This coaster uses 5 different filaments in one print using Prusa Slicer's colour change feature. Each filament should extrude for a few layers to allow the colour to be strong and vibrant. The difference in height is minuscule and is not noticeable when complete.

We used PLA filament from our own shop for this. Check out our range here: https://www.3djake.com/3d-printer-filaments/pla-filament-product-range
