- +Direct drive on a bed this large is unusual and useful for flexible materials

Buy these with it
A printer does nothing without these. Grab them in the same order.
- ELEGOO PLA filament, 1kgThe easy filament to start on. Prints at low temperatures and warps less.
- ELEGOO PETG filament, 1kgTougher and more heat tolerant than PLA, for parts that get handled or sit in the sun.
- SUNLU filament dryer S1 PlusWet filament causes stringing and rough surfaces. A dryer fixes that before you blame the printer.
