Free Online MAX to STL Converter

You can use our MAX to STL conversion tool to quickly and easily convert your 3D model files for free. You may upload up to 20 files at one time, and our batch MAX to STL converter will process each 3D model and present you with a download link for each file once completed.

Select File(s)

Or drag and drop your files here to upload.
A maximum of 20 files can be uploaded at once.

Please note: Your MAX file, once uploaded to our server, will be deleted 15 minutes after upload, so please download your converted MAX file before this time.

Our 3D model MAX to STL tool will load your MAX file and, where supported, attempt to extract all the relevant 3D features, such as geometry, textures, and animations. To access the 3D conversion configuration options, click the button when you have selected your files. The current options support the ability to voxelize your 3D model and more.

Frequently Asked Questions

How can I convert my MAX file to STL?

First, click the "Upload..." button and select your MAX file to upload. Your MAX file will be uploaded to our servers. When the MAX to STL conversion has completed, you can download your STL file right away.

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

We aim to process all MAX to STL conversions as quickly as possible; this usually takes around 5 seconds; however, this can be longer for certain files, so please be patient.

How accurate is the MAX to STL conversion?

We aim to provide the best conversion experience. Our tools are under constant review and development, with new features being added every week.

How does converting MAX to STL work?

In order to successfully convert an MAX formatted file to the STL format, our converter tools will perform several initial checks to ensure the file provided is indeed an MAX file. There are many files out there where the file type extension does not match the data contained within the file. Along with these file type checks, our tools will do additional checks to ensure the file is correctly formatted to match the provided file type. There are many tools out there that do not always create MAX files to the exact specification.

Take your MAX file

An MAX file is a binary data file containing 3D data that makes up the 3D model, including vertices, faces, texture coordinates, and more. To guarantee efficient conversions, our tool will check all data that is contained within the MAX file and remove any information that is duplicated. This not only ensures the conversion completes more quickly, but also the generated STL file size is smaller.

Convert the data from MAX to STL

Now that the data from the MAX file has been processed, our tool can apply any conversion specified options, such as enabling Voxel mode, and with these applied, prepare the data to be converted to the final STL file format. Part of this process ensures checking the capabilities of the STL format and removing any data that cannot be represented.

Save to the STL format

At this point, the MAX to STL conversion tool will have the 3D model in a state that is ready to be transferred to the STL format. Our tool creates the STL file, ensuring all the model data is present and is formatted to match the STL file specification to ensure the file opens in compatible STL file editors. To ensure a compact file size, our MAX to STL converter will always save the STL file in a binary format.

File format information for MAX and STL

Extension	MAX
Full Name	Autodesk 3ds Max
Type	3D Model
Mime Type	application/octet-stream
Format	Binary

A MAX file is the native (and proprietary) format of the 3D model editing software 3ds Max by Autodesk. 3ds Max is popular in a wide range of sectors, including video games, movies, professional animation, and amongst other 3D modelling enthusiasts.

The MAX file is the successor to the older 3DS format and was created to address the limitations of that format. A MAX file can contain 3D modelling data along with textures, animations, and scene lighting information, all within a single compact file format.

As already mentioned, the format is proprietary, and MAX files are designed to be opened and edited within the 3ds Max software only; however, it does provide options to export to formats such as FBX, which can then be converted to other formats using our FBX conversion tools.

MAX Converter Capabilities

Our MAX 3D Model/Mesh tool does not support any colour material data contained within MAX files, so the converted file will not contain any colour information.

Extension	STL
Full Name	Standard Triangle Language
Type	3D Model
Mime Type	application/vnd.ms-pki.stl
Format	Text
Opens With	Blender, MeshLab, CAD Assistant, DAZ Studio

The STL, or Standard Triangle Language, file format has been around since the '80s and is supported by most modern 3D modelling applications. In particular, the STL format has become something of a standard format within the area of 3D printing, despite the rise of more modern formats such as 3MF.

STL files come in two flavours: binary or text format. The text format is human-readable, making it easy to perform manual edits, but can lead to very large file sizes. As you can imagine, the binary format is much more compact and represents the majority of the STL files you are likely to encounter.

The format itself is very simple; the 3D model is represented by a sequential list of triangles, with each triangle defined with 3 points consisting of their X, Y, and Z positions, along with an additional vector that contains the face normal (the direction the face is pointing). There is an additional attribute block for each triangle; however, this is largely unused and thus unsupported.

STL Converter Capabilities

Our 3D conversion tool does not support colour or material information in STL files, so your file will not contain any colour information.

Information for converting from MAX to STL

Your MAX file will be converted to a STL file using our unified 3D model and mesh conversion tool. Our MAX 3D tool performs accurate conversions of 3D elements such as vertices, faces, normals, and relevant material information. Our tool will not attempt to transfer any colour information if it is present in your MAX file; your final 3D model will contain only geometry data.
