Extprint3r — ((top))
In the rapidly evolving landscape of additive manufacturing, a new name has been surfacing among engineers and industrial designers: . As industries pivot from rapid prototyping to high-volume end-use production, the demand for machines that combine speed, material versatility, and industrial-grade reliability has never been higher.
The use of exploitation tools such as Extprint3r raises significant ethical questions. While some may view it as "white-hat" testing or simply "finding workarounds," these activities often cause disruption to legitimate services and may infringe on the privacy and security of other users.
: By freezing administrative extension pages (like Securly or GoGuardian ), users can effectively "neutralize" the software that tracks their web activity or blocks certain websites. Usage Recommendations
Connecting an unmanaged personal device to the school's public Wi-Fi tier. Accessing personal email or chat applications safely. Minimal Risk
An attacker (or a student trying to bypass school monitoring) activates the ExtPrint3r script. This is often done by clicking a specially crafted bookmarklet saved in their browser's bookmarks bar. extprint3r
When the user attempts to print the page while these iframes are flooded, the embedded extension page "hangs" or freezes, effectively disabling its filtering or monitoring capabilities. Consistency:
Because the Extprint3r prints large objects (often 1m³ or larger), warping is a serious risk. Premium units feature actively heated chambers that maintain ambient temperatures of 60°C to 90°C, ensuring that massive ABS or Polycarbonate prints do not peel off the bed.
If you are convinced that Extprint3r is the right path, here is a buying checklist:
Google and filter developers (like Securly or Hapara) frequently release updates to block these exploits, meaning older versions of the tool often stop working on newer ChromeOS versions. In the rapidly evolving landscape of additive manufacturing,
Before committing to expensive molds, startups use Extprint3r for "bridge production"—manufacturing the first few hundred units of a product to test the market. This lowers the barrier to entry for new hardware companies. The Software Integration
Understanding ExtPrint3r: The Technical Mechanics, Impacts, and Mitigation of the ChromeOS Extension Bypass
t1-n on Oct 8, 2025. Original comment in English - Translate to English. can somebody help me disable securly, chrome version 140. CVE-2025-6179 Detail - NVD
According to the advisory, the vulnerability allows a local attacker to bypass extension management controls on managed Chrome devices, disable existing extensions, access Developer Mode, and potentially load additional unauthorized or malicious extensions. The fact that this CVE includes a reference to ExtPrint3r elevates the tool from a simple user-level exploit to a documented security risk recognized by Google and the broader cybersecurity community. While some may view it as "white-hat" testing
School IT departments monitor device statuses using centralized dashboards. If a mandatory extension stops reporting data while a student is actively logged into the network, flags are automatically raised, resulting in disciplinary action or the loss of laptop privileges.

ExtPrint3r exploits specific resource and print rendering behaviors to break this isolation:
extprint3r is a lightweight, real-time extrusion monitoring and visualization tool for 3D printers (Klipper/Marlin + OctoPrint compatible). It tracks your extruder’s behavior down to the mm/s and mm³/s, then gives you clean graphs and alerts.
: Chrome extensions often register specific assets (like HTML configuration pages or images) as web_accessible_resources . This allows standard web pages to interact with or embed elements of the extension. ExtPrint3r maps these accessible endpoints for target administrative extensions.
