PrusaSlicer automatically detects if you insert an SD card, USB flash drive, or other removable media.
When detected, a new Export to SD/USB drive button will appear next to the Export G-code button (bottom right corner). Clicking it will open the file save dialog with the path initialized to the SD card or USB flash drive.
<div class="note-callout">If multiple SD cards or USB flash drives are detected, the file dialog is opened at the last visited removable media.</div>
Once a G-code is exported to a removable media, an Eject button is shown next to the Export G-code&nbsp;button, which will safely disconnect your device.

Binary G-code is a new standard for encoding and compressing ASCII G-code files. G-code files are easy to read and interpret, but their downside is that the data is not saved efficiently, and the file size is often very large. Compression of the file is problematic because the printers usually run on limited hardware and they may not have enough memory and/or CPU power to decompress it.
<h3>Binary G-code</h3>
The binary G-code format is flexible and the encoding and compression of individual blocks is variable. We also provide <a href="https://github.com/prusa3d/libbgcode">libbgcode</a> library which contains the routines to convert ASCII G-codes to binary and vice versa. The library is written in C++ and the repository includes bindings for Python.
Our testing shows that using binary G-code reduces the average size by about 70%.
<img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/2023/12/1051e8b3c87b66248093cae5dbfbd916.jpg" sizes="(min-width: 1024px) 820px, 100vw" srcset="Binary G-code" alt="" width="700" height="387" loading="lazy" />
<h3>Slicer requirements</h3>
The support for the .bgcode file format is implemented in PrusaSlicer, including its export, loading configs, and previewing G-code or file associations. Exporting binary G-code can be enabled in Printer Settings-&gt;General-&gt;Support binary G-code. This option is enabled by default starting from PrusaSlicer version <a href="https://www.prusa3d.com/drivers/">2.7.0</a>. An option to convert ASCII G-code to binary (or the opposite) has been added to the File menu.
<img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/2024/01/bd82f4018b4d5fa8cdcc6f325b43deb8_painted.png" sizes="(min-width: 1024px) 820px, 100vw" srcset="Binary G-code" alt="" width="1600" height="1176" loading="lazy" />
<h3>Disabling binary G-code export for all profiles</h3>
You can disable the use of binary G-code even globally for all profiles in the Preferences - Other - Use binary G-code when the printer supports it.
<img decoding="async" loading="lazy" src="https://cdn.help.prusa3d.com/wp-content/uploads/2024/01/1d12f4145b574b865e1c83b8b66cc85f.png" sizes="(min-width: 1024px) 820px, 100vw" srcset="Binary G-code" alt="" width="1422" height="1319" />
<h3>Firmware requirements</h3>
To print a binary G-code, it has to be supported by the firmware of the printer. For Original Prusa MINI, MK4, and XL printers, it is supported starting from firmware <a href="https://www.prusa3d.com/drivers/">5.1.0</a>. It is necessary to update the <a href="https://help.prusa3d.com/downloads">printer firmware</a> before using the binary G-code format.
<h3>Compatibility issues</h3>
Some external printer control programs like Octoprint might have an issue with the binary G-code. In this case, disable the binary G-code feature in PrusaSlicer.

All models on the print bed and all of PrusaSlicer settings can be saved as a single <a href="http://help.prusa3d.com/article/saving-projects-as-3mf_1773">3MF Project file</a> via the File - Save menu.
<div class="tip-callout">Uploading a 3MF file is a great way to share your model online. Compared to STL, 3MF includes additional information such as thumbnail, custom supports, variable layer height, and more!</div>
Alternatively, all models on the print bed can be exported as a single STL via File - Export - Export plate as STL.
You can also export individual models as STL. Right-click on any of the models in the 3D view and select Export as STL...&nbsp;This can be useful if you created changes to the model inside PrusaSlicer, such as cutting the model.

In the SLA mode, it’s possible to also include tree supports (as non-editable STL) via the File - Export plate as STL including the supports menu.
Deprecated
Lastly, the entire platter can be exported as AMF via the File - Export - Export plate as AMF menu.
