Frequently Asked Questions

What does this tool do?

Our tool converts image (bitmap) data into 3D Geometry which is then saved out to the common .STL file format.

Is it free to use?

Yes. Our conversion tool is 100% free to use.

What files does it support?

The tool can convert the most common image file formats such as .PNG and .JPG. The output is provided in .STL format which can be used in most 3D graphics applications.

What is an .STL file?

The STL file format describes an unstructured triangulated surface of the triangles using a 3D Cartesian coordinate system. STL files do not contain any scale information, and the units are arbitrary.

How does the tool interpret the image pixel data?

3D Geometry is created based on the luminosity of each pixel in the source image. For example using the default tool settings, a black pixel represents a 3D pixel height of 0mm and a white pixel represents a 3D pixel height of 10mm. Colors inbetween these will be converted to a 3D pixel between this range.

What does the "Invert Output" do?

This option reverses the black-to-white range conversion, so with this option set a black pixel will be rendered as a 3D pixel of 10mm in height and a white pixel will be rendered as 0mm.

How do I control the Model detail?

The "Detail" option allows you to control the resolution of the created STL file. Low detail will generate the model quickly and will result in a smaller file. The High option will take longer to generate and can result in very large download files.

What does the "Enable Smoothing" do?

With this option the converter will attempt to remove or smooth out any spikes in the resulting 3D model. Spikes are usually caused by highly contrasting adjacent pixels in the source image.
