No, a USB flash drive is not included by default.

You can still start prints normally without a USB drive, as the printer has built-in storage for executing print files.

However, the absence of a USB drive affects the following features:

Time-lapse recording and photo capture cannot be enabled.

Printing via LAN is not possible.

Sending print files to the printer for storage through the project interface is disabled.

Log file export is not supported.

USB Requirements:

USB 2.0 or higher protocol

Minimum write speed: over 10 MB/s

Only one USB drive is supported; USB hubs or multiple drives are not compatible.
