Description

Hello Makerworld community !

For my first design and contest on this platform I make a rocket thruster inspired from the work of Leap71 company. This firm is a pioneer in Computational Engineering which can generate parts, structures or entire machine with an open-source software which translate human engineering knowledge into algorithms.

For more information on this company : https://leap71.com/

I redesign one of their AI generated rocket engines. I simplified and sized it to print it on a Bambulab 256x256x256mm bedding. All input/output ports communicate with real ducts and tubes (without the 120° cut).

Here is the parts of the model :

Printing Material:

I printed the model using PLA

- PLA Silk Copper

- PLA Matte Ash Grey

- PLA Basic black

Bill of Materials

I am currently using it as a fixing

- 4x Screws M8*1.25

- 2x Nuts M8*1.25

Next features :

Add lock pins instead of M8 bolds
Develop an educational model with different colour parts to understand which input-output communicate with

I've wanted to print this one for a while, but other stuff seemed to get in the way, well not anymore! Just finished and really like the results, Thank You for sharing.

@CataPank

Thank you for your feedback. The color scheme is great. I'm glad you like my model and that the result meets your expectations. Thanks again

is there a full version? I’m am currently working on making a rocket engine for a project of mine. found this a thought about experimenting with it. I love all of the detail that was put in to this file. I am planing on printing this out of metal for my project. if anyone knows of another full model like this I would love to know about it! but this is boost worthy!

how much does this work?

@CataPank

Replying to @atlasdunn10 :

Hello, First of all, thank you for your interest in my project. It's great to see enthusiasts like you. I designed this engine by greatly inspiring from Leap71 company work. I didn't do any heat exchange or pressure resistance calculations. However, in my complete model, all the channels actually communicate. I'd like to warn you that nothing is dimensioned, it's just an esthetic model. As for selling it, I haven't even considered it, to be honest. This design represents approximately 10-12 hours of work. I look forward to hearing from you in private message.

I will definitely let you know if it will work out for my project!

I'm looking forward to sharing this with my rocketry students. I wasn't aware of the work Leap71 was doing until I stumbled upon this model. Now I'm trying to learn how to incorporate computational engineering into my curriculum. Thank you!

could you please explain how you modeled all of the cooling channels? what software was used to make this?

The designer has replied

@CataPank

Hi ! I'm using Fusion 360 (not the optimal software but it's okay). To make channels, you have to create the shape of a sort of propeller in surface. For this you make two springs of a diameter of 1mm with needed diameters and pitch. Then extract the two path in a 3D Sketch and link it in a surface. You make the surface thick with the needed thickness and subtract the shape of your object. Now you got one channel. You can replicate it and subtract it from your principal body with booleans functions. I put pictures of the steps to be a bit more clear. Hope it can help you !

wow that looks sick. you rly should be on first place for this!

@ecnalzaho

Look's great, Can't wait to put this to the test.

The designer has replied

@CataPank

Thank you for your comment ! I'm satisfied of this design. If you have issues in the assembly for exemple, do not hesitate to give me a feedback. I will try to optimize adjustments on the print.

@Squishie

is the full model going to be published?

The designer has replied

@CataPank

Hello, The principle of this model is to have a cutaway view of the inside of a rocket engine. I could make a complete model intended to be printed with transparent filament, but it remains an aesthetic model, not calculated and not functional. Thank you for your interest in my work. Happy printing!

@s.toni

i think you have to be on 1. place. You literally built an jet engine

@CataPank

Thank you very much, your comment touches me. I'm already happy with this top 10 for my first challenge. I'm going to work on another competition to see if I can do better ! See you soon
