STL Slicer

Effortless 3D Model Slicing

The STL Slicer tool simplifies the preparation of large 3D models for printing by automatically dividing objects into manageable segments. By uploading your STL file, the system can identify the longest axis and split the model based on your specified maximum part size. You can choose between various connector types, such as pin and hole or snap fit, to ensure that pieces align perfectly during reassembly. Manual cuts are also available for precise control over where the model is divided.

Secure Browser-Based Processing

Your privacy is a priority when using our online tools. The STL Slicer processes your files directly in your web browser, meaning your data never leaves your device or reaches our servers. This ensures that your proprietary designs and intellectual property remain secure while you prepare them for 3D printing. By utilizing local processing, we provide a fast and private way to manage complex geometries without the need for cloud uploads.

How do I split a large STL file?

Simply upload your STL file to the tool and set the maximum part size in millimeters. The system can automatically detect the longest axis to suggest optimal cut lines, or you can manually add cuts at specific positions to divide the model into segments that fit on your 3D printer's build plate.

What are pin and hole connectors?

These are mechanical joints used to join printed parts together. A pin and hole connector creates a male and female connection point, while a snap fit provides an interlocking mechanism. Both options ensure that your sliced components align accurately when you reassemble the final 3D object after printing.

Can I manually choose where to cut the model?

Yes, the tool offers both automatic and manual cutting modes. While auto-cut uses the longest axis for convenience, the manual cut feature allows you to specify exact coordinates or positions. This gives you full control over how segments are divided based on specific structural requirements or your printer's limitations.

Is my data safe when using this online tool?

Yes, your data is secure because the processing happens entirely within your web browser. Your STL files are not uploaded to a server; instead, the calculations and slicing operations occur locally on your machine. This ensures that your designs remain private and protected during the preparation process.
