Which infill should you use for 3D printing? 🤔
Grid, Crosshatch, Lightning, TPMS-D, Honeycomb, Concentric… which one is best?

The truth is: there’s NO universal “strongest infill.” Infill is always a balance between print speed, material savings, top-layer support, strength, and even flexibility (especially with TPU).

In this video, I explain how to choose the right pattern in Orca Slicer and Bambu Studio (and the same options in other modern slicers), covering:

🔹 Why Grid can cause issues on fast printers
🔹 Why Crosshatch became the new go-to
🔹 When to use Lightning to save material
🔹 TPMS-D for truly structural parts
🔹 Honeycomb and its strength
🔹 Concentric for TPU and flexible parts
🔹 Orca’s new structural settings (multiline, wall connection, real control)
