It will inspire me to design more exciting aircrafts.

This 3D model is a highly detailed recreation of the B-2 Stealth bomber, designed with accuracy, clean geometry, and 3D-printability in mind. The goal of this project was to capture the iconic flying-wing shape while keeping the model suitable for both display and printing.

Accurate flying-wing proportions Clean, optimized mesh, Designed for display or 3D printing. This model is ideal for aviation enthusiasts, collectors, and anyone interested in stealth aircraft design. Whether you’re printing it or using it for visualization, this B-2 Spirit captures the unique presence of one of the most iconic aircraft ever built.

Print Setting:

Printer Type: FDM (Resin printing also supported with minor adjustments)

Sorry for this. Try to print it in slower speed. It's a difficult project to print. But thankyou for trying.

@Rhodehouse

I will try again in a slower speed. if it turns out better I will change my rating. thanks for the advise

@madizmo

exact same as how mine turned out

@user_3053227993

This design is very bad and impossible to print. Author made this model as shell body with many flat angle surface's. Therefore it is impossible to print it with supports which would need to be embedded inside the model. All bobmbay doors are also printed in mid air so regardless of printing speed and settings spaghetti will appear. To author: sory mate but this is not how FDM model's need to be designed. It is not about easy or hard printing settings, it is about following basic modeling rules which you broke. Therefore many people will complain that despite their efforts and dozens of hours spend on slow prints setting this model will end up as spaghetti.

Check out the one I did!

@SNDMKL

Well-detailed design. However, I'm having trouble with the landing gear and bomb doors, where the spaghetti begins. Three attempts with different profiles, including the one you recommended, have yielded the same results.

Share me your printer specifications. I'll share you the 3mf file for it.

You have created a beautiful and detailed model, but I am having trouble with the flaps on the underside of the main body and the control surfaces on the wings. Can you create a file where the flaps on the main body and the control surfaces are separate?

Hii, please watch the last half of the video. Can you please elaborate what is the exact issue you are fasing?

@user_2903430157

Replying to @umar46242 :

My prints fail as soon as I print the second control surface on the wings, as it always falls off. Could you create a file where the control surfaces and the wings are separate? I've managed to fix the problem with the main body.

@imahobo

yo this is the best thing ever

@umar46242

Thanks bro

@user_2228731735

Unfortunately, I also constantly have failed prints... can people who have managed this please report? How did you do it? Which printer? Which filament? Which speeds?
