Check the logs.  Most likely it uses a port that you're not allowing or is triggering UTM features such as anti-virus.  You may need to put the PC, printer, or both in a clean rule that has no UTM (or certain parts disabled).  The logs *should* indicate what it doesn't like, but you may have to experiment.

Check your FortiGate firewall rules—it's likely blocking the printer's ports or protocols. Adjust the settings to allow 3D printer file transfers...
