Some metadata may not survive

Your FBX file may contain FBX properties metadata. 3MF has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.

En el dinámico mundo de la impresión 3D y el diseño asistido por computadora, la interoperabilidad de formatos es clave. Si trabajas con modelos 3D, es probable que te hayas encontrado con el formato FBX, ampliamente utilizado en animación y desarrollo de videojuegos. Sin embargo, para la manufactura aditiva, el 3MF se ha consolidado como una opción superior, ofreciendo una representación más completa y eficiente de tu diseño. Nuestro conversor de FBX a 3MF está diseñado para facilitar esta transición, asegurando que tus modelos conserven toda su riqueza de datos —desde mallas y texturas hasta materiales y colores— al prepararlos para la impresión. Optimiza tus flujos de trabajo y da el salto a un formato que abraza las capacidades modernas de la impresión 3D, sin perder un ápice de la complejidad de tus creaciones originales.

  • Diseño de prototipos industriales
  • Modelado arquitectónico y urbano
  • Creación de material didáctico 3D

En el ámbito educativo y de pequeñas y medianas empresas en América Latina y España, la adopción de 3MF está creciendo, impulsada por iniciativas que buscan estandarizar la impresión 3D. Esto facilita la colaboración y el intercambio de archivos entre universidades y empresas locales.

Now for the details. FBX is Autodesk's 3D interchange format supporting animation, materials, and skeletal data. 3MF (3D Manufacturing Format) is an open standard designed for 3D printing workflows. Converting between these two formats lets you convert between formats quickly.

Full Name: FBX uses Autodesk FBX, while 3MF uses 3D Manufacturing Format. Compression: FBX uses Lossless, while 3MF uses Lossless. Typical File Size: FBX uses 1–500 MB, while 3MF uses 1–50 MB.

Your FBX file is decoded and re-encoded as 3MF. Converting FBX to 3MF maintains high quality with CocoConvert's optimised encoder settings.

CocoConvert runs entirely online — no software to install, no account to create. Your files are encrypted during upload (TLS), processed on isolated servers in Germany, and permanently deleted after 24 hours. It works in Chrome, Safari, Firefox, Edge, and all mobile browsers.
