3d printing. I need advice, which printer? Child friendly? Easy for non Computer guy to use?

To speed printing up you can change the quality of the print, the fill level, and a few other tweaks within the slicer type program.

has a grab bag of filaments that you can use to help dial in the printer with a specific type of filament. Only used this material on a few items that seemed to work ok.
Freq sales, and I think free shipping. The grab bag you request the size of the filament and the style (PLA, etc), and they pick an over stocked color.
