Should I Buy It?
If you're technically inclined, patient with setup and maintenance, and in search of high print quality at a reasonable cost, the Neptune 4 could be a fantastic choice. However, beginners or those looking for a more hands-off printing experience might want to consider alternative options that offer easier setup and less ongoing maintenance.
It does its job well. The bed leveling process isn't too hard, but it is not fully automatic. There are a few manual steps to get the nozzle at the correct height at the center and near the 4 corners. Then it automatically does a more detailed map throughout the bed. The four adjustment knobs for the four corners are rather easy to turn, without a way to lock them in place, so over time they will likely drift and have to be readjusted. You want to do a bed leveling every time things may have changed such as if you've moved the printer, you have done a number of prints, or it has been some time (like several days) since your last print just to be safe. I once tried to pause a print and then move the printer, but after resuming, the print fell apart, and the printer was basically extruding spaghetti. So I would say it is best practice to let an entire print run undisturbed. I would have the same patience for this printer as I would a washing machine, rather than a paper printer. It is loud, particularly the fan that cools each layer. On top of the smell, it is not suitable to keep and run in my small room. I was even worried about the noise disturbing my neighbors when putting the 3D printer in the living room, so I moved it to our laundry room. This is my biggest complaint for this printer. I also would have liked the holder for the filament spool to be more sturdy. For the most part, it is user friendly. You just need to follow a video to set it up. Then you have to learn about the best print settings for making your .gcode files the included Cura software. I decided to have most of my prints set to 0.2 mm layer height, 20% cubic subdivision infill with supports and brim. The parts that I print tend to have small features of a few mm, so those areas will be nearly 100% infill due to the 3-layer shell. I have yet to run the printer at 500 mm/s. A typical speed is more like 200 mm/s, and the prints more complex parts that are a few inches in size and about 30 grams in 1 hour, whereas smaller simpler parts like 1/2" cylindrical spacers or small gears are done in 10 minutes. Hole diameters are not always accurate to 0.2 mm, and may be off (usually smaller) by as much as 0.5 mm. If it's a small enough hole, then I easily solve this by using a drill bit. I was able to do this for holes as small as 1 mm, but should be possible for even smaller holes. For larger holes, I have tried filing, sanding, using a deburring tool, and even a knife, but this is more labor intensive is easier to just reprint the part. Any hole whose axis of symmetry is horizontally-oriented will turn out to be more of an ellipse, and the supports take some effort to get out. If you're making smaller parts like me, such as mounts for PCBs or gears and adapters for micro servos, then I would recommend getting a set of M1.7 to M3 self tapping screws, as those have proved invaluable for assembly, although you have to be careful not to tighten too much and strip the hole you tap.

this is the first Commercial FDM printer I I have purchased. My other three I built myself. I’ve been into 3-D printing for a while now and I am very impressed with this machine. It basically comes in two pieces that you screw together. Pay attention to where your wires are. The connectors are pretty straightforward. Had it up and running in one hour printing 300 mm/s For fun. Be sure to use high-speed PLA plus when going fast can’t tell the difference in quality when printing at 1/5 the speed. Pretty amazing, Have had zero problems after five prints And counting. Printing with a layer height of .16 mm on the finish is impressive to say the least. It was printing so fast I thought it was definitely going to skip steps, But it just kept on Truckin. Can’t beat it for the price if you need an FDM grab one of these. It has everything you need, Auto bed level, Removable print bed, Direct drive extruder, Print cooling fan bed cooling fan, Ability to adjust settings while printing. I can only find one drawback, and that is the fan noise can be quite loud, especially when using the larger set of fans. But you only need that when you are printing super fast and need that layer to cool to be ready for the next.

