The ELEGOO Neptune 4 Max is the biggest 3D printer that I reviewed. With a large 420*420*480mm construct quantity, you’ll be able to print large fashions directly with out the necessity to glue a number of components collectively. The Klipper firmware may even be a primary for me. Klipper is a sophisticated open-source 3D printer software program developed by KevinOConnor that lets you print quicker and extra precisely than Merlin or others.

I’m not a 3D printer professional like Uncle Jessy, so this assessment is written extra from the attitude of a typical consumer who often prints all types of issues wanted round the home. I primarily use PLA and TPU filaments, however some purposeful components require stronger CF filaments with a better melting level. Most entry-level 3D machines attain 260° Celsius, which is inadequate for industrial-grade supplies. The Neptune 4 Max’s hot-end has a 60-watt heating factor with a brass heating block to permit as much as 300 °C nozzle temperature.

Final 12 months, I examined two fashions of the Neptune 3 sequence, which additionally had three construct quantity choices. Along with the upper nozzle temperature and quicker printing pace, the operation system is probably the most vital distinction between the Neptune 4 and three sequence. The N3 runs on Merlin, and the N4 runs on Klipper. Because of the superior cooling system put in behind the print head, the construct quantity of the Neptune 4 sequence is barely smaller than its predecessors – the Z-axis is shorter by 1.5-2cm.

Neptune 4 Max 3D printer assessment

I obtained the Neptune 4 Max final week. ∞Elegoo moreover included a 1 kg spool of PLA check filament. I obtained a pattern unit from the primary batch that arrived in Europe, so I can not assure that you’ll get a product that performs the identical as in my article.

Once I noticed the large field (79x69x27 cm), I noticed it was not an workplace desk printer. It’s an enormous and heavy machine. The cardboard packaging crumpled fairly badly throughout the transport, however fortunately, because of the thick foam padding, the printer remained intact inside. Once I confirmed the package deal had arrived, they despatched me the newest firmware information and directions on upgrading the machine.

Elegoo is concentrated on offering easy-to-use printers out of the field, together with all the mandatory equipment and instruments to be up and run in only one hour from unboxing. Along with the labeled screw luggage and IKEA-style printed step-by-step meeting directions, ELEGOO supplies a video information on the USB stick.

The machine consists of two predominant components (base unit and Z-axis gantry) that you will need to assemble utilizing the included screws and instruments. Two additional aluminum tie rods are on the again for the Z-axis gantry, which makes the construction extra strong. The print head, cooling unit, and spool holder additionally must be put in by the consumer. All of the connectors and sockets are labeled for simple wiring. In entrance, there’s a small drawer to retailer upkeep instruments and spare nozzles.

Large measurement. Not an workplace desk 3D printer

The photograph beneath reveals the numerous measurement distinction between the Neptune 3 Professional and the Neptune 4 Max. You will have about 100x90x75cm (HxDxW) area to function this machine comfortably. The 3D printer itself measures roughly 658x632x740mm and weighs greater than 18kg.

Along with the highest LED bar that illuminates the whole print space, it has a further LED on the print head that instantly illuminates the nozzle that may usually be in shadow.

Filament run-out sensor and power-loss restoration for enormous prints

A filament run-out sensor is included within the field and must be put in on the highest between the filament spool and the print head. This function is a must have for large-scale 3D printers, the place you usually want to make use of a couple of 1kg spool to complete the mission. For instance, a Mandalorian Helmet with helps requires 1450 grams of fabric and shut to 2 days to print. The Neptune 4 Max additionally options power-loss restoration, which implies it’s going to proceed the print job after energy is recovered.

Neptune 4 Max: Print head

The print head on the Neptune 4 Max consists of a proximity dual-gear direct driver extruder, a 60-watt heating factor with a brass heating block, three cooling followers, a 0.4mm nozzle, and an auxiliary LED gentle. To deal with as much as 300 °C temperatures, it makes use of an all-titanium alloy throat pipe.

The print head attaches to the Z-axis utilizing three screws from the again and two from the entrance.

Once I loaded my filament for the primary time, and it began to purge, a unique colour materials got here out, proving that Eleggo examined the unit earlier than delivery it out.

Neptune 4 Max: Heated print mattress with PEI sheet and 121 factors ABL

It takes a couple of good minutes until the mattress reaches 60 °C, which is required by PLA and different sorts of filaments. Whereas I used to be ready for the printing to begin, due to the loud noise of the followers, I had the sensation that I used to be sitting in a aircraft with all of the generators on, ready to take off :).

The heated platform measures 420x420cm (usable space) and has a 320W heating factor and 6 leveling knobs beneath. The PEI sheet is just like those used throughout the Neptune 3 and Neptune 4 sequence. Most filaments follow it nicely, and eradicating the mannequin is simple; you might want to bend it a bit, and it’ll pop off.

Along with guide mattress leveling, the Elegoo N4 Max options 11×11 automated mattress leveling (ABL). To verify and compensate for the flatness of the platform in all 121 factors takes a couple of minutes. Word: DO NOT run ABL with out the PEI sheet!

Neptune 4 Max: Is that quick?

Sure! If you put it to work, even with closed eyes, you understand this printer is way quicker than most hobbyist machines. It makes a noise like a hardworking bee on steroids :). The auxiliary cooling unit additionally provides extra noise to the system, making it very loud.

