Anycubic I3 Mega

The printer with the best print bed ever

The Anycubic I3 Mega is a printer that is being sold for around $300,00 at different Chinese websites, like Gearbest, Banggood, etc. 

The printer is equipped with the Anycubic Ultrabase bed. This is a glass bed with small particles of some strange material on top of it. The bed is ideal for holding PLA and ABS and also PETG prints pretty good on it, although you need a little trick to print with PETG on this printer (more on that a bit lower in this article).

The bed size of the Anycubic I3 Mega is 210x210 millimeter and the height of the print is maximum 205 millimeter. The printer has a dual Z axis steppemotor and leadscrew combination so that the carriage is always at the correct height. Also, both the sides have a sensor for height measurement so that the X axis is always leveled before the print starts. No way you can go wrong here.

Now another strong feature of this printer is the fact that the printer is made out of only one construction. You don't have a separate box standing at the side of the printer. This takes less space on your desk and if you have multiple printers next to each other, like in a printer farm, you don't have cables going around everywhere.

The filament if placed in a separate filament holder, made out of acrylic. I don't like this holder but hey, this is a 3D printer. Just print a new holder that can hang on the right side of the printer. Piece of cake to do this.
When the printer runs out of filament, the special filament sensor detects this and pauses the print. You can then re-insert some filament and continue printing.

Power Loss Management

Yes, this printer is equipped with Power Loss Management. These are nice words for something like, 'When there is a power loss, the printer can continue where it stopped printing'.

Well... No !!!
This printer has the feature build in but it's useless. With the Ultrabase bed the printed material sticks to the bed like a charm but after a power loss situation, the bed cools down and the Ultrabase looses it's power to grap to the print. Your print will be loose on the bed and when the printer would restart it would just push the print away from where it was. No need to try this out, it just doesn't work.

As said earlier, the Ultrabase bed is very good for use with PLA and ABS but I like to print with PETG because it's such a nice material to print with. It's stronger then PLA and way easier to print with then ABS. The only downside of printing with PETG is that it stick just a little less good on the Ultrabase bed.

When printing on the Ultrabase bed I use a large brim around my object. Sometimes I use 30 to 40 lines of brim just to make sure the corners won't lift from the bed. Also, I sometimes tape the material to the bed, as you can see in the video above.
