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

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

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

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

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

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

Take your STL file

The STL file format can be either a text-based or binary format, meaning if its content is plain text, it is human-readable; otherwise, if it is binary, then it can only be edited with specialist STL editing software. The data within the file, regardless of whether it is text or binary, is structured in a very simple manner. A 3D model is composed of many triangles, with each triangle comprising 3 vertices. The STL format is simply a sequential list of triangle vertices, which can lead to duplicated data. To guarantee efficient conversions, our tool will check all data that is contained within the STL file and remove any information that is duplicated. This not only ensures the conversion completes more quickly but also that the generated BLEND is smaller.

Convert the data from STL to BLEND

Now that the data from the STL 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 BLEND file format. Part of this process ensures checking the capabilities of the BLEND format and removing any data that cannot be represented.

Save to the BLEND format

At this point, the STL to Blender conversion tool will have the 3D model in a state that is ready to be transferred to the Blender BLEND format. Our tool creates the BLEND file, ensuring all the model data is present and is formatted to match the BLEND file specification to ensure the file can be opened in Blender and other editors that are capable of editing BLEND files.

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.

STL Converter Capabilities

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

The BLEND file extension is the native 3D modeling file format of the ever-popular Blender 3D modeling software. The Blender format originally came into existence in late 1994 and has since evolved into the advanced 3D format we have today.

The format stores complex 3D mesh data along with textures, animations, lighting, and other information related to 3D scene rendering. The format is popular among those creating 3D videogame graphics and animation sequences due to its advanced features and ease of use.

Along with Blender, BLEND files can also be imported into other popular 3D editing software. The open-source nature of the format allows third-party plugins and scripts to be created to run within the Blender editing environment and extend the format's capabilities.

BLEND Converter Capabilities

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

Information for converting from STL to BLEND

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