and putting it together. I love turbofans and don't understand why stuff like this isn't available.
I think my original reply was auto deleted by UA-cam, 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.
Wow. Superb job there ! Reminds me of Happy days in Derby during my RR apprenticeship many moons ago. Thanks so much for sharing a great project ! ... 🇬🇧
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.
@@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.
I love the colors you used for the casing body and stators. I ordered Metallic PLA to try to match all the colors you're using and I'm printing the pieces now. The Bamboo P1P is churning these prints out fast. This video is very inspirational. Great job!
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!
In the early 90s, the traveling Smithsonian exhibit -- you know, the Hope diamond, Lincoln´s 10-gallon hat, Dorothy´s shoes, and a Moon Buggy, came to town, which I was happy to visit. What _really_ blew my mind, though, was a slowing rotating _perfect_ quarter scale model of a commercial turbofan engine at the egress of the exhibit. I have come to realize this as one of the first examples of additive construction. The model was even sized to incorporate thousands of titanium bolts -- a quarter the size as those actually used. Wonderful!
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.
DUDE, THE VIDEO AND ITS CONTENT ARE VERY GOOD. I've watched many videos since UA-cam was launched, but this was the best of the thousands of videos I've watched. Thank you very much. Ankara and Ferhat Sogukkuyu
Now you need to print another one, then attach them to either side of the sim. Or even better hook them up to the sim so when you do an engine start they spin that way you can confirm engine start.
Absolutely Awesome Karl! 3D printers are becoming one of the most amazing tools. You think of something, and it becomes real! I thoroughly enjoy your video's mate!
Truly, it is an excellent build. I have built and still working out some details. I created a detailed accessory package and a swiveling undershelf mount along with 3d lights and a faster 2000 rpm motor. I love this Trent 900 design. Pay the $15 to WileyRC and get the functional reversethrusters. It's amazing!
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 Karl! I’ve been just lurking around for many many episodes. I enjoy them not only because of the stupendous engineering and handicraft but because you have a wonderful and engaging personality and a permanent smile! I enjoyed this build tremendously and I am fighting the urge to build one myself. Please keep doing what you do! All the best from Argentina.
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
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!
That look gorgeous. Love every detail of it. Now I wonder what would it take to build every single part of a real engine and assembling it to precision.
Have you thought of using 3dGloop instead of CA glue. It’s a chemical weld rather than adhesion. Particularly when sanding produces a better surface of the joint since it’s all PLA (Note fumes aren’t awesome for you)
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
There is stool to scrape off edges, it turns to follow contour. Also magnetic extendable tool for screws. Put graphite between rotating parts and casing so spin easier and not heat up as much.
Haha, that's sensational, Karl! Thumbs up! Next you should print throttle quadrant of same scale and connect em together! :D PS. Attaching vacuum cleaner's motor at the end will give almost real sound as well! :))) All the best, Phil.
Cool idea! I need to strengthen the large turbine blades first. The stress of more rotational force and i can see it ripping itself apart. However, since building this, many other 3d printed engines have now popped up on my radar that have designed with extra speed in mind.
It's been absolutely fascinating and educational seeing you put this model turbofan jet engine together from scratch (so to speak). It's given me a much greater insight into it's inner workings aided by your jolly enthusiasm.
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

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.

Hello Carl. I was only thinking about you the other day whilst I was driving to work.. I was thinking I've not see you on UA-cam for a hit hope you are keeping well 🙂
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
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!
That's so neat ^_^ something about engines is just fascinating! I've been looking for my next big 3D printing project to do also! Last summer my big build was the Subaru EJ20 boxer engine, and it was a real journey. It really tested me and my DIY 3d printer just as much. This model is definitely on the tentative list :-D
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
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
First of all... what a fantastic project!! It's nice to see you assembling these components! I have downloaded the 160+ files but as a 3D layman (utter noob) I have no 3D printer. Are those files sufficient to be sent off to a printing company and have them deliver the non assembled set? Are there any companies who you could recommend? What price is to be expected for this huge printing job? With thanks and kind regards! Keep those great videos coming!!!
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
So I started my build yesterday. Bearings are in the works as we speak. Question: what filament did you use for the trim ring on the front of the intake? If not, did you cover it? Im working on the Nozzle Assembly now, should be finished today.
Hi at the ripe old age of 76 I am thinking of buying a 3D printer to makes parts for a 737 sim, but which one to buy on a limited budget would you think that the ENDER 3 PRO would be up to the job, any advise would be appreciated, many thanks
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
This awesome piece is on my build list. But question for you, what is that blue work surface that you're working on? Those compartments look ideal for holding small parts.
Hey, thanks for printing this, and thanks for the shout-out! The nacelle cowlings really do take the design up a notch, don't they?

