Compress STL format using C#

STL Compression Overview

Aspose.ZIP for .NET offers a high-performance C# API for compressing STL 3D assets in .NET projects. You can process individual files or collections, use streams for I/O, and tune compression levels to match storage and transfer needs. This is useful for packaging models and related assets for delivery or backup. Archive STL data into ZIP, 7Zip, TAR, GZIP, and more with no third-party tools; encryption and password protection are available for sensitive content. This makes automation straightforward for build pipelines, backups, or content distribution workflows.

C# Example: Compress STL Files Programmatically

The snippet below illustrates the basic API workflow for compressing a STL file, including archive creation, entry addition, and saving the final ZIP output.

Compress STL file via .NET:

    var dir = "full directory path";
    using (var arch = new Archive())
    {
    arch.CreateEntry("filename.stl", dir+"file.stl");
    arch.Save(dir+"archived_result.zip");
    }

FAQ

Can I compress multiple STL files into a single ZIP archive using C#

1. Yes. Aspose.ZIP for .NET allows you to load and compress multiple STL files by adding each file as an entry to the Archive object. You can combine individual files, folders, or streams into a single ZIP archive through a straightforward C# workflow.

Does Aspose.ZIP for .NET reduce the original quality of STL files?

2. No. Aspose.ZIP performs lossless compression, meaning that the content and quality of your STL files remain unchanged. The library only reduces file size by applying efficient archive compression algorithms without altering the actual data inside the file.

Can I password-protect ZIP archives that contain STL files?

3. Yes. The library supports password protection and AES encryption, allowing you to securely package sensitive STL files. You can specify encryption settings when creating entries or during the archive-generation process.
