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.
3D打印与建模日益普及，许多设计师和工程师在工作中会接触到不同格式的文件。AMF（Additive Manufacturing File Format）作为一种先进的3D制造文件格式，能更好地描述复杂的几何形状和材料信息。然而，在实际应用，尤其是在需要更广泛兼容性或优化文件大小的场景中，将AMF转换为3MF（3D Manufacturing Format）变得尤为重要。3MF格式以其开放性、高效性和对现代3D打印功能（如多材料、颜色、纹理）的良好支持，正逐渐成为行业新标准。本工具旨在帮助您顺畅地完成AMF到3MF的转换，确保您的3D模型在不同平台和设备间无缝流转，提升工作效率，让您的创意不受格式限制。

- 文创产品快速打样
在大中华区，特别是在制造业和教育领域，3MF格式因其对多色彩和多材料打印的良好支持，以及在主流切片软件中的广泛兼容性，正受到越来越多的关注。相比AMF，3MF在文件大小和解析效率上往往更具优势，便于通过微信等平台进行分享和协作。
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.
