Formlabs regularly releases updated firmware to fix bugs and improve functionality. Check your printer's firmware to ensure you're always up to date.

As long as a Formlabs printer has an active internet connection, it receives notification prompts about new firmware updates becoming available upon their release. Accept the prompts and tap Install on the Firmware Update screen to stay up to date.

To check a printer’s current firmware version:
