Uploading G-code Files from Your Slicer

G-code files contain embedded metadata from your slicer — filament type, weight, print time, and more. Uploading a G-code file gives you the most accurate cost calculation possible.

Supported Slicers

Printforge reads comment-line metadata from these slicers:

• Bambu Studio / OrcaSlicer — filament type, weight, print time, layer height
• PrusaSlicer — filament type, used weight, estimated time
• Cura (UltiMaker) — material type, filament weight, time estimate

What Gets Auto-Filled

When you upload a G-code file, the calculator automatically populates:

• Material weight — exact filament usage in grams
• Print time — estimated duration from the slicer
• Material type — PLA, PETG, ABS, etc. (auto-matches to your library)

If the G-code's material type matches a material in your library, it's selected automatically. Otherwise, you can pick the correct one manually.

Uploading

On the Calculator page, use the upload panel and select your .gcode file. Like STL uploads, the file is parsed in your browser — no server upload needed. The parser reads only comment lines (starting with ;) and ignores the actual movement commands.

G-code vs STL

G-code gives you precise numbers because the slicer has already computed exact filament usage and timing. STL estimates are based on volume and density, which are approximate. Use G-code for final quotes and STL for quick estimates.
