Arrow Exporting 3MF (3D Manufacturing Format) Files

Okino's 3MF export conversion system intelligently and robustly converts from the world’s most popular and complex 3D programs (MCAD, AEC, DCC and VR/AR) into 3D Manufacturing Format (3MF) files for subsequent 3D printing.

The 3D Manufacturing Format (3MF) is a 3D printing file format spearheaded by Microsoft that allows design applications to send full-fidelity 3D models to other 3D applications, platforms, services and 3D printers. As explained by Microsoft, "3MF files describe the appearance and structure of 3D models for the purpose of manufacturing (3D printing)." It was primarily designed to replace the simplistic and aging 1987-era STL file format for 3D printing (as well as OBJ and VRML2).

Arrow Features of the 3MF Exporter

  • Accurate conversion from all sources of primary 3D data files, including MCAD, AEC, DCC and VR/AR software applications and file formats.

  • Full geometry instancing support throughout the conversion pipeline from 3D file import to 3MF file export.

  • Layered texture map support with automatic embedding and resizing of JPEG and PNG bitmap images. This exporter has a unique and intelligent method to determine how to deal with 3MF’s oddities relating to layered texture images (see examples further below in this help).

  • Conversion from all supported source 2D bitmap image file formats to embedded JPEG or PNG images within the 3MF file, of variable width/size and bit depth.

  • Support for multiple layers of uv texture coordinates for each exported geometry object.

  • Export of vertex colors and/or mixing of vertex colors with an object’s surface (diffuse) color.

  • Support for the 3MF Core Specification and the 3MF Materials Extension.

  • Mesh processing options such as automatic polygon reduction, explode-by-material assignment, sort polygons by material and coordinate list optimizations.

  • Multiple methods to embed pivot points in the geometry data.

  • CAD-like units matching.
