A great place to buy

You can buy your printer anywhere, but mine was opened up when I got it. Why did they do it? To check out the printer and give me a caramel apple lollipop to eat while I assemble it and a note of encouragement. This the the company your ordering from, one that cares. Definitely get your printer and supplies from here, its one of the last few that understand what customer service is.

Great machine

Great price. Even deal. Great service. Prompt shipping


We've spent a long time deciding which printer we'd bring bring in next. At West3D we don't want to be the store that carries everything but knows nothing (ehem...), so when we set out to bring in another 3D printer it has to fit the following criteria:

  1. Be a printer we want to print with so we can learn and be a valued resource.
  2. Run Klipper, the same firmware we use on our printers so that we can support customers who need help, and also so that customers can move to other West3D supported printers easily.
  3. Easy to set-up and get printing with quality results. Let's face it, not everyone is ready or ever wants to be ready to build a Voron. We wanted a printer that could appeal to both entry-level customers as well as experienced makers. 
  4. Priced competitively. We are makers ourselves, and understand the hobby isn't an easy one to come into, nor maintain if you're buying a $1,000 machine. This printer has all the quality of life features everyone will enjoy.

In our words here are some of the main features of the Neptune 4 Pro:

  • This printer comes pre-installed with Klipper firmware, and runs Fluidd Web UI out of the box, so you can control, monitor, and print over your network safely and reliably.
  • 2 part cooling fans on the toolhead and 4 (yes 4) auxiliary part cooling fans offer one of the best cooling solutions we've ever seen on a 3D printer. This allows you to print PLA and other filaments that like cooling very quickly.
  • 225x225x265 mm build surface, with auto bed leveling and filament runout sensor 
  • Upgraded motion components, including metal wheels, make this a more reliably, and speedy option.
  • Direct drive extruder allows for printing of flexible filaments more easily.
  • Flexible PEI sheet allows you to easily remove prints, no tape, glue or other tricks others need to use.
  • Touch Screen display lets you adjust print settings without being near your computer. 
  • LEDs in two places give you visibility in all conditions.

This printer comes mostly pre-assembled, and can be setup following the instructions in less than an hour.

Don't just listen to us about how cool this is - look at this lady, she spilled her Coffee and this printer came to her rescue!

Now some information on the printer from Elegoo's words:

Main Features: 

  • 【Pre-installed Klipper Firmware】The Neptune 4 Pro 3D printer is designed to be fast and efficient. It features a quiet Klipper motherboard and ARM 64-bit 1.5G main frequency quad-core processor for sufficient processing power, allowing it to print at a amazing speed of up to 500mm/s  (recommended 250mm/s), and supports advanced functions like input shaping and pressure advance to achieve accurate and smooth models.
  • 【Dual-Gear Direct Drive Extruder】The dual-gear direct drive extruder with a 5.2:1 reduction ratio for smooth and consistent extrusion, combined with the copper-titanium bi-metal throat pipe and unique air duct design, improve heat dissipation and reduce nozzle clogging.
  • 【300°C High-temp Nozzle】With a high-temperature nozzle reaching 300°C, the printer can handle a wide range of filaments, including PLA, PETG, ABS, TPU, and high-temperature filaments like nylon. The extended hot end design ensures consistent heating and faster melting and extrusion, resulting in faster printing speed.
  • 【Intelligent Segmented Heatbed】With 100W+150W power output, the slicing software automatically recognizes the size of the model during slicing and activates the peripheral heating zone if the model size exceeds the center heating zone (120mmx120mm). The two partitions can also be turned on and off manually for more precise temperature control. Additionally, the surface of the PEI magnetic platform is marked for guidance.
  • 【Auto Bed Leveling + Auxiliary Leveling】With 121 (11x11) points auto bed leveling, you can achieve consistent and reliable prints every time without the need for manual bed leveling. Additionally, the auxiliary leveling by hand-twist knobs allows for further fine-tuning of the print bed's level for improved print quality.
  • 【Efficient Heat Dissipation】ELEGOO Neptune 4 Pro also features 2 thickened double-sided 4015 ball bearing cooling fans and 4x4020 ball bearing blower fans behind the print head for omnidirectional rapid cooling the newly printed layers to prevent warping and improve overall print quality even at a fast printing speed.
  • Powerful Extrusion Mechanism

    The printer's dual-gear direct drive extruder is another key feature that ensures smooth and consistent extrusion, weighing only 75% of the weight of the Neptune 3 Pro. The 5.2:1 reduction ratio and dual-gear design ensure a firm grip on the filament and prevent the flexible filament from slipping and grinding. The copper-titanium bi-metal throat pipe has a unique air duct design for faster heat dissipation of the throat pipe and less nozzle clogging.

    The 300°C high-temp nozzle with an extended hotend design to fully melt the filament, and you can explore a wider range of materials, such as PLA, PETG, ABS, TPU, and high-temp filaments like nylon.

    Separate Segmented Heatbed

    ELEGOO Neptune 4 Pro features an intelligent segmented heatbed for added efficiency and energy-saving, and a hot bed overheat protection switch to prevent thermal runaway causing hot bed damage or fire. The heatbed can be set to 100W to heat only the center area (120mmx120mm), making it ideal for smaller models. For larger models, the heatbed can be set to 250W, heating the entire surface area. The two partitions can also be manually controlled for flexible temperature adjustments.

    PEI magnetic platform with a special coating and spring steel sheet for good adhesion and anti-warping, just gently bend the print steel plate to release or pop off the prints.

    Efficient Cooling System

    To ensure rapid and omnidirectional cooling of newly deposited models, the Neptune 4 Pro has two thickened 4015 ball bearing cooling fans on each side of the print head and four 4020 ball bearing blower fans behind it. This cooling system allows the hot filament to bond quickly for better overhang and bridge results even at a fast printing speed, preventing issues like warping or deformation.

    More Practical Features

    The printer can resume printing after an unexpected power failure, thanks to its power loss recovery function. With a filament detection sensor, when the filament runs out or breaks, the printer will pause and alarm.

    Support LAN networking printing, once connected, you can use the WEB terminal to remote control and monitor your printer on the same network.

    The XY-axis belt tensioner is easy to adjust with a hand-twist knob, and the widened Y-axis profile ensures a stable printing platform.

    The 4.3-inch removable capacitive screen supports 8 languages and can be used handheld or fixed on the machine base. It features a printed model preview and a pause printing function to monitor printing progress and make adjustments as needed.

    The gantry's LED light bar and nozzle LED light can be operated via the screen's button for conveniently observing model printing in a dark environment.
