## Summary
The Fire Rescue Service of the Capital City of Prague has integrated additive manufacturing into its emergency response operations. Using the Prusa CORE One L, firefighters are producing custom mounts, tool organizers, and replacement components for fire engines and specialized rescue gear.

This implementation addresses both logistical and security requirements for a state agency. By printing parts in-house, the service reduces replacement costs for specialized components by up to 95% and ensures compliance with National Cyber and Information Security Agency (NÚKIB) regulations through air-gapped hardware operations.

## Technical implementation and security compliance
- **Hardware Platform:** The service utilizes the Prusa CORE One L, an enclosed, temperature-controlled printer capable of processing high-performance materials without warping.
- **Cybersecurity Protocol:** To comply with NÚKIB regulations, the printers operate in a 100% offline, air-gapped configuration, utilizing physical USB drives or secure local networks via PrusaLink for file transfers.
- **Material Application:** Printed components are tested for extreme heat and flame resistance in Flashover Container facilities, and are often printed in high-visibility orange to ensure visibility in dark vehicle compartments.
- **Operational Workflow:** The station maintains a rotation of 67 firefighters across three 24-hour shifts, with one trained operator per shift dedicated to managing print jobs and minimizing material waste.

## Why it matters
This case study demonstrates how air-gapped, locally manufactured hardware can meet the stringent cybersecurity requirements of critical state infrastructure. It also highlights the utility of sharing open-source digital models via platforms like Printables.com to improve regional emergency response capabilities.
