Proprietary format tied to 3D Systems ecosystem.

Best For

Users within the 3D Systems software ecosystem.
Sending models to 3D Systems printers.
Maintaining specific material or surface finish data.
Creating models intended for direct 3D printing.

Less Ideal For

General 3D asset exchange between different software packages.
Web-based 3D rendering or interactive applications.
Formats requiring broad compatibility and open standards.
Archiving for long-term preservation without specific software.

Common Use Cases

Preparing 3D models for additive manufacturing.
Transferring designs between 3D Systems software.
Storing intermediate or final 3D project data.
Archiving 3D print ready files.

How to Open It

Open the .3dk file using 3D Systems' proprietary software like Cubify Design or other compatible applications from their suite.
If the file is part of a 3D printing workflow, it may be directly importable into slicer software bundled with 3D Systems printers.
Look for specific import options within the software that originally created or was intended to use the .3dk file.

What is a .3dk file?

The .3dk file extension is primarily associated with 3D modeling and printing software, specifically from 3D Systems. It is a proprietary format designed to store 3D model data, including geometry, material properties, and potentially assembly information. This format is often used as an intermediate step in the 3D printing workflow, allowing users to prepare and transfer complex models between different software applications or to the printer itself. Because it's a proprietary format, compatibility and editing capabilities can be limited to specific software suites developed by 3D Systems.

Common Problems with .3dk Files

⚠️ Cannot open .3dk file with non-3D Systems software.

Use proprietary 3D Systems software or convert the file to a more compatible format like STL or OBJ within that software.

⚠️ Limited editing capabilities outside of native software.

Perform complex edits in native software, then export to a standard format if further modifications are needed elsewhere.

Frequently Asked Questions

Is .3dk a standard 3D file format?▼

No, .3dk is a proprietary format developed and used by 3D Systems, not an industry-wide standard.

Can I open .3dk files on any computer?▼

You can generally only open .3dk files using specific software from 3D Systems, typically on Windows or macOS.

Why would I use a .3dk file?▼

.3dk files are primarily used for preparing 3D models for printing with 3D Systems hardware and software, preserving specific print-related data.

Technical Details

A .3dk file is a binary format that encapsulates 3D model data. It stores geometric information such as vertices, faces, and normals, along with associated data like color, texture coordinates, and material definitions. The specific internal structure and compression methods are proprietary to 3D Systems and are not publicly documented, making it challenging to parse or manipulate with third-party tools.

Did You Know?

The .3dk format is designed to integrate closely with 3D Systems' entire additive manufacturing ecosystem.

It often contains data crucial for specific 3D printing processes that more general formats might omit.

Security Information

As a proprietary binary format from a known manufacturer, .3dk files are generally considered safe. However, always download files from trusted sources to avoid potential corruption or manipulation.
