Why Use a Browser-Based STL Viewer
- ✓No slicer or CAD software, View STL geometry without Cura, PrusaSlicer, Meshmixer, or any 3D application
- ✓Works on any device, Review and approve 3D models from desktop or mobile
- ✓Secure sharing, Send STL files via expiring links instead of large email attachments
- ✓Instant viewing, Mesh geometry loads directly in the browser viewer
- ✓No account for recipients, Anyone with a link can open and rotate the model

What Is an STL File?
STL (Stereolithography) is the most widely used format in 3D printing. It represents 3D geometry as a mesh of triangles and is supported by virtually every slicer, 3D printer, and CAD application. STL files are used to send models to 3D printing services, share designs for review, and distribute prototypes for feedback before manufacturing.
Viewing an STL file typically requires a slicer application (Cura, PrusaSlicer) or a 3D viewer (Meshmixer, Blender). An STL viewer online eliminates that dependency, the mesh renders directly in the browser, readable by anyone without software.
With ShareCAD you can view STL files in a browser and share them with clients, manufacturing partners, or reviewers via a link. They inspect the geometry on any device, rotating, zooming, and examining the mesh without installing anything.
STL Viewer Use Cases
Prototype review before printing
Share an STL model with the team for approval before sending to a 3D printing service. Recipients inspect the geometry in their browser without opening a slicer.
Client approval of product designs
Product designers sharing 3D-printable models with clients can send a ShareCAD link. The client views the model in the browser without needing any 3D software.
Sending to print services
Rather than emailing large STL files, upload to ShareCAD and share a link with the printing service. They open the model and confirm geometry before printing.
Open-source hardware projects
Share 3D-printable parts with collaborators or end users via a link. They view the model before downloading and printing themselves.
