Air-Gapped 3D Printers for Critical Infrastructure
Your 3D printer might be the weakest link in your cyber security.
Prusa printers are built for organizations that need the performance of modern additive manufacturing without inheriting the hidden risks of cloud-dependent hardware and software

NATO Armed Forces Trust Prusa Printers
Relied upon by the majority of NATO militaries, Prusa Critical Infrastructure printers are used for prototypes and parts in controlled rooms, including SCIFs. The motherboards have no Wi-Fi or Bluetooth radios, the printers ship without a camera, and the print can move via USB or Ethernet.
Key Security Features
You can run our machines completely offline. They will not ask you for internet connection - not even once. The entire initial setup and firmware updates can be performed without an active internet connection.
No Wi-Fi Module
Wireless radios are completely removed from the custom-made mainboards.
No Camera
Printers are not equipped with built-in cameras. They are an optional upgrade.
No internet access needed. Ever.
You can run CI machines on a dead-end VLAN or with no network cable at all. Even firmware updates can be done completely offline.
No Telemetry Transfer
We do not send telemetry, usage statistics, print data, or any other information to Prusa Research or any third parties.
Open Source - For Easy Security Audits
PrusaSlicer and the printer firmware are open-source and you can find all source codes on our Github. You can easily verify all our claims, run a thorough independent audit, or even compile your own firmware and flash it into your 3D printer.
The entire PrusaSlicer code is open-source - all components, every module. There are no black boxes or DLL libraries downloaded on runtime. Everything is available for a thorough inspection. No fine print, no asterisks.
Certificates and compliance
ISO certificates, declarations of conformity, warranty terms, and a few items we issue on request.
ISO 9001, 14001 and 45001
Quality, environmental and occupational health management - all audited.
CE and UKCA
Designed and manufactured in the EU and USA, including our own PCB production in Prague, TAA and NDAA compliant for government and defense procurement.
Built in Prague and in Delaware
The entire production chain is under our control. We even make our own electronics on our own PCB line.
Letters of volatility
Available on request if you need to document what the printer stores and what a power cycle clears.
One‑year warranty for businesses
60-day refund policy, 2-year warranty in EU, 1 year in the USA. 24/7 tech support in seven languages with real experienced operators in EU & USA - no AI bots.
Five years of spare parts
Guaranteed from the date of release. Every mechanical part is sold separately and nothing is glued shut.
Prusa is the Secure Option
95% of desktop 3D printers sold are made by Chinese companies. Prusa is the remaining 5%. And the 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 are a legitimate target too (2023 Counter-Espionage Law update).
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 are 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.”
Modern, Secure and Reliable
Fast onboarding, minimal room for user error, rapid speed and wide material support.

Even small details can reveal sensitive information
You don't need to share an entire 3D model to reveal what you're working on. A file name can identify a confidential project. A thumbnail can show the shape of an unreleased product. And a camera can reveal exactly what's being printed.
Prusa CI printers are designed to keep this information under your control. They ship without cameras or wireless hardware, and neither the printer nor PrusaSlicer requires a cloud connection. You can prepare your files locally, transfer them by USB, and complete the entire printing process offline.
Where data leaks are not an option, Prusa is the secure option
Forensics
Compelson
Compelson, in Prague, builds the readers investigators use to pull data off smartwatches with no data port. When the Czech Military Police needed a connector for a specific watch, it was printed in under 20 minutes and in use the next day.
Aerospace
Shark.Aero
More than 100 printed parts fly on every Shark. The molds for the plane's 200 carbon parts are proved in PLA in the hangar before any composite is laid.
Research
CERN
At the home of the Large Hadron Collider, CERN engineers utilize Prusa 3D printers to support the world's largest scientific experiments.
“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.”
Trusted by 110,000+ businesses worldwide
