Multi-Material Printing on a Single Extrusion 3D Printer

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!

That is great!!! Do you have a tutorial on how you design something like that?

I think my biggest hang up(noob) is figuring out how to separate the colors in the design by layer. Alot of multicolor files have all colors mixed throughout design

Greetings, Great Instruction I'm new to the 3D Printing scene, and have ideas to create some prints that serve a Utility function, and would like your advice on how to go about printing out something that is mostly hard, though has three sides that will clip onto a rail, so those edges would maybe be TPU, a filament that gives or clicks into place when pushed together.... Gluing would not be an option, as I would not trust it in the long Any information in printer models and Ext heads would help....

Hey! I used a flexible filament in my Dremel 3D45 and then paused the print and changed the filament to a PLA and manually edited the settings on the printer and now my printer is mad and no filament is coming out even when I’m hitting purge.. any idea on how to fix? Also, if I do the settings correctly next time, have you done a print where you toggle between flex and PLA In one print successfully? Thx!

why would you use pause at to change filament over the change filament script?
