Potential of i3 Mega
It is the best 3D printer under 300 dollars available since 2019. The functions it offers are generally reserved for more expensive printers. The printer as a whole appears to be far more costly than the actual cost.
The slicer settings have a significant impact on the printer’s printing performance. Mega works with a variety of slicers, but focusing on Ultimaker Cura this time.
The default settings in the user handbook produce good results. With a few tweaks to the parameters, though, one can obtain even better results. Users will learn how to create the perfect Anycubic i3 Mega Cura profile in this article.
Take into consideration that different 3D printing applications demand different settings. For example, one wouldn’t print an action figure with the same settings as they would for printing prototypes with little features.
The Anycubic i3 Mega Cura profile is a more generic version for anyone who wants to improve on the preset.
Starting with basic tweaks and then to the settings. Finally, a summary of all the modifications to get the finest Anycubic i3 Mega Cura profile is provided.
Basic Printing Options: Printing Speed
Adjusting the print speed is one of the easier changes one can make to Anycubic i3 Mega Cura profile. Reducing the print speed from 60 mm/s to 45 mm/s may aid in obtaining better details on minor features.
Assume one is writing by hand. The more time users spend writing, the prettier it will appear. The same may be said of 3D printing.
Slowing down the speed reduces making mistakes. It is especially important when printing anything detailed or on a smaller size.
The model above was 3D printed at 45 mm/s on the Anycubic. The little chimneys on the roof, as well as the rest of the model, turned out well.
Basic Settings: Height of Layer
One of the most important factors for the Anycubic i3 Mega Cura profile, aside from print speed, is layer height.
Reducing the height of the layer will give the model more elegance. Adjusting the layer height from the typical 0.2 mm to 0.1 mm doubles the number of layers required.
Instead, split the difference and try printing with a 0.15 mm layer height if one wants a better visual look. This manner, the layer height is still reduced, but not to the point where the prints take twice as long to print.
Basic Settings: Infill Parameter
Infill is a useful parameter that impacts the model’s weight and rigidity. The standard recommended infill setting is 20 percent. Amazing thing about this infill % is that it doesn’t take long to print. It provides adequate stiffness to a part.
Consider increasing the infill to 40 percent or more if one needs to 3D print a working component.
This will provide the part more structural strength, which is crucial if it needs to carry weight. If users need a quick print, though, they can reduce the infill to 10 percent or less.
It’s crucial to think about the appropriate infill pattern for the print in addition to infill percentage.
Unless users require a particularly powerful portion, the basic grid design is usually a decent place to start.
Basic Settings: Temperature of Hot End and Bed
Next is how hot can the hotend get. There is no optimum Anycubic i3 Mega Cura setting for this parameter. As it is so dependent on the filament in question.
Classic PLA, for example, is often printed at 195° Celsius, which is the i3 Mega’s default setting.
Users should raise the hot end temperature if their PLA includes other materials as reinforcements.
For example, carbon fiber. But don’t worry: the hot end temperature is written on most filament spools.
The Anycubic i3 Mega Cura includes an “Ultrabase” heated glass bed with a texturing to reduce warping. Still, if the bed is exactly flat and users are experiencing warping, consider adjusting the temperature from 50 to 60 degrees Celsius.
This will increase the temperature of the lower layers, reducing the temperature gap between the new and “old” layers. As a result, there should be fewer tensions between the layers of the part, resulting in less overall warping.
Advanced Settings: Speed and Distance of Retraction
The hot end is coupled to a less obvious Anycubic i3 Mega Cura setting: the retraction speed and distance. The print head of the printer must move over the cross-sectional area of a part without printing in more complex 3D models. As doing so, the extruder motors draw the filament back a little so it doesn’t exit the nozzle while the print head travels.
One will observe filament strings between the part’s features if the retraction settings aren’t up to the task.
The speed at which the filament is drawn back through the nozzle is known as retraction speed. It’s set to 60 mm/s by default. The length of the filament that will be drawn back is defined by the retraction distance. It’s set at 5 mm by default.
Although the default settings aren’t horrible, it’s useful to know how to modify them. If filament stringing occurs, reduce the rate of retraction to 40 mm/s and the length of retraction to 4-4.5 mm.
Experiment with different retraction settings to fine-tune by oneself. It is recommended experimenting with the retraction speed in 5-mm/s increments. Also, 0.5 mm increments for the retraction distance is recommended.
Advanced Settings: Thickness of Initial Layer
Cura includes a variety of options that other slicers don’t have. This suggests there’s still room for improvement in the Cura profile.
The model’s size is something users might not notice in the photo above. It’s extremely large, standing 8.7 inches (22 cm) tall. Despite the model’s size, there is no problem with bed adhesion or warping. It’s because of the good bed calibration and the 0.15 mm beginning layer height. This option assures that the initial layer is thicker than the others. It improves bed adherence.
For Cura profile, it is strongly advised setting the starting layer thickness to at least 0.15 mm.
Advanced Settings: Thickness and Speed (outer and inner) of Shell
Shell thickness refers to the thickness of a part’s walls. Shell thickness, along with a few other factors (such as infill), determines a part’s strength.
The i3 Mega’s standard shell thickness is set at 1.2 mm. If one is 3D printing a product that requires a lot of rigidity, try increasing the shell thickness value.
But, once users have settled on the thickness, how about the speed of the inner and outer shells?
There are 3 walls next to each other to make the width, with the shell thickness of 1.2 mm and the nozzle diameter of 0.4 mm. The so-called outer layer is what users see after a part is finished. The inner layers are the other two. Cura lets one choose distinct print speeds for the inner and outside layers.
When printing the “thinking man” model shown above, the outer shell speed is kept at 30 mm/s.
It is important to print this nicely because it was the visible layer. This worked great, but if one is not happy with the results, feel free to make changes.
To save a few minutes on the print time, the print speed can be increased to 80 mm/s for the two remaining inner layers. Despite the fact that the quality was not compromised, the entire print time is reduced.
