Some metadata may not survive
Your AMF file may contain AMF metadata metadata. 3MF has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
AMF（Additive Manufacturing File Format）から3MF（3D Manufacturing Format）への変換は、3Dプリントやデジタル製造の現場で、データの互換性と効率を高めるために不可欠なプロセスです。AMFは、色や素材情報を細かく保持できる一方で、ファイルサイズが大きくなりがちという特性があります。対する3MFは、よりモダンな形式として、これらの情報を効率的に扱いながら、ファイルサイズを最適化し、さらに複数のモデルやスライスデータも統合できる利点を持っています。この変換ツールは、お客様の貴重なデータが持つポテンシャルを最大限に引き出し、次世代の製造ワークフローへとスムーズに移行するためのお手伝いをいたします。複雑な設定は不要で、直感的な操作で高品質な変換を実現します。

日本のアニメや漫画関連の3Dモデル制作において、AMFで保持された豊かな色彩やテクスチャ情報を3MFへ正確に移行することは、最終製品の品質を左右するため特に重要視されています。
About AMF to 3MF Conversion
AMF (introduced 2013) and 3MF (introduced 2015) are both 3d model formats, but they differ in important ways. AMF (Additive Manufacturing Format) is an XML-based 3D printing format supporting materials and colour. 3MF (3D Manufacturing Format) is an open standard designed for 3D printing workflows.
Full Name: AMF uses Additive Manufacturing Format, while 3MF uses 3D Manufacturing Format. Compression: AMF uses None (uncompressed), while 3MF uses Lossless. Typical File Size: AMF uses 1–50 MB, while 3MF uses 1–50 MB.
When you convert AMF to 3MF, the goal is to convert between formats quickly. Converting AMF to 3MF maintains high quality with CocoConvert's optimised encoder settings. Understanding these technical differences helps you choose the right format for your workflow.
Your AMF file is decoded and re-encoded as 3MF. The conversion involves 4 steps: (1) your amf file is uploaded and the format is validated, (2) the file content is decoded into its raw representation, (3) the data is re-encoded in 3mf format with optimal settings, (4) the converted file is ready for download.
CocoConvert's converter handles the entire pipeline server-side using FFmpeg, Sharp, and qpdf — battle-tested libraries used by streaming platforms and enterprise tools. Files are encrypted in transit and deleted within 24 hours.
This conversion is ideal when you When you specifically need a 3MF file for your workflow. For the opposite direction, CocoConvert also supports 3MF to AMF conversion.
How to Convert AMF to 3MF
- 1
Upload .amf file
Select your AMF file by dragging it to the upload zone or using the file picker. Batch upload is available for multiple files.
- 2
Choose .3mf
Set 3MF as the output format. The converter uses optimal settings based on the AMF→3MF conversion profile.
- 3
Convert
The server-side engine decodes your AMF file and re-encodes it as 3MF. Processing time depends on file size and complexity.
- 4
Download result
Grab your converted .3mf file. Multiple output files can be downloaded together.