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
Amazing model of a turbine!! I was wondering if teflon spray on the parts that still have some friction, would make it run smoother.
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!
That's so neat ^_^ something about engines is just fascinating! I've been looking for my next big 3D printing project to do also! Last summer my big build was the Subaru EJ20 boxer engine, and it was a real journey. It really tested me and my DIY 3d printer just as much. This model is definitely on the tentative list :-D
I can't recommend this enough. It looks stunning on the shelf, and even better fun building it.
Wow, that is superb!
Thank you! It's a cool bit of kit!
That's so cool.
Karl, this is amazing. Can you do a video describing your SLA printer setup as I see you have a few machines there in the corner.
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
That is so bloody cool. I'm definitely going to print this :)
Hello! I can't recommend this design enough!
Awesome can't wait to see it work with a motor
Hi Richard, I'm currently looking for speed controller and motor that will achieve at 8000 rpm
Awesome can't wait to see it running again.
OMG, It is amazing. Keep it up.
Thank You! Kind Regards Karl
imagine you glued everything got half way and realized you made a mistake lol X.X
Hello, and yes that happened! The thing I was most afraid of. But it all worked out in the end. Kind Regards Karl
You should add a small accessory gearbox with a little dynamo that generates power for the red LED.
Hi John, that's a pretty cool idea!
Lot of fun watching this go together, but something tells me you did not take it apart later to put in the proper bearings.
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
First of all... what a fantastic project!! It's nice to see you assembling these components!
I have downloaded the 160+ files but as a 3D layman (utter noob) I have no 3D printer.
Are those files sufficient to be sent off to a printing company and have them deliver the non assembled set?
Are there any companies who you could recommend? What price is to be expected for this huge printing job?
With thanks and kind regards!
Keep those great videos coming!!!
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
Super cool!
So awesome
Superb!!!
You will have a 737 printed next karl!!! Brillant.
That was actually what I was looking for. I wanted a display model.in the background. But I couldn't find one. Kind regards karl
Wonderful work.
Thank you so much 😀
Holy Batman!!!
What would be really great is turn it into a desktop fan, that you could use
I literally just made pretty much the same comment b4 reading yours def a good idea
Enjoyed it!
Thank You.
Great quality
Thank you!
Looks great. A little error is the Stators shouldn't spin.
Hello Ed, you are correct, didn't release I said that! ramblings of a man getting old.
@@helimech8152 Hahaha, its very cool anyway.
wow~ thank you
Hey Karl, Would you be able to list out the exact colors and types of filament you used
you super-glued something that you should replace later :P
Hello, not really. it was just the rotors to the shafts. They will come apart. (hopefully!) Kind Regards Karl

Good job!
Thanks!
So I started my build yesterday. Bearings are in the works as we speak. Question: what filament did you use for the trim ring on the front of the intake? If not, did you cover it? Im working on the Nozzle Assembly now, should be finished today.
good job👍
Thanks for the visit and taking the time to comment. Kind Regards Karl
Cool! I like it.
Hi at the ripe old age of 76 I am thinking of buying a 3D printer to makes parts for a 737 sim, but which one to buy on a limited budget would you think that the ENDER 3 PRO would be up to the job, any advise would be appreciated, many thanks
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
nice build… looks like a Rolls Royce engine due to the sharp tip of the spinner core
Hello, I'm not sure of the actual model, I think it may be an amalgamation of engines to show the principal.
This awesome piece is on my build list. But question for you, what is that blue work surface that you're working on? Those compartments look ideal for holding small parts.
Its an amazon Blue work mat silicon. Just type that in and you will see hundreds!
And also are these machines capable of making anything no matter how difficult and complex it is
