The MPD file extension, which is also known as an LDRAW file, is a 3D graphics file format whose specialty is providing a format to store and display 3D Lego models.
With LDRAW-formatted files, complex Lego constructions can be defined using individual bricks. It is an open format with a large library of existing files that are freely available to download.
MPD files can be opened with the LDraw software, or you can use our range of MPD file converters to process MPD files into other formats.

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

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