Sierpiński Triangular Bipyramid Fractal - Level 3 (Vase Mode)

I designed this level 3 self-similar triangular bipyramid fractal in CAD to be printed in vase mode.

The model can be printed once as a single pyramid, or in two halves and assembled into a complete structure.

I've included a 3MF for a plate with two halves. Print both halves and glue them together to capture the full self-similar fractal design.

Don't forget to check out higher levels of this fractal available on my page  now. You can find level 6 here:

Print Settings:

This model was created and optimized for FDM printers with vase mode enabled. For best results, use spiral vase mode with the smooth spiral option unchecked in your slicer settings. If you don’t see the smooth spiral checkbox in your slicer, no worries—just be sure to use Spiralize Outer Contour (or a similarly named option in your slicer, such as spiral/vase mode).

Ensure your slice gap closing radius is set to 0, as this is critical for proper vase mode printing. Without this setting, the slicer may close gaps that are necessary for the model to slice and print correctly.

Enable the “Skirt” option in your slicer to maintain consistent nozzle pressure from the start. Without it, the first layer’s corners may appear deformed due to unprimed nozzle pressure.

If you want to print both halves at once like I've set up in the included 3MF, Enable "Print by Object" to print two objects on one plate in vase mode. Just make sure to leave enough space between them for extruder clearance!

If you find yourself having trouble, please reach out. I’d be happy to hear from you!

Have fun! 🥳
