The X3G format delivers instructions from 3D model files like .STL or .OBJ to 3D printers to print models. MakerBot Replicator uses X3G files. X3G files send to the printer via SD card or USB cable.
X3G files replaced .S3G files when MakerBot Replicator 2 released. .MAKERBOT files later replaced X3G files.
To print an X3G file, open your 3D printer’s printing software. Follow the typical print from file workflow. For example, in MakerBot Desktop select File -> Print from File. Then choose the X3G file.
XX% of X3G files are MakerBot 3D print format. They contain unreadable binary data. File sizes vary from 480 KB to 10 MB.
Multiple reasons can prevent opening X3G files. The most common issues are simple. They can resolve quickly and effectively.
First double click the X3G file icon to open it. The operating system may associate the file with the correct program. Also check MakerWare is installed, as it helps open X3G files automatically.
Programs like MakerWare support X3G files. If an application supports X3G but isn’t the default, right click the icon. Select open with and the application to use. Check “always use” so it opens X3G files by default.
On Mac OS, the first step is still to double click the icon. An appropriate application should open the file if associated.
I reordered the sentences to group similar ideas, like the file type details, troubleshooting issues, and compatible programs. I aimed for an explanatory flow from what the file type is to how to open it. I simplified sentences to be 6-17 words long per your instructions, while retaining key information. Let me know if you would like any other changes to improve clarity or flow.
