The Concentric infill pattern is a type of infill pattern used in 3D printing. It involves creating concentric squares, circles or rings within the interior of a printed object to provide structural support. It’s like when you drop a pebble in a pond and the ripples spread out in circles.
What Is Concentric Infill?
A concentric infill is a specific type of infill pattern where the infill lines are printed in a circular pattern that radiates out from the centre of the object. This pattern can be useful for objects that need medium strength in all directions, as the circular pattern can provide support.

Concentric Infill Settings In Cura Slicer:
1. Start by launching the Cura software on your computer.
2. Click on the “Open File” button (usually located at the top left corner) and select the 3D model file you want to print.
3. Click on the model that appears on the virtual build plate.
4. Open Print Setup: On the right side of the screen, you’ll see a panel titled “Print Setup”. Here, you can adjust all the settings for your print.
5. Scroll down until you find the “Infill” section. Click on it to expand the options.
6. In the “Infill Pattern” dropdown menu, select “Concentric”. This will set the infill of your print to be concentric circles.
7. Below the “Infill Pattern”, there’s an option for “Infill Density”. This determines how much of the inside of your print is filled with material. A higher percentage means a denser, stronger, but also heavier and slower-to-print object.
8. Once you’re happy with your settings, you can save them by clicking on the “Save to File” button at the bottom right of the screen.
9. Now, you can start your 3D print with your new concentric infill settings.
Advantages of Concentric Infill Pattern:
Lets now look at some advantages of using concentric infill in 3D printing:
1. Strength: While not as strong as some other infill patterns, concentric infill still provides a good amount of strength and stability to the printed object. It’s especially good for cylindrical objects or objects with curved surfaces.
2. Material Usage: Concentric infill can use less material than other infill patterns, making it a more economical choice in some cases.
3. Aesthetic Appeal: Concentric infill patterns are often more visually appealing than other infill patterns. They create a smooth, consistent pattern that can be seen if the outer shell of the print is semi-transparent.
4. Flexibility: Concentric infill can provide more flexibility to a printed object, which can be beneficial for certain types of prints.
Disadvantage of Using Concentric Infill Pattern:
Lets now look at some Disadvantages of using concentric infill in 3D printing:
1. Less Strength For Outer Wall: We’re referring to the fact that the outermost layer of a 3D printed object might not be as strong or durable since inner layer are not connected well enough with the outer shell or wall.
2. Inconsistent Infill: Concentric infill can sometimes lead to inconsistent infill, especially in models with complex geometries. This can affect the overall quality of the print.
3. Poor Layer Adhesion: Concentric infill patterns can sometimes lead to poor layer adhesion, especially on the top layers of the print. This is because the circular pattern doesn’t provide as much surface area for the next layer to adhere to, which can lead to gaps or weak spots in the print.
4. Inefficient Material Use: Concentric infill patterns can also be less efficient in terms of material use. Because the pattern is circular, it can leave more empty space within the print compared to other patterns. This means you might end up using more material to achieve the same level of strength.
5. Less Stable: Concentric infill patterns can be less stable than other patterns. This is because the pattern doesn’t provide as much support to the outer walls of the print, which can lead to warping or distortion, especially in taller prints.
