What is an X3G file?
3D printer file format used by desktop 3D printers with MakerBot or Sailfish firmwares such as MakerBot Replicator, FlashForge, and Wanhao; contains 3D model printing instructions.
The X3G format is designed to deliver instructions from a 3D model file, such as .STL or .OBJ, to a 3D printer in order to print the 3D object. The X3G file is primarily used by MakerBot Replicator and can be sent to the printer via an SD card or connected USB cable.
