Prusa Research is a Czech 3D printer manufacturer with new production facilities located in the USA. Our machines are completely designed and manufactured in-house. We control every part of the supply chain and even produce PCBs in our facility in Prague.
Fully TAA and NDAA compliant, the Prusa CI Edition adheres to rigorous country-of-origin standards to streamline acquisition for U.S. federal, military, and defense agencies. Our hardware, manufactured by Prusa Research a.s. in the European Union, contains no restricted components, facilitating a transparent approval process for mission-critical procurement programs.
Internationally recognized certifications guarantee that your hardware is built in secure, heavily regulated, and strictly monitored environments.
Relied upon by the majority of NATO militaries, Prusa's Critical Infrastructure printers empower rapid prototyping and tactical part production directly within strict SCIF (Sensitive Compartmented Information Facility) environments. Featuring verifiable, hardware-level air-gapping and completely offline workflows, these systems guarantee continuous operational readiness without ever risking an IT security violation.


True security demands a governed workflow, not just an offline printer. Our architecture minimizes your attack surface across the entire data lifecycle. From air-gapped production to secured Hybrid Enterprise (LAN-only) deployments.

Eliminate wireless risks with hardware-encrypted USB transfer. Electronics for the CI editions are custom-made and do not feature any wireless radios. The printer still features an RJ45 ethernet port so it can be connected to the local area network. No internet access needed. Ever.

Prepare your mission-critical prints without an internet connection. The industry-leading slicing software runs entirely locally on your secure network. It requires no cloud account, demands no subscription, and sends zero telemetry back to the manufacturer.

The system architecture contains no internal mass storage like hard drive or persistent memory. All volatile memory, including SRAM used for print buffering, is completely wiped by a simple power cycle, ensuring no print files remain on the printer after a USB drive is disconnected.
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.

Wireless radios are completely removed from the custom-made mainboards.
Printers are not equipped with built-in cameras. They are an optional upgrade.
You can update the firmware offline, using a USB drive. No forced firmware updates.
You can run CI machines on a dead‑end VLAN or with no network cable at all.
Without access to Prusa Connect (a fully optional remote print management system), these 3D printers do not send telemetry, usage statistics, print data, or any other information to Prusa Research or third parties.
Many brands claim that disabling wireless radios via a software switch in the menu is enough. We know it's not. Our platform does not contain a wireless radio and doesn't allow connection of Wi-Fi USB modules.

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.
Our hardware architecture is engineered for complete data hygiene and transparent memory management. By eliminating mass storage and implementing verified sanitization protocols, we ensure that sensitive operational data is never persistent and remains fully under your control.
System Architecture: The product utilizes volatile GRAM for the xLCD unit and SRAM (260 kB on XLBuddy; 36 kB on Dwarf) for internal MCU functions and local graphical storage.
Sanitization Protocol: All volatile memory is 100% sanitized through a standard power cycle, ensuring no operational data remains once power is removed.
95% of desktop 3D printers sold are made by Chinese companies. Prusa is the remaining 5%. And the origin matters.
“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.”

“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.”
When a 3D printer is connected to an external network or runs on closed-source software, you expose your enterprise to critical threats.
Instead of asking operators to trust configuration menus, cloud policies, or marketing claims, our systems remove attack vectors at the hardware level and support workflows that remain entirely within the customer’s own security boundary.
| RISK | The Threat | The Prusa Solution |
|---|---|---|
| Intellectual Property Theft (Espionage) | Storing your proprietary CAD files and G-codes on cloud-connected printers means handing your trade secrets to third-party servers. A single breach can cost you your competitive advantage. | We don’t just disable wireless features; we physically remove the Wi-Fi and Bluetooth chips from our custom mainboards. With zero outbound telemetry and no cloud connectivity, your data physically cannot leave the room. |
| Part Sabotage (Undetectable Modification) | Cyber attackers can secretly modify your G-code (e.g., reducing internal infill density or changing extrusion temperatures). The printed part looks perfect on the outside but catastrophic fails under stress. A critical danger for aerospace and defense. | Our ecosystem, including PrusaSlicer, runs 100% offline. Files are transferred exclusively via certified encrypted USB drives (included) or an isolated, highly secure LAN. What you slice is exactly what you print. |
| Firmware Trojans (The Black Box Problem) | Relying on proprietary printers from unverified overseas manufacturers means trusting a "black box." Hidden malware within closed-source firmware can act as a backdoor into your facility's wider network. | Our firmware is open-source and fully auditable line by line. Designed and manufactured in-house in the EU and the US, the Prusa CI Edition guarantees a transparent supply chain and is fully TAA Compliant for federal procurement. |
CAD and slicing happen on your approved workstation using your existing internal workflow. PrusaSlicer is part of an open and inspectable software ecosystem, which gives security teams visibility unavailable in closed, black-box toolchains.
Print files are transferred using an encrypted USB workflow by default, allowing customers to preserve air-gapped or high-side operating conditions.
The printer executes jobs locally, without requiring a cloud or remote authorization step to perform manufacturing.
Firmware updates can be delivered offline through USB packages, enabling organizations to stage, validate, and approve changes within their own maintenance process. Firmware source code is available on Github.
The Prusa CI Edition is designed from the ground up for high-stakes environments where compromise is not an option. We deliver absolute physical and digital isolation, ensuring your intellectual property remains strictly in your hands.
Wi-Fi and Bluetooth modules are physically omitted from our custom-built mainboards. There is zero risk of wireless intrusion because the hardware for it simply does not exist. Without RF or RFID components, there is no signal to track and no wireless backdoor to exploit. Every volatile memory bank, from the display unit to the MCU, clears instantly with a simple power cycle.
Your designs stay on your terms, not ours. The entire Prusa ecosystem, including PrusaSlicer, operates strictly offline, requiring no cloud accounts, mandatory telemetry, or internet access to function. Your G-codes and CAD models remain internal, kept within your secure facility where they belong. We don’t harvest data; we provide the architecture to protect it.
Visual security is non-negotiable in sensitive environments, which is why these machines ship without optical cameras. Data transfer moves through physical, hardware-encrypted USB drives rather than vulnerable network protocols. No proprietary geometric data persists on the machine once the drive is pulled.
By designing and manufacturing our electronics in-house across the EU and US, we offer a transparent, TAA-compliant supply chain that is fully auditable. Our open-source firmware allows your security teams to inspect every line of code, ensuring your production remains independent of geopolitical shifts or arbitrary vendor decisions.
All core components of the Prusa ecosystem – from firmware on the xBuddy mainboard to the PrusaSlicer toolchain – are open‑source and fully auditable. There are no opaque proprietary binaries running on unknown SoCs; you can inspect, build, and verify exactly what runs in your environment.
We maintain a public security policy and vulnerability disclosure program, including a security.txt file on our domains and a documented process for intake, triage, and remediation of reports. We reward meaningful security findings based on impact and treat external security researchers as partners, not adversaries.
