I have what are basically toy 3d printers capable of 1 micron precision…
Bullshit.
The thermal coefficient of expansion of say… Aluminum is 23.
That means that when a 1 meter piece of Aluminum rises from 20C to 21C, just one degree Celsius, it grows by 23 microns.
Your 3D printer is not a temperature controlled precision instrument. Your tolerances are no where close to 10 microns let alone 1 micron.
Bullshit.
You’re changing the premise of the question.
Pick a temperature - design your model to be whatever you need it to be at that target temperature - just like every other engineer with 26 years of experience, such as myself.
The problem isn’t that it can’t be done. The problem is that it is unnecessary and very expensive.
This is definitely true in terms of industrial production. (super cheap for “makers” - taking the hardware constraints into consideration with the design, of course).

Cool. Build 10 pieces and fit them together with sub 10 micron precision.
