Well, we’ll both find out how they are, I ordered one from 3dprintersonlinestore on 4-20-18.

On filament, PLA is good for most of what you’re going to print.

I’d skip ABS due the toxic smell/difficulty to use.

You might want to get some type of flexible filament like a TPE/TPU, but I don’t know if the extruder is setup for it.

Here is my first experience with a TPU that I got on sale from HobbyKing I had to modify my extruder to feed it properly without problems.
