Included in PrintBusters Toolkit for Fusion 360

Batch Export STL

Export every body in your design to its own STL file. No more right-clicking one at a time.

What it does

If your design has multiple bodies, exporting them individually gets tedious fast. This tool grabs all of them (or just the ones you pick) and saves each as a separate STL, named after the body.

You choose the mesh quality, pick a folder, and it handles the rest.

Where to find it

Design → Modify → PrintBusters Toolkit → Batch Export STL

How to use it

  1. Open your design in Fusion 360
  2. Go to Modify → PrintBusters Toolkit → Batch Export STL
  3. A dialog appears with three dropdowns: export scope, mesh quality, and file format
  4. Click OK, then pick an output folder
  5. Done - each body lands in the folder as its own .stl file

Export options

Export scope

  • All visible bodies - exports everything you can see, skips hidden bodies
  • Selected bodies only - exports only what you've selected in the browser or canvas
  • All bodies (including hidden) - exports everything in the design

Mesh quality

  • Low - fast export, coarser triangles. Good for quick test prints or large flat parts.
  • Medium - balanced detail and file size.
  • High (default) - finer mesh with more triangles. Recommended for most prints.
  • Ultra - custom mesh settings with very tight surface deviation (0.005 mm). Best for parts with small holes, cylinders, or curved features that need smooth circles.

File format

  • Binary (default) - smaller files, supported by all slicers
  • ASCII - human-readable plain text, useful for inspecting or editing the mesh manually

How files are named

  • Each file is named after its body (e.g. Top Cover.stl)
  • Components in assemblies include the full path (e.g. Frame_Bracket_Body1.stl)
  • If a file already exists, a number is appended to avoid overwriting

Good to know

  • Your design is never modified - the tool only reads geometry.
  • A progress bar shows export status with a cancel button if you change your mind.
  • Works with assemblies, nested components, and multi-body parts.

Troubleshooting

Nothing was exported

  • Make sure at least one body is visible or selected
  • Check that you have a design open (not the Data Panel)

File names look wrong

  • Rename bodies in the Fusion browser before exporting - the tool uses whatever names you set
