Please keep in mind thermal expansion of used material especially in XY plane. Printed parts are tempered by heatbed - then cooled down to room temperature so parts shrink.
Apply this linear relation: delta D´ = D * gamma * delta T
delta D´ = final dimension difference
D = original dimension
gamma = coefficient of thermal expansion for used material
delta T = printed part temperature difference between current temperature
while it's printed and ambient temperature in use
Example:
material PETG: HB temp. = 90 [°C]
amb. temp. = 25 [°C]
delta T 90 - 25 = 65 [°C]
gamma 0.000068 [m/m*°C] [1/°C] (doesn't matter if Celsius or Kelvin)
D 100 [mm]
Use basic unit!
delta D´ = D * gamma * delta T
delta D´ = 0.1 * 0.000068 * 65
delta D´ = 0.000442 [m] = 0.442 [mm]
Linear thermal expansion works for each layer if there's any delta T but every layer has different delta T if the heatbed temperates printed part - the higher layer position the smaller delta T. It's due to cooling printed part by ambient air and air flow from print fan.
