Exporting Models for Print Hive

Print Hive uses .gcode.3mf files that bundle your sliced G-code with 3MF metadata, thumbnails, and plate information. This guide shows you how to export these files from popular slicers.

Bambu Studio

Bambu Studio makes it easy to export plate-ready .gcode.3mf files:

  1. Prepare your model: Import your 3D model, arrange it on the build plate, and configure your print settings (layer height, supports, filament, etc.).
  2. Slice: Click the "Slice plate" button to generate G-code for your configuration.
  3. Export: After slicing completes, click the "Export" button in the bottom toolbar.
  4. Choose format: Select "Export plate sliced file" from the export options.
  5. Save as .gcode.3mf: Bambu Studio will automatically save the file with the .gcode.3mf extension, which includes:
    • Your sliced G-code
    • Plate layout and settings
    • Preview thumbnails
    • Filament colors and material info

Orca Slicer

Orca Slicer, a popular fork of Bambu Studio, uses a similar export process:

  1. Set up your print: Load your model, configure supports, infill, and other print parameters.
  2. Slice the plate: Click "Slice" to generate the G-code based on your settings.
  3. Export sliced file: After slicing, find the "Export" menu (usually in the bottom-right or top menu bar).
  4. Select .gcode.3mf format: Choose "Export sliced file" or "Export plate sliced file". Ensure the format is set to .gcode.3mf.
  5. Save to disk: The exported file will contain all plate data, thumbnails, and settings needed for Print Hive.

Why .gcode.3mf?

The .gcode.3mf format offers several advantages:

  • Complete package: Bundles your sliced G-code with the original 3MF container, preserving all metadata.
  • Visual previews: Print Hive can extract and display plate thumbnails automatically.
  • Plate awareness: Multi-plate projects maintain their structure and settings.
  • Reliable reprints: You can re-send the exact same job to printers without re-slicing.
  • Metadata extraction: Print Hive automatically reads filament colors, print time estimates, and material requirements.

File Size Considerations

.gcode.3mf files can be large (typically 10–100 MB depending on model complexity). Print Hive supports files up to 500 MB. For very large multi-plate projects, consider:

  • Splitting plates into separate files
  • Reducing thumbnail resolution in slicer settings (if needed)
  • Compressing complex support structures where possible

Troubleshooting

File won't upload

  • Verify the file extension is exactly .gcode.3mf (not .3mf or .gcode alone)
  • Check that the file size is under 500 MB
  • Ensure your slicer exported the "sliced file" not just the model

Missing thumbnails or metadata

  • Make sure you sliced the model before exporting (not just the raw 3MF)
  • Check slicer settings to ensure thumbnails are enabled during export
  • Verify you selected "Export plate sliced file" not "Export 3MF"

Next Steps

Once you've exported your .gcode.3mf file, you can upload it to Print Hive:

  • From the Models page, create a new model or open an existing one
  • Drag and drop your .gcode.3mf file into the upload area
  • Print Hive will process the file and extract thumbnails and metadata
  • Once processed, you can send the model to any connected printer
