Convert X3G to another file type
To convert your X3G file to another format, you need ReplicatorG or other 3D software.
Convert a file to X3G
To convert other file formats to the "Printer Toolpath" file type, you need software like ReplicatorG or a similar tool.
About X3G files
A .x3g file is a binary instruction file used primarily by MakerBot Replicator and FlashForge 3D printers running Sailfish firmware. Unlike standard gcode files, which contain human-readable text instructions, .x3g is compiled machine code based on the S3G protocol. This format presents a challenge: because it is binary, you cannot open it in a text editor to modify temperatures, speeds, or retraction settings. Additionally, .x3g files are hardware-specific; they contain hard-coded steps-per-millimeter values tailored to a specific printer's mechanics, meaning a file sliced for a Replicator 2 may fail catastrophically on a FlashForge Creator Pro. To audit the file's contents, verify print paths, or migrate the instructions to a different machine, users need to convert .x3g back to standard gcode or readable text formats. While ReplicatorG was the historical standard for this, modern workflows often require conversion tools to visualize the output.
Convert.Guru analyzes your X3G file, detects the exact format, and lets you read the text inside.
If you want to convert X3G file to STL, GCODE, OBJ, FBX, DAE, 3DS, MAX, BLEND, MA, MB, C4D or PLY, you can use ReplicatorG or similar software from the "3D Printer Binary Instructions" category. In the File menu, look for Save As… or Export….
To convert DWG, DAE, X3D, IGES, WRL, JT, SKP, 3DS, 3DM, OBJ, STEP or FBX files to X3G, try ReplicatorG or another comparable tool in the "3D Printer Binary Instructions" category.
The X3G Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our X3G converter.
