# Use Adaptive Layers and Infill Layer Thickness

## Recommended Posts

Posted (edited) · Use Adaptive Layers and Infill Layer Thickness
How would Cura handle it when Use Adaptive Layers is enabled and Infill Layer Thickness is set to a fixed value (not calculated by formula)?

For example, Line Height = 0.2 mm, Infill Layer Thickness=0.4mm, Adaptive Layers height = 0.1~0.3mm

My guess is:    Infill Layer Thickness is always rounded to be a multiple of the transient layer height. Is this correct?

Thank you!

Hi @fvrmr   Sorry for another question:

In most profiles, Infill Layer Thickness is calculated to be equal to Layer Height.

In my understanding, the calculation above happens ONLY at the start of printing. If Use Adaptive Layer is enabled, on each layer, Infill Layer Thicknes is still fixed at the initial value, and the transient infill layer thickness is from rounding the initial value of  Infill Layer Thickness, but not the transient layer height.

Is this correct? Thank you!

Hi @fvrmr   My test seems to suggest that that's wrong. In the mode of adaptive layers, Infill Layer Thickness seems to be is always a fixed times of the transient layer height, but NOT rounded to be a multiple of the transient layer height. Are you sure?

For example,

Layer Height (set, fixed) = 0.2mm

Infill Layer Thickness (set, fixed) = 0.5mm

ROUND(0.5/0.2, 0)=3

When the transient layer height is 0.3mm,

the transient Infill Layer Thickness = 0.3mm×3 = 0.9

In other words, the TIMES (3), or the number of combined infill layers, would be kept constant for all the layers! This causes certain serious problem for the layers for biggest layer height.
