When printing larger models at smaller sizes you can play with 'expansion' of details - I print on an FDM printer and have successfully printed 'in scale' models from 1:72 to 1:700 scale at scales of 1:333, 1:1000 and 1:2743 (9ft=1mm) by playing with the scaling factor, contracting by half the extrusion width overall (on the scaling tab) and then adding this lost size back as horizontal expansion to prevent thin walls being extinguished when scaling down.

Very large changes in scale are feasible if models are to be printed in one piece and moveable joints/parts are not required to mate correctly from distinct parts. I could do even more radical changes with a finer nozzle than the 'stock' 0.4mm one which was shipped with the printer. Results are 'FDM', with some visible layer lines, and not terribly good vertical 'rods', but a tilting of the model to make verticals or (nearly but not quite) horizontals at roughly 45 degrees to thicken top surfaces and increase the area of each section of a vertical rod does help with many types of print.

Previewing the print job and tweaking until it looks good on screen saves a lot of time, energy and filament (and presumably also resin, time and screen life for the resin printers).
