In this 3D printing how-to, Mr.E shares tips and methods for 3D printing with multiple filament types and colors on a standard 3D print with a single extruder head. There isn't one single right way to do this, but through this tutorial Mr.E shares his personal favorites, as well as methods for how to automatically pause at a certain layer height using his LulzBot Mini 2 and the Cura LulzBot edition slicer by automatically modifying the GCode.

While Mr.E demonstrates these tips using his LulzBot, similar methods are doable on other types of FFF or FDM 3D printers including Prusa, Creality, Ultimaker, Makerbot, and more!