By default, the printing pace of the Neptune 4 Max is ready to 250mm/s, however based on Elegoo, it could possibly go as much as 500mm/s. By comparability, my present printer’s pace could be adjusted between 50 and 180mm/s. From the N4 Max’s management panel, you’ll be able to toggle between three working modes (Silent, Regular, and Sport) and alter print pace inside 0-500%.

I did a couple of assessments at numerous speeds. I seen that growing from 125mm/s to 250mm/s doesn’t cut back the job time by half as you’ll anticipate. The identical occurred once I elevated the pace from 250mm/s. The general run time turns into shorter however not twice as quick. As an alternative, I seen seen high quality degradation at larger speeds -of course, this will likely range based on the complexity (geometry) of the printed mannequin. To work on 250-500mm/s additionally requires extra correct mechanical changes (leveling and belt tensioning).

Throughout my assessments, I seen that at excessive speeds, it’s liable to layer shifting. In my view, max pace is nice for prototyping, however not if you happen to favor high quality.

One other factor nobody talks about when printing at high pace is that transferring components similar to belts, bearings, rails, and rollers will put on out a lot quicker than doing it at regular pace.

Neptune 4 Max: Connectivity and file switch choices

Elegoo’s newest large-scale 3D printer additionally excels when it comes to connectivity. On the suitable aspect is an RJ45 connector for wired connectivity and a tiny rubber ducky antenna for the wi-fi WIFI controller. The print information could be loaded into the machine through a USB port from a reminiscence stick or remotely through an internet browser. The net interface could be accessed by the IP tackle assigned by your house router. In addition to gcode file add, the net UI supplies distant management over the machine, permitting to regulate parameters similar to:

• Motion Management: management the motion of every axis and might set compensation after leveling
• Fan and Output: management to activate the printhead fan and lighting
• Printer Restrict: the utmost acceleration management of the printer
• Temperature Show: show the machine temperature heating situation, and the preheating printhead temperature and scorching mattress temperature could be set prematurely.

The Neptune 4MAX additionally has a Sort-C port to attach it on to your laptop utilizing a USB cable.

Pricing, availability, and choices

Beginning in September 2023, the Neptune 4 Max could be ordered from Elegoo’s official retailer for $470 or from their Amazon retailer. For quicker order processing, they’ve six regional warehouses (US, CA, AU, JP, UK, and EU). In keeping with your location, as a result of restricted shares and excessive demand, the package deal will probably be shipped out in November or December. The N4 Max can also be out there in combo packs with included 1KG or 2KG filament.

Elegoo Neptune 4 Max: Who’s for?

If you wish to print massive objects similar to wearable cosplay masks or ornament gadgets, the Neptune 4 Max is one of the best bang on your buck 3D printer, round $500. It’s also nice for individuals who wish to print a number of gadgets concurrently. By comparability, you’ll be able to print no less than 100 little buddhas concurrently on the N4P (40x40cm) or 32 ones on a typical 23x23cm machine just like the N3Pro. The sweetness is that, as a result of larger printing pace, the 100 prints will probably be performed concurrently utilizing two or three 50-100mm/s machines.

I cannot lie that the Neptune 4 Max is for everybody. The big construct quantity comes with its issues. First, you will have a devoted room for this printer and a technical rack for set up. Common workplace desks that don’t have de vital measurement. Putting in it in a dwelling area isn’t an possibility as a result of noise this machine makes on high-speed printing. The large 40x40cm heated mattress requires extra vitality and time to warmth as much as the specified temperature than common 23x23cm platforms. Throughout summer time, in small areas, the 320W heating factor will elevate the room temperature, requiring extra cooling.

Construct Suggestions

I assembled it on my own, however at some phases, two additional palms would have been useful, contemplating the dimensions and weight of the tools. I additionally made some rookie errors regardless of that’s not the primary 3D printer I put collectively.

• Earlier than assembling, watch the construct tutorial video included on the USB stick.
• Set up the printhead solely after the Z-axis gantry is hooked up to the bottom unit. I discovered
• Don’t over-tighten the screws from the start.
• Test that the cables will not be caught below the screws or in the best way of the transferring components.
• Calibrate the print platform manually earlier than auxiliary ABL.
• Don’t panic in case your first print fails. Test all of the screws, belt pressure, and curler wheels once more, then repeat the leveling course of.

The right way to improve the firmware on the Neptune 4 Max?

Being a brand new mannequin, firmware improve information will not be out there but on the Elegoo obtain part, however you’ll be able to request them instantly from the producer. Mine arrived with firmware V1.2.2.26, and I up to date it to V1.2.2.34 that premise to repair some identified points. After upgrading the firmware, the WIFI stopped working, producing new issues, too.

Upgrading the N4Max consists of two phases; first, you might want to replace the firmware of the machine after which the software program of the LCD management panel.

1. Important Management Firmware and Machine Configuration Recordsdata:
   • Copy the “ELEGOO_UPDATE_DIR” folder into the basis of a USB stick
   • Insert the stick into the Neptune 3 Max’s USB port
   • GO to the settings menu and choose the “Data” (About machine) tab
   • Click on the improve button arrow and ensure the firmware replace; after ending, the system will reload
2. Contact Display Firmware Replace
   • Copy the “UI_4&4Pro-Common” *.tft firmware file on a micro SD card (prior format it FAT32)
   • Energy off the 3D printer
   • Take away the again cowl of the LCD management unit and cargo the micro SD into the TF slot.
   • Energy on the 3D printer, the display will present a standing bar of the improve course of.
   • When completed, restart the machine.
