Elegoo Neptune 4 Max 3D Printer Review Experience Issues & Solutions

The Elegoo Neptune 4 Max is a new FDM 3D printer that has been released earlier this year in 2023 and of course it’s a large-format 3D printer with a build volume of 420mm x 420mm x 480mm, and it is capable of printing at speeds of up to 500mm/s which is a big leap in 2023 from the performance of previous high-end 3d printers. The Neptune 4 Max also features a number of other features which just place it on the top in the ranks and that also make it a compelling option for both beginners and experienced users.

First of all we would start with the cooling fan as pretty much everyone throw questions about that much often. So to cool off prints as it throws down filament quickly, the printer has a massive fan unit on the back. It could sound loud for some, but you can potentially disable it if you want to. The printer also has Wi-Fi built-in, making it simple to set up on the touchscreen unit, connecting to your network. Using slicers like Orca, you can wirelessly send sliced files directly to the printer, with fast file transfer speeds. The most important detail—the pricing for this machine—is $470, just under $500 for this massively huge, fast 3D printer.

Here are some of the improvements that we have seen in Neptune 4 Max

Here is the video review of Neptune 4 Max


Here are some of the key features that make this 3d printer ideal for everyone:

i) Auto-leveling
ii) Large build volume
iii) High print speeds
iv) Direct drive extruder
v) Klipper firmware
vi) Heated build plate
vii) Printing Speed

i) Leveling

When it comes to leveling its massive print bed, there are six wheels on the bottom for manual bed leveling, along with 121 points of Auto bed leveling. There’s some contention around this, with a preference for printers with wheels for more precise adjustments. The printer has a direct drive extruder with a custom 0.4 mm nozzle, allowing for fast prints, is n’t it great?

This printer Neptune 4 Max uses a BLTouch sensor to automatically level the print bed before each print, ensuring a good first layer and reducing the need for manual bed leveling. We have explained it in detail below.

ii) Large build volume

Basically it’s a large machine that might be challenging to find a location for when it’s up and printing. You would need much space while working with a large 3D printer like this. It would definitely allow you to print at a much faster speed than the older Neptune 3 Max.

The big difference between the Neptune 3 Max and the Neptune 4 is the difference of time while printing. But there are some other key differences between them, like the build volume. The X and Y build volume is the same, but the vertical build volume is slightly smaller due to the new larger fan-built system to keep everything cool while printing extremely fast. The build volume on this is 420 by 420 by 480 mm—just a massive build volume for a 3D printer.

iii) Direct drive extruder

You would notice it uses a direct-drive-extruder, which provides better filament feeding and retraction than a bowden extruder. This makes it ideal for printing with flexible filaments and other materials that can be difficult to print with.

iv) Klipper firmware

Klipper firmware is an other great step in this line of 3d printers as this one comes pre-installed with Klipper firmware, which is a high-performance firmware that offers a number of advantages over Marlin firmware, such as higher print speeds and better input shaping so it pretty much gives us edge over everything.  One of the great things about these new Neptune 4 3D printers is that they come pre-installed with Klipper which has pushed the boundaries for this printer by enabling faster 3D printing. It also enables some other key features. On the Neptune 4 Max and the Neptune 4 Plus, there are no X and Y end stops which would ease the job out. Initially confusing for everyone, but a firmware update addresses any grinding noises during the process.

v)  Heated build plate

It also comes with a heated build plate that can reach temperatures of up to 110°C, making it possible to print with a wide variety of materials.

vi) Printing Speed

Speaking of printing fast, this machine can go up to 500 mm per second. In reality, you’re more likely not going to be printing that fast and trying to get really good quality prints. You’ll probably be printing somewhere around 150 to 300 mm, which is still insanely fast compared to the older iterations.

vii) Printing Experience

Now, we were going to use it, the first thing we noticed on this 3D printer a Benchy that was pre-sliced with the printer and it just came in at 28 minutes. Well it could or that might not be the absolute fastest Benchy that we have seen thrown down on a 3D printer, this was just a standard Benchy. It was like the Ware that has no infill or anything like that. This is just a standard Benchy that they have sliced, we think with the Elegoo Cura version of their slicer for such a big printer for much prettier results.

But what we realized while running our first initial prints is the print quality that we were getting after the first run. So, that was our very first set of prints that we printed on Neptune 4 Max machine, and overall, the prints were looking pretty decent. This was using the Elegoo Cura, just the default profiles there, and again, the prints were looking pretty good. Though we end up running into some print issues or print failures with the support settings on some of the earpieces. These are kind of tricky parts to run off in 3D print and to have stabilized and not knock over when they were printing. So, we are reprinting those one anyways, but it’s a greater 3d printer.

But what made us wonder was the faceplate the silk-looking one that you would see. Well, transitioning filament  came out pretty nice. And then I went off and reprinted it in Elegoo’s new gold silk PLA. That is a really nice vibrant gold that we think is a good match for anything you want to print. Unfortunately, we had just slight layer shift that looked like it was a very small faint layer shift right in the center of the faceplate there. So that was the issue that we faced but we are going to take care of it. It’s just the beginning.

We also went off and tried to print other model variations of it. But again, this is with the Elegoo Cura, and we were just having so many issues with the tree support settings off of that Cura version there. So, we stopped running that but this is just an experience of some of the things that we printed and ran into issues. Gradually, we will cover everything and get over every single issue. As we printed several tiny parts and everything else just came off very beautiful and of course the time it takes to print is way lesser than the Nepture 3 series 3d printers. So this is just the right product for everyone and it just is affordable.

With these features this 3D printer from Elegoo is much better and faster one. This is the new Neptune 4 Max 3D printer which we use to 3d print large amounts. It’s not going to break the bank to pick one up and will up your game when it comes to 3D printing things like large cosplay props. Since 2022, Elegoo has released an update across their entire lineup of the Neptune series of 3D printers and they have also improved on their Series 3 printers with the Neptune 4 3D printers, which are the smallest options available. They now have the Neptune 4 Plus 3D printers and the massive one–Neptune 4 Max, is a new, faster power-packed release of the Neptune 3 Max lineage.
