Anycubic I3 Mega-s Review

Posted on  by admin
  • Anycubic i3 mega S is one of the popular low end 3D printers that provide a good performance price ratio.
  • It is easy to install, very user friendly and works out of the box without too much configuration.
  • The Anycubic i3 mega S is ideal as a first 3D printer and I highly recommend it.

The i3 mega S it is the updated version of the older i3 mega printer launched a few years ago. The biggest change is probably the filament holder. Other than the i3 Mega S, Anycubic has a few other printers to cover other segments of the marked.

The prices start from around 180$ for the Photon Zero and Mega Zero to about 400$ for Chiron. The price seems to be directly proportional with the printing area.

It arrived in the Netherlands from Czech republic in 4 days with DHL. Interestingly, since I’ve ordered the printer with two filaments included, the filaments arrived with a separate shipping, a day later. However, the printer had a few grams of blue filament, so I could test it in the first day.


Other than the printer, the package comes with a few accessories and spare parts. The most important is probably the replacement nozzle and the spare limit circuit. There is also an installation guide in English.

Installation is very easy since the printer has only two main parts: the base with the CPU and the Z-axis bar. There are three screws on each side to keep these two components together. The most complicated step is probably the base levelling and calibration.

Use cases

The installation manual takes you to all the steps, but basically you need to lower the base (tide up the calibration screws) and take the nozzle to Z position. Then move the base and the nozzle manually back/forth and left/right to check the distance on the whole surface.

As the manual says, use the provided paper inbetween the base and the nozzle to prevent scratches. When the printer is ON, the nozzle and the base do not move freely by hand, so you have to turn if OFF.

You want the distance between the nozzle and the base to be equal everywhere. As a guide, you should be able to move the paper on the base with a bit of friction. Very important is to lower your base midway before your calibration so you have space to adjust it.

Technical specifications of Anycubic i3 Mega S

As a last step, you have to insert the filament. Push it all the way through, until it gets to the nozzle. As many people recommend, you should upgrade the firmware to Marlin 1.1.9 (the download link is on the top right corner). This new firmware comes with some cool features that you can find on the link.

With the stock printer, you should use the hex file Marlin-Ai3M-v1.4.6-stock_drivers.hex. I used Ultimaker Cura to upload the firmware and Pronterface to run the needed commands.


Some commands do not return any answer, but that is fine. You might think the firmware update is not working because the firmware version in the menu still says v1.1.2. That version is for the panel firmware and has nothing to do with the printer firmware.

If you updated to Marlin, then you should see more functionality in the build menu. The printer comes with an SD card with the 3D model of two owls. This model will be enough to get you excited if this is your first printer and to check that your printer is calibrated properly and works fine.

This slideshow requires JavaScript. After about one hour of printing, if everything goes fine, you will end up with the owl couple printed. The models will be very easy to unstick if the base is cold, so make sure to wait until the base cools down to about 30 celsius!

I think the quality is pretty good and considering that I have not done any adjustments or advanced calibration, so I am quite impressed by the result. I’ve found the blue filament that came with the printer to be very dry and it broke by itself in multiple pieces when the temperature changed in my room.

However, the two filament rolls that I’ve ordered are more flexible and work perfectly. Ideally, you should store your filaments in air tight bags with some a silica gel bags inside to absorb the humidity.

Anycubic i3 Mega S Review Verdict

Considering that Anycubic i3 mega S is my first 3D printer, I am very pleased about the purchase. The other candidate I was looking at is Creality Ender 3 Pro, but after hours of online research I went for the mega S.

There are plenty of comparisons online and from what I’ve read, these two are very similar in terms of capabilities, as well as price. If you are planning to buy this printer, I recommend you to get the package with one or two filament rolls included. You basically get them at 50% price, so a very good deal.

Anycubic i3 Mega S Technical Specifications

Disclaimer: I have not been in contact with Anycubic about this article, nor I have been paid in any ways for writing this. The Anycubic i3 Mega S is the upgraded model from the i3 Mega. Whilst we haven't tested the original i3 Mega vs Mega S, Anycubic has told us that the i3 Mega S upgrades include a mechanical filament sensor that is able to detect when your filament is running low.

A newly designed extruder which will now handle TPS filament and some other useful features such as power recovery loss have also been included. The Anycubic i3 Mega S was delivered in a large cardboard box which was very well packaged. Every component was snugly held together with polystyrene foam.

