Convert S3G to another file type
To convert S3G toolpaths to another format, you need ReplicatorG or other 3D software.
Convert a file to S3G
To convert other file formats to the "3D Printer Toolpath File" file type, you need software like ReplicatorG or a similar tool.
About S3G files
The .S3G file is a Sanguino3G toolpath file used by legacy 3D printers to execute print jobs. It stores compiled machine instructions that dictate exactly how the 3D printer's stepper motors and extruders must move to build an object layer by layer. Historically, these files were generated and managed using ReplicatorG and older software from MakerBot Industries. The major disadvantage of the .S3G format is its highly specific, proprietary nature. It is a compiled, packetized version of G-code, meaning it is not human-readable. It cannot be opened in a standard text editor, and modern 3D printing slicers outright reject it. Users typically need to convert .S3G to standard .GCODE to read the instructions, or to the newer .X3G format to run the print on newer MakerBot hardware. Reversing an .S3G file back into a standard 3D mesh like .STL or .OBJ is virtually impossible, as the file contains only toolpath coordinates, not structural 3D geometry. This file format is difficult to open or convert because standard online converters fail to process machine-level binary code. Often only the original software can properly read or export the data.
Convert.Guru analyzes your S3G file, detects the exact format, and lets you read the text inside.
If you want to convert S3G file to OBJ, FBX, DAE, 3DS, MAX, BLEND, MA, MB, C4D, STL, PLY or WRL, you can use ReplicatorG or similar software from the "3D Printer Toolpath Storage" 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 S3G, try ReplicatorG or another comparable tool in the "3D Printer Toolpath Storage" category.
The S3G 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 S3G converter.
