Which resolution is needed for bricks compatible with Lego?
It's really more about calibration than resolution -- a poorly calibrated printer will have dimension errors that prevent mating with true LEGO bricks or other printed bricks.
Also, "resolution" is ...

Resolution Drawbacks
The biggest effect I've see on resolution is due to plastic stress due to thermal gradients.
The higher resolution prints build up more layers of material, and each layer has a cumulative effect on ...

How important is the minimum layer height on a 3d printer?
I believe the Slic3r Manual summarizes this quite nicely:
A thicker layer height will provide more flow, and consequently more heat, making the extrusion adhere to the bed more. It also gives the ...

Ultimaker Layer Resolution vs Nozzle Size
You need a certain minimum flow rate to achieve consistent extrusion. Flow rate is the product of print speed, extrusion width (proportional to nozzle size) and print speed. If you use a very small ...

How to obtain high resolution prints in a shorter period of time?
You could experiment with slicing. For example, you might not need high resolution all over the object, but you can speed up some straight parts by using greater layer high there. See a part of Slic3r ...

Smallest dot/dot indent for Prusa MK3S using PLA

Resolution Drawbacks
Regarding the sturdiness of the final print, I believe it depends on the inter-layer adhesion of the filament itself - which varies greatly. Also, normally, thicker layers would increase the strength ...

It's also worth noting that the ratio of nozzle diameter to layer height affects strength. The layer height is typically set slightly smaller than the nozzle diameter, so the nozzle "squeezes" the new ...
