Tri Hexagon Infill Pattern In 3D Printing

Tri-Hexagon infill is a pattern used in 3D printing to fill the inside of an object with triangles and hexagons-like structures. It helps to provide support and strength to the printed object. The pattern consists of interconnected hexagons arranged in a triangular shape. This infill pattern is commonly used because it offers a good balance between strength and material usage.


What Is Tri-hexagon  Infill?

Tri-hexagon infill is a type of infill pattern used in 3D printing. This infill is a specific pattern that consists of interconnected triangles and hexagons. In this pattern, you can notice hexagons are usually larger in size when compared to triangles.

This pattern is often chosen because it offers a good balance between strength and material usage. It helps to provide structural integrity to the printed object while minimizing the amount of material required.

Tri-Hexagon Infill Settings In Cura:

Follow the below simple steps to setup tri hexagon infill settings in Cura:

1. Open Cura and load your 3D model.

Open STL File Cura Slicer

2. Go to the “Infill” tab on the right-hand side of the screen.

3. Under the “Infill Pattern” dropdown menu, select “Tri-Hexagon”.

5. You can also adjust the infill line distance, infill overlap, and infill layer thickness if desired.

6. Once you’re satisfied with the settings, click the “Slice” button to generate the G-code for your 3D printer.

7. Save the G-code file to your desired location, transfer the G-code file to your 3D printer and start the printing process. Your 3D printed object will now print using Tri-Hexagon infill.

Advantages Of Tri-Hexagon Infill Pattern: 

Let’s look at the advantages of Tri-hexagon infill pattern:

  1. Efficient material usage:  The Tri-hexagon pattern optimizes material usage by minimizing the amount of filament required for infill.
  2. Increased strength: The Tri-hexagon pattern provides excellent structural integrity to the printed object. The interlocking hexagons create a strong and stable infill structure, making the printed part more robust.
  3. Faster print times: The Tri-hexagon infill pattern allows for faster print speeds compared to other complex infill patterns like Gyroid, Honeycomb etc. The interlocking hexagons provide good support and stability, allowing the printer to move quickly without compromising the quality of the print.
  4. Improved print quality: The Tri-hexagon infill pattern helps to reduce visible layer lines on the printed object’s surface. The interlocking hexagons distribute the infill material evenly, resulting in a smoother and more aesthetically pleasing finish.
  5. Material savings: The Tri-hexagon infill pattern requires less material compared to other infill patterns while still maintaining structural integrity. This can result in cost savings and reduced material waste.
