Trusted Supply Chain. TAA Compliant
DEVELOPED AND MANUFACTURED IN THE EU & USA
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.
NATO Armed Forces Trust Prusa Printers
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.
Integrated Security Architecture: Protecting the Entire Path from CAD to Print
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.
USB‑Only Transfers
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.
PrucaSlicer: Local, Open, Offline
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.
Zero Residual Data
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.
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.
Offline Updates
You can update the firmware offline, using a USB drive. No forced firmware updates.
No internet access needed. Ever.
You can run CI machines on a dead‑end VLAN or with no network cable at all.
No Telemetry Transfer
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.
No Relying on Software Switches
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.

Letter of Volatility
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.
Verified Volatile Data Sanitization
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.
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).

Why "Software Security" is a Dangerous Illusion
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.

Critical Infrastructure Workflow in Four Steps
1
Design and preparation on approved workstations
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.
2
Controlled Transfer
Print files are transferred using an encrypted USB workflow by default, allowing customers to preserve air-gapped or high-side operating conditions.
3
Local 3D Printing
The printer executes jobs locally, without requiring a cloud or remote authorization step to perform manufacturing.
4
Controlled maintenance
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.
Your Data Never Leaves the Room
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.
Hardware‑Level Air‑Gap
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.
No‑Cloud‑By‑Design
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.
Camera‑Free & Secure Workflows
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.
Zero Vendor Lock‑in
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.
Open, Auditable Software Supply Chain
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.
