What format should my SD card be for Ultimaker 2 3D printing?

Ultimaker is a leading 3D printer brand from the Netherlands, popular in schools, factories, and design studios. Their printers build objects layer by layer using melted plastic (FDM technology). When using models like the Ultimaker 2, you'll often load your 3D print files from an SD card.

What format should my SD card be for Ultimaker 2 3D printing? For the Ultimaker 2 to recognize the card and read your files properly, the SD card must be formatted using the FAT32 file system. This specific format is essential for the printer's older controller to work correctly. While FAT32 can technically handle very large cards, it's best to use a smaller, standard SD card between 8GB and 32GB in size (an SDHC type) for reliable performance.

SD Cards larger than 32GB, even if formatted to FAT32, can sometimes cause problems like SD card not showing full capacity. So, for smooth printing on your Ultimaker 2, stick with a smaller SDHC card and ensure it's formatted as FAT32 using your computer's tools before loading your print files.
