Watertight Spiral Print Presets

These print profiles* make for strong, gorgeous, seamless, watertight** prints in Spiral Vase Mode. (Non-spiral variants are coming soon.) Not the usual flimsy threads of Josef Průša's spiral print profiles. Notable characteristics of my spiral profiles are relatively tall and exceptionally wide perimeter extrusions, extra bottom layers, and greater overlap of perimeters and infill. I provide configurations for all nozzle sizes from 0.35 to 2.0 mm.

* Or “presets” as the kids are now calling them.

** Without post-processing, I aim for IP65-rated protection.

Instructions

Put the .ini files in the directory where you keep your print profiles.

• In Linux: ~/.config/PrusaSlicer/print
• In Windows: C:\Users\[name]\AppData\Roaming\PrusaSlicer\print

A small bottom section of a pot is included as a benchmark test model.

Troubleshooting

If you do encounter any leaks through the bottom of the test model, then you probably need to increase your printer's flow-rate multiplier. (Note that, in the latest experimental profiles, this is forced to 106% through gcode substitution.)

If you encounter leaks just at the bottom edges, then you probably need more overlap between the perimeter and the infill.

If you encounter leaks through the perimeters, then you probably need to print them more slowly or with heavier fan use.

Notes

The word on the street is that polypropylene is one of the best materials for watertight prints.