I've had this printer since March 24th 2024. I also have Elegoo's laser cutting product as well. I'm going to break down my personal experience with the Neptune 4 product. This is a honest review based on performance issues. That being said, please take note if you're planning on purchasing this exact model. This in no way reflects on other models in their lineup. I can only give an opinion on the Neptune 4. This unit is extremely problem plagued. If you own one of these, or you're planning on purchasing one, if you go searching for help through Reddit posts, the official Elegoo sponsored videos involving the product, reading the literature involving this exact model, you will find nothing but excuses for this machines terrible performance. What's concerning here, and the reason why I'm taking the time to write this long review, is the small consensus of people who make nothing but excuses for this machines poor performance and failure rate. When you first start out and you start running into these problems, you'll find that this small but noticeable presence on the internet seems to like to blame the owner by pointing out that they just aren't adjusting things right or they aren't following procedures correctly or they are not cleaning the bed correctly or they're not leveling it properly or they're not making sure the belts are tight but not too tight or they're not making sure the G-Code isn't properly written or they're not making sure the PLA spools are properly stored or Cura slicing software is to blame (the only one officially offerd by Elegoo) . The list of "victim" blaming here goes on and on. It's seems to always be everybody else's fault except Elegoo's in the machines performance. I'm here to tell you firsthand, it's the machine. Granted, there is a learning curve to this machine as with any 3D printer. They can be very particular but that doesn't cover the poor quality of this unit and his performance issues. When it comes to their software backing, this is where I think a lot of the issues lie. If you don't believe me and if you own one of these things you know what I mean. Just go over how you have to take care of the bed mesh issue in the software. There's been no fix for this either in any of the updates for this machine. That is another issue considering the flawed software issues with Kippler as its operating system, or possibly the Moonraker software that enables it to talk to The Host computer, or any of the issues in between. There's almost no patches or fixes for the issues that they have to know exist by now. You are going to experience, at least with this model, more downtime and wasted material and parts than you will have successful prints. To say that this machine is frustrating is the understatement of the year. There are times I have really thought about just buying a new machine and just throwing this one away. In the long run it would be cheaper. I'm writing this article today due to the fact that I have had the print bed belt snap out of nowhere. I keep this machine properly maintained. That is important when considering these machines, you have to spend the time to keep them in great condition. With this model it doesn't seem to matter how good of care you take of it, it's going malfunction on you regardless. They're definitely seems to be an issue between the hardware and the software and it's very noticeable at times and I have yet to see anyone make actual fixes other than excuses. Before I get attacked by naysayers, yes I have deleted the firmware, updated the firmware more times than I can count. Have I done the general maintenance as described by the company? Religiously. Have I taken the time to learn what is going on when it comes to the problems as according to the company's own sponsored YouTube videos on how to repair things like the glob of death? Oh wait yeah that's another issue that they have no fix for, you just have to go through all the 20 steps to fix that issue after you've spent hours researching why the MACHINE NOT THE USER is wasting material print after failed print. This is not a cheap entry model printer that you're supposed to tinker with before and during every single print but that's what this is. In this price range it is unacceptable. I could go on and on about this printer's issues, and it's only the Neptune 4. Again, I cannot speak of any other of Elegoos products for I only own the two products listed at the start. At this point, I don't know what bothers me more, the company's disregard for serious patches to correct the software issues in this machine, and or parts that I've had to buy on my own that should have not been placed on this machine due to poor quality or a small number of community members online that consistently make excuses for a machine that needs to be recalled whereas it makes the user of the Neptune 4 feel like they're consistently always doing something wrong to cause the consistently horrible bad prints or failures. This is not something I wanted to spend an hour of my day writing and have contemplated for months even writing this review but with Christmas time here and people wanting to purchase this for their family members or themselves, if I could save at least one family from the frustrations of this particular model then it was worth the time it took to write this review. I need to restate that this review is only towards the Neptune4 and not Elegoo's overall product line up. Update 12/13/24. I have decreased my rating from a 2 star to a 1 star. I reached out to their customer service. Keep in mind this product is under its year warranty. Not much of a surprise here but that warranty means nothing. Unless you return it back to Amazon in the 30 day window, you won't actually have a usable "warranty ". Elegoo's customer service does respond but will lead you on a weeks long endless copy and paste response waste of time that leads no where. You soon realize after a week of providing them photos, logs of the machines settings and printing stats, hours of you detailing your experiences, that it is of no avail. It seems like they're more interested in just data harvesting your info then actually helping and or providing any type of replacement or repair. You definitely get the feeling towards a week-long of Correspondence that they never had any intention of helping. I can't emphasize this enough, avoid this company in general if this is the customer service they have for the support of their product base. My original statement was based only on the Neptune 4. I gave that company the benefit of the doubt in the beginning because I originally had issues when I first got my laser cutter as well which never got resolved, and I had to fix myself by replacing a faulty power supply that almost caused a fire in my house. After hours worth of documentation including video footage of what happens when the power supply would glitch and cause a laser to get stuck in 100% on position and not move, just to never hear back from their company. This should have been my foreshadowing of upcoming events with this company. The original article that I wrote never stated anything about the issue I had with their other products. But so far the two products that I own from them have failed miserably and they obviously are not going to stand behind their products. So I change this from a two-star to a one star. If I can leave it at a zero I would. I can leave this advice to any consumer that has read this entire article, I appreciate you reading all of this, thank you, please avoid this company and their products you will be extremely disappointed and will be wasting a lot of money when there's plenty of competitors out there that will stand behind their products. This company will not support their products and I think I know the reason why. If my experience is any type of slice of window into their overall product lineup they wouldn't be able to maintain profit having to repair their poorly designed machines. This company obviously puts profit well above customer satisfaction in the worst, most frustrating way I've ever personally had to deal with in many years. Save yourself the time, disappointment, and money from dealing with this company.
