How to Convert Multiple AI Files to STL?
1. Download and Install reaConverter
reaConverter is a standalone Windows app — download, install, and start converting AI files in under two minutes.
2. Load your AI files
Add AI files to reaConverter. One file or a thousand, the process is the same. Everything runs locally on your machine.
You can drag-and-drop files, browse to a folder, or add entire directory trees including subfolders.

3. Select STL as output format
Pick STL as the output format. Set the destination folder and optionally configure resolution, quality, or file naming.

4. Start AI to STL conversion
Click the Convert button to start. reaConverter will process all your files with the settings you selected.

When finished, your new .stl files will be waiting in the destination folder.
AI to STL: what carries over and what does not
One AI file can hold several pages or frames, while STL holds one image each. reaConverter writes a separate output file per page and numbers them, so a single input can produce a whole folder of results.
