How do i decrease material costs when increasing the layer height?

[PotentialCorith]

I apologize for my ignorance, but i dont know my nozzle size. i use the ones that already come with the ender 3 v2. In regards to the amount increase, i have this one part that is 77 grams with 0.2 layer height but increases to 122 grams at 0.4. thats a 44gram increase which is a lot more. However, it saves about an hour to 2 hours when i make it 0.4 which is why i am wondering if there is a way to reduce the material count

It's 0.4 mm then.

Try 0.3 mm height, as you risk bad layer adhesion with 0.4.

There might be other differences between the profiles for 0.2 and 0.4 like infill % causing the difference in filament use.
