Iron graphics on the top layer (3D printing post-processing script).
- Download the
selective-iron-postprocess.pyscript - Note its full file path
- In PrusaSlicer, go to Print Settings > Output options > Post-processing scripts
- Paste the absolute path to the script
Design your part with a 1-layer-tall extrusion on the topmost surface representing the graphics you want ironed.
- Enable Ironing for the Topmost surface only
- Set ironing Flow rate to 0%
Slice and print. Note that post-processing effects won't show in the slicer preview.
The script:
- Extracts all ironing move blocks from the top layer
- Automatically detects layer height and Z position
- Converts flat travel moves into proper retract/lift/travel/lower sequences
- Positions ironing moves at the optimal height for surface polishing
- Replaces the entire top layer with only the ironing passes
- Python 3.6 or later
