  • 【RSG Leveling System】The 16-point RSG leveling system with a strain gauge pressure sensor on the print head to record the distance between the nozzle and the hot bed at each point. Once the sensor scans any tiny variations and unevenness, it will automatically compensate each point by adjusting the Z-axis height to ensure the same distance between the print nozzles and the bed (about 0.1-0.2mm). And Neptune 3 comes with a larger build volume of 220x220x280mm than Neptune 2.
  • 【Reliable Extrusion System】The double-gear metal extruder is designed with a spring elasticity adjustment and a special titanium alloy throat pipe for smoother filament feeding and more stable & precise printing, greatly reducing the risk of nozzle clogging.
  • 【Ultra-Quiet Printing】XYZ axis adopts TMC2225 silent driver and E0 axis of TMC2209 silent driver, which ensures more stable and smooth movement at a whisper-quiet below 50dB. V-guide roller made of POM for stable and accurate motion, quieter, wear-resistance, and longer life.
  • 【PEI Magnetic Platform】The PEI spring steel magnetic platform with a special coating features anti-warping and high stickiness, and you can remove printed models merely by bending the steel sheet. With a filament sensor, whenever filament runs out, breaks, or gets clogged, printing will pause until you load the filament and resume.
  • 【Removable Touchscreen】The 4.3-inch removable full-color touch screen can be operated by hand-held or fixed on the base with an intuitive interface and step-by-step assistance, which is more convenient to operate and support multi-language freely switch.

Auto Leveling

Precise 16-point RSG leveling system adopts a strain gauge pressure sensor on the print head to measure the height between the nozzle and the printing platform at 16 points. With just one touch, it will automatically calibrate and compensate for any slight variations and unevenness between the heated bed and the print head, ensuring a consistent distance between the nozzle and heated bed and a perfect first layer printing. 

Double-gear Extruder & PEI Magnetic Platform

The double-gear metal extruder adopts a spring elasticity adjustment device and special titanium alloy throat pipe for more uniform extrusion force, and continuous & stable filament feeding. 

PEI magnetic platform with a spring steel sheet and good adhesion and printed models can easily be removed by bending the print sheet.

Safe and Silent

The 250W hotbed can quickly heat up to 100ºC to meet the needs of different filament materials and avoid warping issues. The branded power supply has been repeatedly verified to ensure safe printing and reduce printing errors. 

The XYZ axis is driven by TMC2225, E0 axis is driven by TMC2209 with more stable motion performance and a lower printing noise of under 50db, like a person's whisper.

Stable Metal Constructure

Solid metal frame with a portable handle and overhead gantry for maximum stability during printing for better overall print quality. V-guide roller made of POM with smooth movement, low noise, and wear resistance. 

The XY axis adopts the belt tension adjustment device with a hand-tightening nut to conveniently and easily adjust the belt tightness.

Smart Resume Printing

No worry about unexpected power off as the printer can recover from the power outage and continue printing. With a filament sensor, whenever there are possible accidents like filament runout, filament breakage, or filament blockage, the machine will stop work for resuming printing before the new filament feeds in. 

Neptune 3 also comes with a guide wheel structure to reduce the feeding resistance of consumables and noise generation.

More Features

The larger build volume of 220x220x280mm gives you more freedom to produce larger models or carry out batch printing. 

A removable 4.3-inch color touchscreen with a multilingual intuitive interface and smooth touch controls by hand or fixed on the base, giving you a user-friendly operating experience.

Double-sided cooling fans with a more reasonable nozzle heat dissipation structure, which automatically shuts down after the nozzle is lower than 50 degrees, reduce fan noise, and prolong the service life of the fan.
