The printer’s sheet metal frame provides the rigidity required for frequent use. Even after many months of printing a new line of plastic space commandos or custom jewelry, they won’t snap or warp.

The printing bed built off a revolutionary Anycube composite material evenly heats up and also cools down quickly. This allows for snapping off the finished product with ease.

The 3D printer comes semi-assembled from the box. One has to simply assemble the frame and print bed using the eight screws and three wires to get started. These are available in the packing list.

Always make sure to have the basic tools available for assembling the printer.

The 3D printer’s ambient working temperature ranges between 8 and 40 degrees Celsius, or 46 and 104 degrees Fahrenheit. 

The operating temperature of the extruder at the maximum is 260°C or 500°F. The print bed has an operating temperature of 110°C or 230°F.

These temperatures are fine with filaments like PLA and ABS. With other specialist materials, the temperature has to remain below the maximum range.

This printer’s layer resolution ranges from 0.05 to 0.3 mm, giving you a sense of the level of detail you may expect. This is the thickness of each layer built by the printer while creating your product.

How the printed object turns out depends on the changes in the levels. The thinner each layer is, the more detailed the final output will be. Even with the thickest setting, the i3 Mega’s range is below the typical size of 0.4mm. Thus, the end results come with amazing details.

Nozzle accuracy for z-axis positioning is 0.002mm and X/Y-axis is 0.0125mm, an indicator of the span of the project. This points to parts of the model that go side to side as well as up and down.

The nozzle accepts 0.4mm or 1.75mm filaments, making it compatible with both standard sizes. The speed range of printing is between 20 to 100 mm per second, with travel speed attaining 100 mm per second. For best results, work at a speed of 60 mm per second.

FDM (Fused deposition modeling) print technology used for fusing together the filaments in the printing process.

Anycubic i3 Mega Review: The Bad

The manufacturer does not provide warranties. This is especially crucial if you don’t have a way to repair items when they break or order replacement parts when a part breaks. Contacting Anycubic for customer service can be also difficult. 

There are some not-so-pleasant things about the Anycubic i3 mega. 

Because this is a single extruder printer, you won’t be able to mix colors or filament types in your designs. This may have an impact on how the scaffolding for protruding sections of your prints develops. 

The varieties of printing filament used with this printer are limited to ABS, PLA, HIP, and wood composites.  The printer is not suitable if the work involves using other filament types or if the work area does not support exhaust any heat or substance fumes.

Objects with flat surfaces take longer to print due to the printer’s layer resolution.

Unpacking the Anycubic i3 Mega

The Anycubic i3 Mega S has neat packaging and comes in a large cardboard box. Polystyrene foam holds each component in place. One is pleasantly surprised by all the extras that come in the box as you open it:

The amount of filament given…a full 1KG spool of white PLA is mind-blowing. It is the most you can get for free from any printer.  A completely assembled spare hotend is also included, which is like a wonderful bonus.  The instructions in the manual along with helpful diagrams help in easily putting the printer together.

Unpacking the following items come in the box:

Mega base of the Anycubic i3

Anycubic i3 Mega’s base is of sheet metal and its vast footprint appears to be stable. The heated bed is on top of the base. Calibrate it before the first print because it’s already fastened to the printer’s Y-axis rail.

The power brick, most of the wiring, and the RAMboard (a.k.a. “the brain”) that controls the Anycubic i3 Mega’s movements are all hidden in the base.

Connectors, the power socket, the SD card slot, and a female USB plug may be all found on the base’s surface. The 3.5-inch capacitive TFT touch screen is also located on the front of the printer’s base.

There could be a slight cosmetic issue with the screen during our Anycubic i3 Mega unboxing. Small white particles of paper or other foreign garbage may be caught behind Anycubic’s hard sticker plate on the front of the machine. 

Mega frame of the Anycubic i3 Mega

This component is secured to the base using eight screws. Two rods, the X motors, the extruder, and the end stops make up the Z-frame. Everything is already installed in the frame, including the Bowden drive extruder. In a spiral cable wrap, all of the wires are neatly tucked away.

The User Manual

This contains all the Technical data, assembly instructions, and software installation guide. The user manual also has general recommendations and a troubleshooting guide.

PLA  Filament for the Anycubic i3 Mega

A 1-kilogram (2.20 pounds) spool of PLA filament is included with our Anycubic i3 Mega, packed in a plastic bag. The filament’s color may be of dark color.

Mega Spool Holder in the Anycubic i3 Mega

Four acrylic components and a removable rod make up the spool holder. It can accommodate standard 1-kilogram (2.20 pounds) spools as well as loose 3D printing filament.

The Mega Tool Kit 

This toolkit contains all of the necessary tools for assembling the 3D printer. It will also assist in tightening and loosening screws, as well as removing the 3D printer nozzle if necessary.

Wet Rubber Gloves

Locate the blue color gloves in the Anycubic i3  Mega package (they are easy to spot and wet).

