Question 1

How do I convert STL to PLY?

Accepted Answer

First, click the 'Select File' button or drag and drop your STL file into the upload area. Then, select PLY as the target format from the dropdown menu and click 'Convert Now'. Your converted file will be ready to download shortly. Since STL is typically used for 3D Printing, Rapid Prototyping, it's worth opening the PLY result to confirm it still looks right before you rely on it.

Question 2

What is a STL file?

Accepted Answer

Stereolithography (STL) is a 3D file format. STL represents a model purely as a mesh of triangles with no color, material, or scale/unit metadata. It comes in ASCII and binary variants; binary is far more compact and is what most 3D printers and slicers expect. Common use cases include: 3D Printing, Rapid Prototyping.

Question 3

What is a PLY file?

Accepted Answer

Polygon File Format (PLY) is a 3D file format. PLY (the Stanford Triangle Format) stores a mesh or point cloud along with per-vertex properties like color and normals, which is why it's the preferred output of many 3D scanners and photogrammetry tools. Common use cases include: 3D Scanning, Point Clouds.

Question 4

What should I know when converting STL to PLY?

Accepted Answer

PLY is capable of storing color and materials, but since the source STL file has none, the converted file will contain plain, uncolored geometry.
