What is an L3B file?

An L3B file is a 3D LEGO file created by SR 3D Builder, a program used to build digital 3D LEGO models. It contains the dimensions of a 3D LEGO model which include their placements within a 3D coordinate system. L3B files can be used to store a variety of LEGO models such as dune buggies, trucks, and front end loaders.

More Information

While the L3B file is used to store LEGO models, you cannot print the model using the L3B file. However, you can open the L3B file with the LDview program and export it to the .STL format, which can be used for printing.
