1. Consumable Parts 
Consumable parts are either excluded from warranty coverage or covered under a limited warranty period. For the purpose of this policy, "consumables" are defined as disposable items, components, or parts of the Product that are inherently designed to deteriorate or wear out during normal use of the Product.

While these items may not be covered by the standard warranty or may have a limited warranty period as specified in the table above, we will gladly replace any consumable that fails due to a manufacturing defect, provided the printer itself is still under warranty. ELEGOO reserves the exclusive right to determine eligibility for replacement, and such decisions shall be final.

2. Accessories or Parts Purchased Separately
Accessories or parts purchased separately enjoy the same quality assurance policy as the complete machine.

3. Warranty Periods
All periods stated on this page are calculated from the date the original order was received. 

4. Warranty Forfeiture
This warranty does not cover the following cases:
A. Products not purchased from ELEGOO or authorized ELEGOO distributors with a valid receipt or invoice.
B. Products that are lost or stolen.
C. Products whose warranty period has expired.
D. Free products or products that have been refunded.
E. Products repaired by a third party or modified by an individual.
F. Damage caused by external factors or misuse of products (including but not limited to resin leakage, falls, improper operation), normal discoloration, wear and tear, or other non-quality-related issues.
G. LCD screens that can not provide an identifiable SN code.
 
5. Warranty in Other Regions
For consumers protected by local consumer laws in their country of purchase, ELEGOO's Limited Warranty benefits are provided in addition to all rights and remedies under such laws, including but not limited to those described above. If local regulations specify a warranty period longer than our stated policy, the longer period will apply, and we will fully comply with local requirements to support our customers.

Pre-installed Klipper Firmware

The Neptune 4 Plus comes with the powerful Klipper firmware, enabling impressive printing speeds of up to 500 mm/s (default 250 mm/s) and up to 12000 mm/s² accelerations, supporting advanced features such as input shaping and pressure advance calibration.

It is also equipped with acceleration sensors on the X and Y axes, ensuring automatic calibration and improved print quality.

Klipper High-speed Motherboard

Neptune 4 Plus adopts a Klipper motherboard and an ARM 64-bit 1.5G main frequency quad-core processor.

With pre-installed Klipper firmware, the printing speed can reach 500 mm/s (default 250mm/s) with up to 12000 mm/s² acceleration. The 8G ROM gives you ample storage capacity for various print files.

In addition, the printer supports input shaping and pressure advance to improve print quality and reduce issues like artifacts, filament ooze, and blobbing. With acceleration sensors on the X-axis and Y-axis to automatically calibrate resonance compensation parameters for less vibrations and precise prints.

Massive Space for Your Creations

Unleash your creativity with a generous build volume of 320x320x385 mm³ (12.59x12.59x15.15 inches).

This sizable printing area allows you to create larger models or multiple smaller objects in a single print, expanding your creative possibilities.

300°C High-Temp Nozzle

The 300°C high-temp nozzle kit features an extended hot end, a 60W ceramic heating element and a brass heating block, capable of printing various filaments including nylon.

The automatic calibration of nozzle PID parameters ensures precise temperature control for stable and consistent printing performance.

Powerful Extruder & Upgraded Hotend

The dual-gear direct extruder features a 5.2:1 reduction ratio for reliable and smooth filament extrusion, weighing only 290g. All-titanium alloy throat pipe enables fast heat dissipation and reduces nozzle clogging. The 60W high-power ceramic heating element and brass heating block provide efficient and uniform heating for quick filament melting even during high-speed printing.

The extended hotend nozzle can withstand temperatures up to 300°C, making it capable of printing PLA, PETG, ABS, ASA, TPU, and high-temp filament nylon. (Tips: ABS and ASA filament materials are recommended to be used in conjunction with a 3D printer enclosure.)

The automatic calibration of nozzle PID parameters optimizes nozzle thermal performance and temperature control, ensuring consistent and reliable printing results.

Versatile Connectivity and Control

Connect seamlessly with our printer using various options including WIFI, U disk, and LAN connectivity.

Enjoy the convenience of WEB remote control printing and multi-machine network printing control for effortless management of your printing projects.

Just start your printing jobs with a one-key file transfer.

The print head incorporates 2x4015 thickened double-sided cooling fans and a 3010 ball-bearing blower fan for omnidirectional heat dissipation and to prevent filament warping or deformation.

The 2x6025 ball-bearing blower fans behind the print head further enhance cooling performance by rapidly cooling the newly deposited layers.

The upgraded dual-sided plate ensures perfect PLA prints with a new specialized PLA Surface for excellent adhesion and minimal warping even at lower heatbed temperatures.

The original Textured PEI Surface ensures strong adhesion and easy print removal, supporting materials from PLA and TPU to high-temp options like ABS and carbon fiber

The Z-axis incorporates dual lead screws, dual motors, and a double tie rods structure to ensure stability and precise layer alignment. The Y-axis features two rows of 3+3V wheels for smooth and stable motion, and a double Y-axis profile design to further enhance overall rigidity and printing stability.

All axes of the printer come with silent drives, ensuring quiet operation. POM V-guide wheels move quietly, smoothly, and accurately. The XY-axis belt tensioner with a hand-twist knob allows for easy adjustment and optimal belt tension.
