Material Density Usage

In Cura 6.0 Material Properties, what is the "Density" parameter used for?

There is no Cura 6.0. I think you are talking about Cura 3.6.0.

 

The density is used to calculate the weight of the material that is used for a print. The slicers knows the lenght of the material that is extruded. To know the weight, you also need the diameter of the material, and the density.

OK, but does the density value have any affect on the extrusion process?  Does it change the amount of material extruded like the feed rate percentage on my Ender 3 does?  I seem to get better prints with some of the material profiles if I adjust the feed rate a little, while other profiles work well as is.

The density is only used to show the weight of the extruded material. It does not affect slicing.

Thank you. I will look elsewhere for causes.

Note that Cura has a “flow” setting (in the Material category of the sidebar) which will let you affect the amount of material extruded

Thanks again.  I just discovered that there were more setting available by choosing "advanced" or "expert" mode.  The flow setting is only there in the "expert" mode.
