Turn 3D models into printer instructions called G-code with OrcaSlicer. The skill selects existing printer and material presets, slices the model, and checks dimensions and output settings before handing over the files.
Slice 3D models into printer-ready G-code with OrcaSlicer, the open-source slicer with built-in profiles for most FDM printers (Prusa, Bambu Lab, Creality, Voron and more). Use when the user wants an `.stl`, `.3mf` or `.obj` model sliced for their printer, as a sliced `.gcode.3mf` or plain `.gcode`, headless with OrcaSlicer's command line or by opening the model in OrcaSlicer. Never contacts a printer.
Review the instructions the agent will receive before you install.
Provenance: maintained in earthtojake/text-to-cad. Use the installed local skill files as the runtime source of truth; the repository link is only for provenance and release review.
Slice with OrcaSlicer, headless (below) or by opening the model in the
OrcaSlicer app for the user. The agent never contacts a printer: for a Bambu
Lab printer, hand the result to $bambu-labs; for any other printer, give the
user the .gcode.
brew install --cask orcaslicer. The command line is
/Applications/OrcaSlicer.app/Contents/MacOS/OrcaSlicer.orca-slicer; on Linux, run it from the AppImage or Flatpak.Below, <orca> is that command.
OrcaSlicer's command line (https://www.orcaslicer.com/wiki/cli/cli_mode) needs
complete presets: it doesn't fill in a preset's parent settings, and it slices
only with a process whose compatible printers name the printer.
scripts/orca_presets.py (Python 3, no dependencies) writes them from
OrcaSlicer's presets, searching the user's own first, then OrcaSlicer's
built-in profiles.
Find the user's printer, process and filament presets. Prefer the presets the user prints with; never invent one, since a wrong bed size or temperature can damage the printer.
python scripts/orca_presets.py --list machine --match "MK4S"
python scripts/orca_presets.py --list process --match "@MK4S 0.4"
python scripts/orca_presets.py --list filament --match "PLA @MK4S"
Write the complete presets:
python scripts/orca_presets.py --printer "Prusa MK4S 0.4 nozzle" \
--process "0.20mm SPEED @MK4S 0.4" --filament "Prusa Generic PLA @MK4S" \
--out presets
Slice. Give --outputdir an absolute path:
<orca> model.stl \
--load-settings "presets/process.json;presets/printer.json" \
--load-filaments presets/filament-1.json \
--arrange 1 --slice 0 \
--outputdir /absolute/path/to/out --export-3mf model.gcode.3mf
This writes plate_1.gcode, the plain G-code, and model.gcode.3mf, the
sliced 3MF, into that folder. The command line reads .stl,
.3mf, .obj and .amf; export STEP to STL or 3MF with $cad first.
Override one setting with --<setting>=<value>, using the setting's key
with hyphens for underscores, such as --layer-height=0.16.
When the user would rather pick presets and slice themselves, or no preset can
be found, open the model in the app: open -a OrcaSlicer model.stl on macOS,
Start-Process model.stl on Windows when OrcaSlicer opens that file type, or
orca-slicer model.stl on Linux. The app also reads STEP.
<orca> model.stl --info prints the model's size; it has to fit the bed.
Check the slice's settings, which OrcaSlicer writes at the end of the G-code:
grep -E '^; (printer_model|nozzle_diameter|filament_type|nozzle_temperature|hot_plate_temp|bed_temperature) =|printing time' out/plate_1.gcode
Confirm they match the user's printer and material before anyone prints it.

Prepare files for printing on Bambu Lab printers by opening sliced files in Bambu Connect or unsliced models in Bambu Studio. The user selects the printer, checks the setup, and starts printing in the app.
Create and edit 3D parts and assemblies with adjustable dimensions using cadgen. Export STEP, STL, 3MF, or GLB files, inspect geometry, and open existing models in CAD Viewer for visual review.
Check mesh files for 3D printing by measuring geometry and comparing it with process-specific design limits. Get findings on wall thickness, overhangs, and supports, plus build orientation options and concrete redesign guidance.
Review part designs for sheet metal, CNC machining, or injection molding. Compare geometry measurements with applicable supplier or tooling limits, then document manufacturing concerns, suggested changes, and checks that still need evidence.
Create and update 2D DXF drawings from written requirements or CAD geometry using Python and build123d. Prepare cutting profiles and marking layers, check for open contours and duplicate geometry, and review drawings in CAD Viewer.
Create a manufacturing drawing PDF from a part’s 3D geometry, with projected views, measured dimensions, hole callouts, and a title block. Rerun the drawing script after model changes to update the sheet.
