Infill density to understand

Hi I am a student working with a Prusa for a project. I need help to understand better the infill density.

Basically I have to compare gyroid infill with honeycomb infill. I have 3D printed with Prusa and Prusaslicer several specimens, only infill, no walls. If for example I use 15% infill for honeycomb I have a mass of 4.8g, while with 15% for gyroid I have a mass of 3.4g. To get 4.8g for gyroid I need 20.6% infill density. I need the same mass to do comparisons.

Do you know what parameter the infill density in prusaslicer refers to? Do you know what is the relationship between infill density and the cell size for honeycomb and gyroid?

Thank you very much

I believe honeycomb puts an edging ring around the fill where as gyroid doesnt. This might be why the weights are different.

I would recommend to read 3d printing guide covered by Reviewsed.

Thank you for the link, I knew already the article but the meaning of the infill density is not explained. It is written: "Infill density is the fullness of the inside of a part." What does it mean? It is not related to the weight (or volume) otherwise 15% for honeycomb and gyroid should weight the same for my samples. Maybe each infill pattern has its own rule for infill density and they are not comparable?

Thank you for the link but the infill density is not mentioned

I have already using 3D printer snapmaker, tho I'm using it just for fun but I can see it is a future.
