Convert Your 3D Mesh/Model AMF Files to STL

Our free and fast tool will convert most 3D mesh or AMF (Additive Manufacturing File) model files to a standard STL (Standard Triangle Language) file that can then be edited further in most popular 3D editing packages such as Blender or 3D printed without any further processing. Our conversion tool can also batch convert multiple AMF files, up to 25 files at a time can be converted.

To convert your AMF file click the Upload button above and select the file to convert. Once selected, the file will be converted to a STL file and will ready for download shortly afterwards. For more information about the AMF to STL conversion process see the conversion information section below for more information.

How to Convert your AMF to STL Online?

Here are 2 simple steps to convert your AMF to STL.

Upload a AMF

Click the "Upload a AMF File" button and select a AMF to upload. The maximum file size is 100MB.

Download your STL

Click the download link once completed to receive your STL file.

Frequently Asked Questions

How can I convert my AMF file to STL?

First click the "Upload..." button, select your AMF file to upload. Select any configuration options. When the AMF to STL conversion has completed, you can download your STL file straight away.

How long does it take to convert my AMF to STL?

We aim to process all AMF to STL conversions as quickly as possible, this usually takes around 5 seconds but can be more for larger more complex files so please be patient.

How accurate is the AMF to STL conversion?

We aim to create the most accurate conversions with our tools. Our tools are under constant development with new features and improvements being added every week.

Is it safe to convert my AMF to STL on ImageToStl.com?

Yes, of course! We do not store the AMF file you submit to us. The resulting STL file, once created is deleted 15 minutes after upload and the download link will expire after this time.

Can I convert AMF to STL on Windows, Linux, Android, iOS or Mac OS?

Yes! Our AMF to STL tool will run on any system with a modern web browser. No specialist software is needed to run any of our conversion tools.

What if I am using an Ad Blocker, will that affect things?

Yes. Although you can use an Ad Blocker, if you like our AMF conversion tool please consider white-listing our site. When an Ad Blocker is enabled there are some conversion limits on some of our tools and processing/conversion times will be longer.

What STL formats can I convert to?

Our tool will save all STL files in binary format. Optionally, our tool will allow you to save to the non-standard color STL format.

I have several AMF files, can I batch convert my AMF to STL?

Yes! Our AMF tool supports full batch conversions. You can upload up to 25 AMF files at a time. Our tool will convert them all as quickly as possible. Once completed, you can either download the STL files individually or download them all in a single ZIP file.

How does it work?

Converting from the AMF file format to STL can be a complex process and any tool used for this conversion process needs to be able to handle a variety of data conversion tasks as well as identify any defects within the 3D model and fix them. Here we will explain the conversion process used by our tool to accurately convert your AMF file to a valid STL 3D model. Lets start with the conversion process, which involves the following steps:

Step 1: Read the Source AMF File

In its simplest form, an AMF file is a plain text file containing human readable 3D data such as vertices, faces, normals and more. When combined, these make up the 3D model you see on your screen.

Step 2: Process File Data

With the AMF file data read, our tool generates an internal representation of the full 3D model and will attempt to fix any geometry issues encountered. Along with repairing any issues with the 3D model, the tool will remove any duplicated vertices and prepare the model ready for exporting to the STL format.

Step 3: Saving to the STL Format

The STL format has been around for many years and has become a standard format for 3D printing. Most 3D printing software can open STL files which means our tool now needs to take the in-memory 3D model we have created in step 2 and convert this to the STL format.

Description

The AMF or Additive Manufacturing File format is an open standard 3D file format primarily used within additive manufacturing processes such as 3D printing. The initial release version of the file was in 2011 and the format continues to be developed today.

As this is a 3D file format the contents which are XML based describe one or many 3D objects broken down into solid volumes defined with vertices and triangles. The format has support for color and texture materials.

AMF Notes

When converting from AMF files our tool will try to convert any geometric and color data found in the model file.

  • Mesh colors

Description

The STL file format has its roots in the 1980's and is the native file format for 3D Systems stereolithography CAD software. The format defines a triangulated mesh with vertices and faces and is a popular format for sharing 3D printable model files.

There were several formats that attempted to extend the STL format namely SolidView and VisCAM whose formats included limited 15-bit color information for each mesh face which is often ignored by most modern 3D software. The STL format can be either Text or Binary, our tools will support both formats.

STL Notes

The standard STL file format does not support colored faces or vertices or texture information. The STL file generated by the tool will contain only raw mesh/triangle data by default which is perfect for 3D printing.

The tool also has an option to save the file to one of the non-standard formats that support colored faces such as VisCAM and SolidView which is perfect if you want to further process the STL in software which supports these formats.

Supported Features

  • Mesh geometry
  • Face colors via the VisCAM and SolidView formats
  • Binary and Text versions supported
