Elegoo Neptune 4 Plus vs Elegoo Neptune 4 Pro

Both are Elegoo Neptune 4 machines with the same Klipper firmware, 500 mm/s top speed, 300 °C nozzle and 121-point bed leveling, so print quality and speed are close. The Plus is the one to buy if you need to print large parts or batches: its 320 × 320 × 385 mm volume is roughly three times the Pro's. The Pro is smaller, cheaper to own in space and materials, and has the stronger owner record, 4.8 from 589 ratings against 4.7 from 205. Reviewers call the Plus nearly problem-free with good to very good print quality; Pro owners praise accuracy and build but report a steeper learning curve, unclear manuals and some failed prints.

• Choose the Neptune 4 Plus if you print helmets, cosplay armor, prototypes or multi-part plates that will not fit a 225 mm bed.
• Choose the Neptune 4 Pro if your models fit 225 × 225 × 265 mm and you want the smaller footprint, the larger owner base and the same hot end and speed.