Upon opening the box, I was pleasantly surprised with all the added extras that it came with:. Toolset (tweezers, unblocking needle). PLA filament (1kg!). I was most impressed with the amount of filament that was provided..a whole 1KG spool of white PLA - the most amount I have ever seen included free with a printer.

A fully constructed spare hotend was also provided which was also a nice added extra. A quick flick through the manual filled me with confidence that the construction of the printer would be a breeze as the manual appeared to be very well written with helpful diagrams.

Let’s hope my assumptions were correct. Very quick assembly - 20 mins max. Sturdy, well-built aluminum frame. Exceptional heated print bed. Fantastic print quality. Easy to navigate touch screen. Lots of extras included. Lead screws for Z-axis.

The extruder is quick to heat. Easy manual leveling. Loud motherboard fan. The bright touch screen is not dimmable. Long filament feed (Bowden setup). The filament can sometimes be tricky to remove. Overall, I have been very impressed with the Anycubic i3 Mega S and considering its a "budget" printer, it has exceeded expectations.

Having used it every day for the past three weeks I am happy to say I haven't seen a failed print yet. This is more than what I can say for the Prusa I3 MK3s which is my go-to everyday printer. The main feature that stood out to me was its heated print bed.

I honestly believe it's one of the best print beds that I have used. The adhesion I have experienced thus far has been nothing short of amazing. The easy to use touch screen was very responsive and becomes simple to navigate once used a couple of times. Impressive print accuracy is achieved through a sturdy aluminum frame which also lends itself well to print mobility should you ever need to move your 3D printer.

The newly updated filament sensor works as it should, and alerts the user with a loud BEEP and will pause the print should your filament start to run low. To load filament into the machine, the user must feed the filament through the senor which is positioned at the bottom right of the machine.

Be warned though, should the end of your filament not be cut at a sharp angle, you will have problems feeding it through. The SD card reader is mounted on the right side of the printer, right next to the filament holder which can make it tricky to access.

Not a major issue, but it would be nice to see it moved to the other side or to the front in a future upgrade. The preheat feature is one that I have used many times and the speed in which the extruder heats up is very impressive. Overall, the time it takes from switching the printer on to actual printing is very quick.

This is due to a combination of things such as the lack of automatic leveling that you get with more expensive printers such as the Prusa i3 MKS. Yes, automatic leveling is a great thing but it will add time to the start of each print. This, combined with the short heating time and a very adhesive bed (less time spent reprinting after failed first layers) means that you can go from a cold printer to printing those first layers in around 2-3 mins.

So far, I haven't had to re-level the print bed since the day I started printing. The Anycubic i3 Mega S is a fantastic printer and can offer hours of fun at a remarkably low price. This printer is a serious contender in the budget printer market and I expect to see Anycubic’s reputation gain some serious points within the 3D printer community.

The team here at Electromaker is really looking forward to seeing what models they release in the future. Use Code: ACELE for $10 off. Printing PlatformStrong adhesive when the platform's hot and easy to remove when cool down. Filament SensorProvides better printing experience of flexible.

All of the Electromaker fun prints were printed with Anycubic’s own branded filament. We found some fantastic models on Thingiverse that we had great fun printing. Everything we threw at the i3 Mega S printed without any issues.

Each model was sliced using the Ultimaker Cura slicing software which is recommended within the printers manual. The test owls came on the SD card provided with the printer.

The instruction manual recommends that you print this file so that you can manually level the print bed using the spring-loaded screws.

The base of the model is perfect for making adjustments to the bed during a live print as the base of the owl model is a rectangle which is slowly filled in meaning that you can observe the layer height being printed onto the bed and adjust the height of the bed using the screws if required.

With Halloween just around the corner and some devilish Anycubic red PLA filament in our print room, the Hell Skull was simply too tempting not to print!

The detail on the facial features and teeth came out very well.

The Apple Watch Stand (inspired by Thing from the Addams Family) has been a major hit in the Electromaker office.

First print

  • It allows you to feed the watch charging cable through the wrist and has space to house the charging disk.
  • Everyone that owns an Apple watch now wants one for their desk.
  • Its a 16hr print so it looks the i3 Mega S will be receiving even more use over the following weeks!
  • Printing this model on a 1mm layer height gave it a really smooth finish and the charging cable fitted perfectly.


  • The wireframe pencil holder has been on my ‘print list’ for some time now.
  • Its a beautiful model which the i3 Mega S printed perfectly.
  • The model requires no supports and stuck to the print bed without the need for any brim.