The rods and mechanical parts have grease. Thus using the gloves can avoid getting smeared fingers and a greasy workbench during unboxing and assembly.

The Spatula for Scraping 

The Anycubic i3 Mega 3D printer’s heated bed is somewhat sticky. 

Use the print removal spatula included in the box when removing the prints. Be careful not to use too much force, since this could harm the bed coating.

Tweezers and Pliers

Use these to clean the heated nozzle of any residual filament. If you need to remove supports from your final prints, the pliers will come in handy.

Anycubic i3’s Removable Drives

Anycubic includes an 8GB SD card for storing files and comes with a SD card reader. This component is not required for the Anycubic i3 Mega 3D printer to function, but it is a wonderful bonus. There’s also a USB connector included in the box if you wish to connect the Anycubic i3 Mega to a PC, Mac, or Linux system.

Extra Hotend and Spares

Anycubic has included a spare hotend besides an extra end stop switch and spare screws.

Assembling the Anycubic i3 Mega

The Anycubic i3 Mega 3D Printer’s primary assemblies are pre-assembled. This makes the entire assembly simple enough (even for beginners) to complete in an hour or less.

i3 Mega Assembly Step 1: Checking Parts after Unpacking

Begin by extracting the components from the packaging and ensuring that all the components are present. 

The guidebook contains a helpful list that should assist you. Arrange the components in front of you. 

First, you’ll need the base and frame.

Anycubic i3 Mega Assembly Step 2: Assemble the Frame

The frame is attached to the base in the first stage. There are eight screws in total required. Four on the right and four on the left. Ensure that the frame is aligned correctly. If you look at the front of the 3D printer, you should be able to see the letters “Anycubic i3 Mega” on the frame.

Anycubic includes ten screws in the bag, so there is always some on hand. Tighten the screws without going overboard.

Anycubic i3 Mega Assembly Step 3: Plugging in and Wiring Up!

You may operate the Anycubic i3 Mega 3D printer with either 110 V or 220 V, depending on your region’s power grid. There is  a switch on the base’s left side to change this. Use an Allen key to change the voltage to the correct local voltage.

Next comes connecting the wires. This is also simple because everything is color-labeled. Red, green, and black cable connectors are available. The cables (green and black in color) are suspended from the frame.

Anycubic i3 Mega Assembly Step 4: Construct the Spool Holder

The spool holder is more than a decorative item; it also ensures the filament spool is not twisted.

The spool holder for the Anycubic i3 Mega comes in four pieces. Peel off the protective paper stickers first. The rest is simple: tighten the bolts into the side pieces by screwing them in. 

Use caution when applying too much power to these acrylic panes. They’re going to snap. When you set the rod on the spool holder, you’re finished.

Anycubic i3 Mega Assembly Step 5: Loading the Filament

The last step is to load the filament into the 3D printer. Check the filament by placing the spool on the spool holder ensuring it is not crooked and bent. Without a straight strand, the filament may get stuck in the Teflon tubing that leads to the hotend.

A filament sensor is included with the Anycubic i3 Mega 3D. When the filament runs out, the build will come to a halt. It’s now only a matter of threading the filament into the sensor. It can be found dangling on the printer’s right side. 

After that, press the metal ball on the magnetic plate beneath the feeding mechanism to secure the sensor to the frame. It should fit like a glove.

It’s now time to turn on the Anycubic i3 Mega 3D printer and preheat the nozzle for the first time. When it reaches the desired temperature, press TOOLS >PREHEAT on the touch screen to feed the filament into the motor from below. As soon as the filament emerges from the nozzle, you’re ready to go.

Anycubic i3 Mega Assembly Step 6: Make the Bed Level

The process of leveling the bed is rather simple. To allow the extruder to print on an even bed, adjust the bed of the Anycubic i3 Mega to a fully horizontal position.

Remove the paper sheet off the bed first, but don’t throw it away; it may be needed later.

Go to TOOLS > HOME > HOME ALL on the touch screen. All axes moved to the outermost and innermost places as a result of this. Next, disable the motors (HOME MENU > SETUP > MOTORS > DISABLE) in order for the axes to move freely.

Place the piece of paper on the printer platform and move the print head back and forth manually. Keep a look out for any nozzle contact with the print bed. Place the print head in the front left corner of the page. Release or fasten the screws until the nozzle snags on the paper. Continue with the diagonal corners until the bed is even.

Anycubic i3 Mega Assembly: The Final Word

It is as simple as 1-2-3 to assemble and set up the Anycubic i3 Mega. 

One may spend more time peeling labels from the spool holder than setting up the printer. The maximum time the i3 Mega 3D printer takes to set up is less than 30 minutes.

The documentation is in clear English and very handy for tackling any issues.

The Anycubic i3 Mega’s build quality is very impressive. The entire printer, except for the touch screen and its trapped dirt, leaves a solid impression.

There’s basically no way to use the cables in the wrong way (except for incorrectly using the 110/ 220 V switch).
