Supports enabled (support_enabled)

Supports enabled is on or off. Enable support generation.

What does each slicer call it?

Five slicers, five spellings of one setting. The scope column is which preset the key belongs to, which is what decides whether changing it follows the printer, the filament, or the print profile.

Slicer Key Scope
PrusaSlicer support_material process
Bambu Studio enable_support process
OrcaSlicer enable_support process
Cura support_enable process
Creality Print enable_support process

Where does it live in the file?

All five slicers file this under the process preset, so its value follows the print profile rather than the model. A .3mf is a zip, so unzip it and search for support_material, enable_support and support_enable, or open the file in preslice and read the Raw tab, which searches every member at once.

Four of the five slicers write their settings into a sidecar part beside the geometry. Cura writes them into the model XML itself, so there is no config part to open.

Slicer Part Format
PrusaSlicer Metadata/Slic3r_PE.config INI, one key = value per line
Bambu Studio Metadata/project_settings.config JSON, one flat object
OrcaSlicer Metadata/project_settings.config JSON, one flat object
Cura 3D/3dmodel.model XML metadata inside the model part, under a cura namespace
Creality Print Metadata/project_settings.config JSON, one flat object

What values are valid?

Each slicer declares its own type, default, and bounds for its key. They do not always agree, and where they disagree the file is still valid in both: the slicer that wrote it is the one that enforced its own rule.

Slicer Type Unit Default Range
PrusaSlicer float not declared 1 not declared
Bambu Studio float not declared 0 not declared
OrcaSlicer float not declared 0 not declared
Cura bool not declared on not declared
Creality Print float not declared 0 not declared

PrusaSlicer, Bambu Studio, OrcaSlicer, Cura and Creality Print declare no range for this key, so nothing in the file bounds it.

This value is not a number, so PrusaSlicer, Bambu Studio, OrcaSlicer, Cura and Creality Print declare no unit for it.

The slicers disagree on the type: Cura as bool, PrusaSlicer, Bambu Studio, OrcaSlicer and Creality Print as float. preslice reads all of them.

Every type, default, and bound above is read from the slicer's own field definitions rather than from measurement: PrusaSlicer's PrintConfig.cpp, Bambu Studio's PrintConfig.cpp, OrcaSlicer's PrintConfig.cpp, Cura's fdmprinter.def.json and Creality Print's PrintConfig.cpp.

Can I read it from my own file?

Yes, without installing a slicer. Open preslice and drop a .3mf on the page. It unzips and parses the file in your browser, and shows supports enabled under its own name alongside the rest of the print settings. The file never leaves your machine, and nothing uploads.
