Convert Your 3D Mesh/Model PTX Files to STL

to

Our free and fast tool will convert most 3D mesh or PTX (Point Cloud) 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.

To convert your PTX 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 PTX to STL conversion process see the conversion information section below for more information.

FAQ

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.

How can I convert my PTX file to STL?

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

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

We aim to process all PTX 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 PTX to STL conversion?

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

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

Yes, of course! We do not store the PTX file you submit to us. The resulting STL file, once created is deleted 1 hour after upload and the download link will expire after this time.

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

Yes! Our PTX 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.

File format information for PTX to STL

Extension: PTX

Full Name: Point Cloud

Type: 3D Model

Mime Type: text/plain

Format: Text

Description

The PTX is a 3D file format used for representing 3D Point Clouds. The format contains only positional information (X, Y, Z coordinates) for the individual points. The format is often used for digital elevation modelling of terrain for later processing in 3D modelling applications.

As the format only contains positional information a common task is to convert this into a fully surfaced 3D model using methods such as Alpha Shapes or Delaunay Triangulation. The format can also be viewed without further processing in its raw format.

PTX Notes

The PTX file format was designed to store vertex information only to allow the construction of simple Point Cloud models.

Supported Features

  • Mesh vertex data

Extension: STL

Full Name: Standard Triangle Language

Type: 3D Model

Mime Type: application/vnd.ms-pki.stl

Format: Text & Binary

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
