Cura Infill Patterns: How to Choose the Right One for Your 3D Prints

One of the most important aspects of 3D printing is infill – the inner structure that supports the outer shell of your printed object. Without the proper infill, your prints can become weak, brittle, or may even fail to print. This is why choosing the right infill pattern is crucial to achieving top-quality results.

In this post, we’ll discuss the different infill patterns available in Cura, the popular 3D printing software, and provide tips on how to choose the right one for your prints.

Rectilinear Infill

The rectilinear infill pattern is one of the most commonly used infill patterns in 3D printing. It is a simple cross-hatch pattern that provides good support and stability to the printed object. It is easy to print and is the go-to infill pattern for many 3D printing enthusiasts. However, it can also result in a slightly weaker print due to the direction of the lines.

Triangular Infill

The triangular infill pattern is a popular choice for those who want added strength and stability in their prints. This infill pattern is particularly useful for printing objects that may need to withstand a lot of weight or stress. It is also a very efficient way to use filament as it requires less material than the rectilinear pattern. This infill pattern can be a bit tricky to print as it requires a printer that can handle bridging and overhangs.

Gyroid Infill Pattern

The gyroid infill pattern is a unique pattern that adds a touch of style to your prints. This infill pattern is made up of interlocking curved lines that provide good stability and strength to your prints. This pattern is particularly useful for printing complex shapes as it can conform to the object’s curves and angles. However, this infill pattern can be difficult and time-consuming to print, as it requires precise printer settings and support structures.

Cubic Infill

The cubic infill pattern is relatively new on the scene and is quickly becoming popular among 3D printing enthusiasts. It is a variation of the rectilinear infill pattern but with curved lines that create a more solid, yet lightweight structure. This pattern is particularly useful for printing objects that need to be light yet strong, such as drones or model aircraft. This infill pattern is easy to print and requires less material than most other infill patterns.


Choosing the right infill pattern can make a big difference in the quality and functionality of your 3D prints. While the rectilinear infill pattern is the most common, other patterns such as triangular, gyroid, and cubic can be highly useful in certain situations. Make sure to take into account the type of object you’re printing, the amount of support required, and the properties you want your print to have.

By experimenting with different infill patterns and adjusting your printer settings accordingly, you’ll be able to achieve top-quality results with your 3D prints.
