Why Do I Recommend The Neptune 4 Pro? 

  • The Neptune 4 Pro has a 500mm/s high-speed printing capability powered by Klipper Firmware for faster print times and smoother motion control compared to the Neptune 3 Pro’s 80mm/s speed with standard Firmware.
  • Neptune 4 Pro features industrial-grade metal rails and double-row ball U-shaped bearings on the X and Y axes for improving stability, precision, and reducing wear compared to the Neptune 3 Pro’s standard frame construction.
  • It features a 121-point auto bed leveling system for ensuring higher precision and better first-layer adhesion, whereas the Neptune 3 Pro features basic automatic leveling.
  • The Neptune 4 Pro’s high-flow hotend and 300°C maximum nozzle temperature enable compatibility with high-temperature filaments like Nylon and Carbon Fiber, whereas the Neptune 3 Pro’s 260°C limit.
  • Neptune 4 Pro has multi-fan cooling system for enhancing overhangs, bridging, and overall print quality, while the Neptune 3 Pro has a single cooling fan.
  • It uses a flexible PEI-coated bed with segmented heating for better adhesion, faster heating, and easy print removal, while the Neptune 3 Pro has a standard PEI-coated build plate without zoned heating.
  • The Neptune 4 Pro features Ethernet connectivity to control and monitor prints remotely, whereas the Neptune 3 Pro relies on USB and microSD only.
  • Neptune 4 Pro’s 310W power output delivers faster heat-up times, improved stability, and consistent performance, outperforming the Neptune 3 Pro’s 250W power supply.

Maybe the Neptune 3 Pro price can make you comfortable because it’s a little bit cheaper than the Neptune 4 Pro. But you have to compromise all the above-mentioned features. Now the Decision is Yours. I hope it was helpful to choose the right one.
