ELEGOO Neptune 4 Max: Speedy XXL 3D printer

Elegoo Neptune 4 Max 3D printer

The ELEGOO Neptune 4 Max is the most important 3D printer that I reviewed. With an enormous 420*420*480mm construct quantity, you’ll be able to print huge 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 complicated open-source 3D printer software program developed by KevinOConnor that permits you to print sooner and extra precisely than Merlin or others.

I’m not a 3D printer knowledgeable like Uncle Jessy, so this assessment is written extra from the attitude of a regular consumer who commonly prints all types of issues wanted round the home. I primarily use PLA and TPU filaments, however some useful components require stronger CF filaments with the next 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 aspect with a brass heating block to permit as much as 300 °C nozzle temperature.

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

Neptune 4 Max 3D printer assessment

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

Thick foam padding for extra protection

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 in the course of the transport, however fortunately, due to the thick foam padding, the printer remained intact inside. Once I confirmed the bundle had arrived, they despatched me the most recent firmware information and directions on upgrading the machine.

Included tools and accesories

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 baggage and IKEA-style printed step-by-step meeting directions, ELEGOO offers a video information on the USB stick.

Front and side view

The machine consists of two major components (base unit and Z-axis gantry) that you could assemble utilizing the included screws and instruments. Two further aluminum tie rods are on the again for the Z-axis gantry, which makes the construction extra stable. 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 straightforward wiring. In entrance, there’s a small drawer to retailer upkeep instruments and spare nozzles.

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 characteristic is a must have for large-scale 3D printers, the place you typically want to make use of a couple of 1kg spool to complete the challenge. 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 suggests it would 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 aspect with a brass heating block, three cooling followers, a 0.4mm nozzle, and an auxiliary LED mild. 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.

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

It takes a number of good minutes until the mattress reaches 60 °C, which is required by PLA and different kinds 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 :).

One of the six leveling knobs

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

Along with handbook mattress leveling, the Elegoo N4 Max options 11×11 automated mattress leveling (ABL). To examine 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 recognize this printer is far sooner 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 in line with Elegoo, it may possibly go as much as 500mm/s. By comparability, my present printer’s pace may 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 number of assessments at varied speeds. I observed that growing from 125mm/s to 250mm/s doesn’t scale back the job time by half as you’d anticipate. The identical occurred after I elevated the pace from 250mm/s. The general run time turns into shorter however not twice as quick. As an alternative, I observed seen high quality degradation at larger speeds -of course, this will likely fluctuate in line with 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 observed that at excessive speeds, it’s vulnerable 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 prime pace is that transferring components comparable to belts, bearings, rails, and rollers will put on out a lot sooner 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 fitting aspect is an RJ45 connector for wired connectivity and a tiny rubber ducky antenna for the wi-fi WIFI controller. The print information may be loaded into the machine by way of a USB port from a reminiscence stick or remotely by way of an internet browser.

Klipper Fluidd web interface

The Fluidd internet interface may be accessed by the IP tackle assigned by your own home router. Apart from gcode file add, the net UI offers distant management over the machine, permitting to regulate parameters comparable to:

  • Motion Management: management the motion of every axis and may 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 sizzling mattress temperature may be set prematurely.

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

Pricing, availability, and choices

Beginning in September 2023, the Neptune 4 Max may be ordered from Elegoo’s official retailer for $470 or from their Amazon retailer. For sooner order processing, they’ve six regional warehouses (US, CA, AU, JP, UK, and EU). In response to your location, as a result of restricted shares and excessive demand, the bundle 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 comparable to wearable cosplay masks or ornament gadgets, the Neptune 4 Max is the most effective bang on your buck 3D printer, round $500. It’s also nice for individuals who need to print a number of gadgets concurrently. By comparability, you’ll be able to print not less than 100 little buddhas concurrently on the N4P (40x40cm) or 32 ones on a regular 23x23cm machine just like the N3Pro. The wonder is that, as a result of larger printing pace, the 100 prints will probably be executed similtaneously utilizing two or three 50-100mm/s machines.

Control panel of N4 Max

I can’t lie that the Neptune 4 Max is for everybody. The big construct quantity comes with its issues. First, you’ll need a devoted room for this printer and a technical rack for set up. Common workplace desks that do not need de obligatory dimension. Putting in it in a residing house will not be an choice as a result of noise this machine makes on high-speed printing. The massive 40x40cm heated mattress requires extra power and time to warmth as much as the specified temperature than common 23x23cm platforms. Throughout summer season, in small areas, the 320W heating aspect will increase the room temperature, requiring extra cooling.

Construct Ideas

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

Bild tips

  • 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 aren’t caught below the screws or in the way in which 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 rigidity, and curler wheels once more, then repeat the leveling course of.

Find out how to improve the firmware on the Neptune 4 Max?

Being a brand new mannequin, firmware improve information aren’t out there but on the Elegoo obtain part, however you’ll be able to request them straight 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 recognized points.
