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 ABC file, once uploaded to our server, will be deleted 15 minutes after upload, so please download your converted ABC file before this time.

Our 3D model ABC to STL tool will load your ABC 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 ABC file to STL?

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

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

We aim to process all ABC 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 ABC 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 ABC to STL work?

In order to successfully convert an ABC formatted file to the STL format, our converter tools will perform several initial checks to ensure the file provided is indeed an ABC 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 ABC files to the exact specification.

Take your ABC file

An ABC 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 ABC 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 ABC to STL

Now that the data from the ABC 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 ABC 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 ABC to STL converter will always save the STL file in a binary format.

File format information for ABC and STL

Extension	ABC
Full Name	Alembic
Type	3D Model
Mime Type	application/octet-stream
Format	Binary
Opens With	Blender

The ABC file format is a 3D format created by Sony Pictures and Industrial Light & Magic. It has been designed to store 3D model information, including animations and other useful data that can be harnessed in the television and movie industries.

The format can store all the information required to represent a digital 3D world, including camera settings, 3D models, and all their associated geometry, such as vertices, normals, faces, textures, and other specialist materials that govern the rendered look of the model, along with all animation sequences.

Support for the ABC format can be found in all modern 3D modeling and rendering applications, including the ever-popular Blender which offers both an import and export option for ABC files.

ABC Converter Capabilities

When converting 3D model or mesh files using our ABC converter, we will attempt to convert color materials into a suitable format for use in the converted file.

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 modeling 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 flavors: 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.

When converting your ABC to STL, our tool will attempt to accurately convert any color or material information.

Information for converting from ABC to STL

Your ABC file will be converted to a STL file using our unified 3D model and mesh conversion tool. Our ABC 3D tool performs accurate conversions of 3D elements such as vertices, faces, normals, and relevant material information. As both ABC and STL support color material information, our tool will also attempt to convert the color information.
