Free Online STEP to 3MF Converter

The STEP file format, also known as ISO 10303-21, is a 3D file format used within the area of computer-aided design (CAD) as a way to exchange data between different applications. The STEP format is essentially a plain text file containing commands used to describe the 3D object.

Due to the standardized nature of the format, there is support for importing STEP files into many CAD applications. STEP files can, however, become quite large, and some complex files can take a long time to import into a 3D project.

Mesh Geometry

The STEP format is not a mesh-based format; converting a STEP file to a mesh format is possible via most CAD applications via a tessellate function.

As materials containing color information is supported by the STEP format, our tool will do its best to include this in the converted file.

The primary purpose of the 3MF format is to store and transmit 3D models for 3D printing. The format is ideally suited to this due to its ability to store not only the 3D model but also additional metadata required for 3D printing an object, such as units of measurement, surface material characteristics, and more.

Mesh Geometry

The 3MF file format is a mesh-based format; more specifically, the mesh is stored as a series of triangles that, when combined, can represent any 3D object. The format can contain many 3D mesh objects in a single file.
