Can the CI Edition run offline without mandatory cloud connectivity?

Yes. The CI positioning is built around offline-first operation so slicing, print execution, and day-to-day workflows stay inside your controlled environment.

Is air-gap alone enough for secure deployment?

Not by itself. Review firmware-update procedure, removable-media policy, document handling, network segmentation, and who can access print files during operation.

How should procurement teams treat NDAA and country-of-origin review?

Use origin transparency and procurement documentation as part of internal review. Final compliance determination follows your organisation's own legal and contracting rules.

Does the CI Edition require proprietary cloud software or locked materials?

No. Positioning is based on open workflow control, auditability, and avoiding mandatory cloud lock-in or forced proprietary material dependency.

What does the Letters of Volatility package help answer?

It helps security reviewers understand what data the device may store and what should be considered in cyber and records-handling review.

Does the CI Edition support WPA2-Enterprise Wi-Fi deployments?

No, motherboards for our Critical Infrastructure printers do not include a wireless radio.

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.

PrusaSlicer running locally without a network connection

Open, auditable software

PrusaSlicer is open-source and runs on your own workstation. No cloud account, no subscription, no telemetry calling home.

Prusa printer with no persistent mass storage

Zero residual data

No internal mass storage. Volatile memory, including SRAM used for print buffering, is wiped by a power cycle.

Hardware-encrypted USB transfer on a Prusa CI printer

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.

Prusa printer in a defence manufacturing environment

Camera-free workflows

Machines ship without optical cameras. Files can be moved on hardware-encrypted USB.

Open-source firmware that can be inspected and flashed offline

Offline firmware updates

Updates arrive on a USB package you stage, validate, and approve. No forced online updates, no phone-home.

Prusa CORE One L CI Edition operating offline

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.

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.
