Prusa 3D printers for critical infrastructure are the secure option.




Designed and manufactured in the EU and USA. Air-gapped by hardware, not by a software switch.
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.
Americko-evropská společnost s výrobou ve Wilmingtonu a Praze. Vše, co děláme, děláme interně, a to včetně výroby vlastní elektroniky na naší SMT lince. Celý výrobní řetězec je pod naší kontrolou.

“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.”

“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.”
95% of desktop 3D printers sold are made by Chinese companies. Prusa is the remaining 5%. Country of 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.
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.
Hardware architecture engineered for data hygiene. No mass storage, verified sanitisation, and I/O that stays under your control.
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.

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.
Fast onboarding, minimal room for user error, and wide material support. Critical Infrastructure 3D printers from Prusa Research.

High-volume enclosed production. Advanced materials. Zero connectivity.

The fastest secure multimaterial platform in this class.
