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

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

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

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

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

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

Take your VTP file

The VTP file format is a text-based format, meaning its contents are human-readable, making VTP files easy to edit in simple text editors. Within this text-based format are the core elements that make up the 3D model, including vertices, faces, and more. To ensure efficient conversions, our tool will check all data that is contained within the VTP 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 VTP to STL

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

File format information for VTP and STL

Extension	VTP
Full Name	Visualization Toolkit
Type	3D Model
Mime Type	application/octet-stream
Format	Text

The VTP file format is the successor to the older VTK format. Updated to store data in a structured XML format rather than the bespoke plain text structure of the VTK format. The same 3D elements that could be stored within a VTK file can be transferred to the VTP format.

As VTP files are based on plain text XML, binary 3D model data can be encoded using the Base64 encoding method, which allows binary data to exist within plain text structures such as XML. This binary model data consists of common 3D geometric elements such as vertices, faces, and surface material information.

The VTP format also allows 3D model data to be stored in a compressed format prior to the Base64 encoding process to help reduce the overall file size. VTP files can be imported into several 3D editing applications, and we have a set of VTP conversion tools to convert these files to other popular 3D formats, such as STL.

VTP Converter Capabilities

Our VTP 3D Model/Mesh tool does not support any color material data contained within VTP files, so the converted file will not contain any color 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 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

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

Information for converting from VTP to STL

Your VTP file will be converted to a STL file using our unified 3D model and mesh conversion tool. Our VTP 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 color information if it is present in your VTP file; your final 3D model will contain only geometry data.
