Hardware-level air-gapNo cloud. No telemetry.TAA and NDAA compliant
Your 3D printer might be the weakest link in your cyber security
Prusa 3D printers for critical infrastructure are the secure option.
World leaders in innovation trust Prusa
Designed and manufactured in the EU and USA. Air-gapped by hardware, not by a software switch.
Secure from from CAD to printed part
True security is a governed workflow, not just an offline printer. The attack surface is minimised across the entire data lifecycle. Isolation is physical, not a menu toggle.
Open, auditable software
PrusaSlicer is open-source and runs on your own workstation. No cloud account, no subscription, no telemetry calling home.
Zero residual data
No internal mass storage. Volatile memory, including SRAM used for print buffering, is wiped by a power cycle.
No wireless radios
CI electronics are custom-made with no wireless radios. An RJ45 port remains for an isolated LAN. No internet access needed. Ever.
Camera-free workflows
Machines ship without optical cameras. Files can be moved on hardware-encrypted USB.
Offline firmware updates
Updates arrive on a USB package you stage, validate, and approve. No forced online updates, no phone-home.
Optional LAN, never the internet
Run on a dead-end VLAN or with no network cable at all. Setup and day-to-day printing never ask for internet access.

“Siemens has selected Prusa as a trusted partner and preferred supplier of professional-grade 3D printers for manufacturing aids and prototypes production. We greatly appreciate Prusa's reliable data handling, printing performance and durability.”
Certificates and compliance
ISO 9001, 14001 and 45001, TAA/NDAA, declarations of conformity, and Letters of Volatility.
- ISO 9001, 14001 and 45001. Quality, environmental, and occupational health management, audited across EU and US production.
- TAA and NDAA. Country-of-origin transparency for U.S. federal, military, and defence procurement.
- Built in Prague and Delaware. We make our own electronics on our own PCB line.
- Letters of Volatility. Available so reviewers can document what the printer stores and what a power cycle clears.
- Open, auditable software. Firmware and PrusaSlicer are open source.
“There is a real risk that data on prints, design models, or production processes could be transmitted to servers beyond the user's control, including to the territory of the PRC.”
Prusa is the secure option
95% of desktop 3D printers sold are made by Chinese companies. Prusa is the remaining 5%. Country of origin matters.
All Chinese companies are required to cooperate with state intelligence (National Intelligence Law, 2017), hand over encryption keys (Cryptography Law, 2020), and provide data to authorities regardless of where it's stored - even on EU or US servers (Data Security Law, 2021). Product designs and 3D models a legitimate target too (2023 Counter-Espionage Law update).
There is a real risk that data on prints, design models, or production processes could be transmitted to servers beyond the user's control, including to the territory of the PRC.
Jurisdiction follows the company, not the server.
NATO armed forces trust Prusa printers
Relied upon by the majority of NATO militaries for rapid prototyping and tactical part production inside strict SCIF environments. Hardware-level air-gapping keeps operational readiness without an IT-security violation.
Data Volatility
Hardware architecture engineered for data hygiene. No mass storage, verified sanitisation, and I/O that stays under your control.
Verified volatile data sanitisation
System architecture: The product uses volatile GRAM for the xLCD unit and SRAM (260 kB on XLBuddy; 36 kB on Dwarf) for internal MCU functions and local graphical storage.
Sanitisation protocol: All volatile memory is sanitised through a standard power cycle. No operational data remains once power is removed.
For easy security audits
Open source - inspect every line
PrusaSlicer and the printer firmware are open source. Source is on our GitHub. Verify claims, run an independent audit, or compile and flash your own firmware.
The entire PrusaSlicer codebase is open, every module. There are no black boxes or DLLs downloaded at runtime.
