Description
Fomrix STL Viewer is a free STL viewer online for opening and inspecting mesh geometry in the browser without an account. Rotate and zoom the model, inspect triangle counts and dimensions, and keep the original file unchanged. The viewer does not certify printability. This listing covers the independent STL viewer only; Fomrix AI model generation is separate and requires an account and credits.
No-Login Task
"Open an STL mesh, rotate and zoom it, and inspect triangle counts and dimensions without creating an account."
Editorial Review & Verification
Hands-on Verified3D printing hobbyists, mechanical engineers, makers, and CAD designers who need to rapidly inspect STL mesh geometry, verify triangle topology, and check dimensional bounds in a private browser viewport without installing heavyweight desktop software.
+ Key Strengths (Pros)
- ✓ Zero registration required with immediate local drag-and-drop STL loading and instant sample model inspection
- ✓ Comprehensive geometry diagnostics reporting exact triangle counts (14,564 faces), bounding box extents, and physical dimensions
- ✓ Five distinct WebGL inspection modes including surface, wireframe, vertices, surface normals, and clay rendering
- ✓ Clean export pipeline allowing instant download of original binary STL files (728,284 bytes) without modification or watermarking
− Limitations (Cons)
- − Recorded 1 first-party consent preference network beacon upon declining analytics
- − Focuses strictly on geometry inspection and does not perform automatic slicer toolpath generation or printability repair
Deep Privacy & Sandbox Audit & Product Power & Utility Review
3D mesh parsing and WebGL shader rendering execute entirely within local browser memory; custom CAD models are never uploaded to remote servers, and only 1 first-party consent endpoint was contacted when declining telemetry.
CADES 2.0 Route A dogfooding verified in ego-browser Chromium. Navigated to fomrix.com/stl-viewer and opted out of data collection via the privacy consent dialog. Loaded the 711.2 KB space-wrench STL model, confirming local WebGL initialization. Audited geometric metadata (14,564 triangles, 33.13 x 114.23 x 26.00 mm bounding box) and switched between surface and wireframe display modes. Triggered '下载原始文件' to export an authentic 728,284-byte binary STL artifact with zero watermarking. Maintained 95ms max task latency and 0.02 CLS with only 1 consent request observed.
