Description
The Elegoo Neptune 4 Pro is engineered to deliver both speed and precision, making it one of the most exciting consumer FDM printers available today. Thanks to its pre-installed Klipper firmware and a powerful ARM 64-bit, quad-core 1.5 GHz processor, the Neptune 4 Pro can achieve a top speed of 500 mm/s, while also supporting advanced motion features like input shaping and pressure advance for smooth, accurate prints.
To ensure consistent first layers, the printer uses a 121-point (11 × 11) auto bed leveling system, providing a dense mesh to correct any surface imperfection. The build surface is a PEI-coated magnetic spring steel sheet, which offers excellent adhesion for a broad range of filaments, and makes part removal much easier.
The extrusion system is robust and precise: a dual-gear direct-drive extruder with a 5.2:1 reduction ratio ensures strong filament grip and reliable feeding, even at high speeds or with flexible materials. The hotend supports up to 300 °C, opening up printing possibilities for materials like PLA, PETG, ABS, TPU and even Nylon.
Cooling is highly optimized: the Neptune 4 Pro has two 4015 fans on the sides and four 4020 blower-style fans at the back, delivering omnidirectional cooling to maintain layer integrity at high print speeds. To maximize thermal efficiency and minimize energy use, the printer features an intelligent segmented heatbed that recognizes the model size and heats only the necessary zones.
Stability and precision are boosted by a dual Z-axis motor setup with synchronized lead screws, ensuring better motion control and layer alignment. The printer also includes silent stepper drivers, reducing operational noise to below 50 dB, making it suitable for shared workspaces or quiet environments.
User interaction is simple yet powerful: a 4.3-inch capacitive touchscreen provides intuitive control and can be removed from its base. Connectivity includes USB and LAN, so you can control the printer from a computer or network. The Neptune 4 Pro also supports filament run-out detection and power-loss resume, reducing the risk of failed prints.
With its blend of performance, precision, and modern control, the Neptune 4 Pro is ideal for users in Bangladesh who want a high-throughput, flexible 3D printer for prototyping, small-scale production, or creative projects.
Who Should Buy
- Makers & Tinkerers: Who want very fast print speeds without sacrificing quality.
- Engineers & Designers: For rapid prototyping and faster iteration.
- Startups / Small Production: High throughput for small-volume or custom parts.

FAQs
Q: Is the Elegoo Neptune 4 Pro available in Bangladesh?
A: Though not always locally stocked, it can be imported via trusted international resellers or local 3D printer importers. Always check import duties and warranty coverage.
Q: What is the realistic print speed I can achieve?
A: While the maximum is 500 mm/s, typical reliable speeds are around 250 mm/s for quality prints with Klipper.
Q: Which filaments can it handle?
A: It supports PLA, PETG, ABS, TPU, and even Nylon thanks to its 300 °C hotend.
Q: How accurate is the auto-leveling?
A: Using a 121-point (11×11) mesh, it can correct for bed irregularities precisely and consistently.
Q: Does it continue after a power cut?
A: Yes — the printer supports power-loss resume.
Q: Can I pause prints if filaments run out?
A: Yes — it has a filament run-out sensor to prevent failed prints.
Q: What kind of maintenance does it need?
A: Regularly check belt tension (it has a knob), clean the PEI bed, and ensure Z coupling is tight.
Q: Is it noisy during printing?
A: No, thanks to silent drivers and efficient cooling, it’s rated at around ≤ 50 dB.
Q: What software should I use?
A: You can use Elegoo Cura, OrcaSlicer, or other slicers compatible with Klipper.
Q: Are spare parts like nozzles standard?
A: Not entirely—the Neptune 4 Pro uses a custom bi-metal nozzle, so replacing it may require specific parts.
