Quoted from Mr_Tantrum:I'm going to disagree with you on this one (with a caveat). If you want to do multi-color by layer printing, it really couldn't be much easier now (when I first started multi-color printing it was via manual g-code injections). Simply right click the layer bar in slicer, click "insert filament change" (or whatever the setting is), generate g-code as you always do, and print away. If using a single filament printer, it will automatically pause and walk you through the filament change (I've done literally thousands of filament swaps on my old Prusa MK3S+ when printing layered multi-color prints). If you are doing something basic, design as you normally would. However, if you are designing a model that is intermediate to advanced, then you'll have to teach yourself to think in terms of printing in color layers when designing your models.
The caveat is if you want to do true multi-color prints, it takes a little more knowledge and configuration, so I would say you should be fully aware of how your slicer and printer work in general before jumping to this type of printing. While the painting tool in the slicers do okay, there are still improvements to be had. There are still models I have that I cannot color correctly using the current slicing paint tools, which leaves me figuring out a different way (e.g. printing in parts and gluing, possibly redesigning, etc.) Also, you cannot intermix using the paint tool and doing layer filament color changes.
I agree, I have been way more successful on the Bambu than with my other printers, plus with Orca slicer, I can dial settings in. I did learn alot with Cura and Prusa slicers, don't get me wrong, however I still find myself lowering my speeds with multi color prints, sometimes fast isn't best.
The learning curve is different for everyone and I appreciate that everyone comes in here and talks about how they approach aspects of modeling.
I know I struggle with pause and insert, but I will get it soon enough. My wish is that all levels of 3D hobbyists keep enjoying the experience.
