Real World aside: The other day I tried to 3D print small text. (Not super small, just the usual 0.4 nozzle size.) Comic Sans worked out best for this due to pretty constant line width.
Fonts with 'routed' in their names are often a good place to look for this - they're named thus because they were designed to be scribed/engraved with a router, so very frequently have a constant width.
I was once given a 3d print of my name by one of my father's friends who had a 3d printer at home.
I think this was what font they used except they had it all connected , that is if I am typing "test" then t is connected to e and then s and then t , in probably the same font as that of Comfortaa.
