some math i found helpful. please note this is all at optimal...

lattice : number to place x 80 = unfocused / uncut all
mael : number to place x 80 = metal bars / stone slabs needed // x 40 essence orbs
flow : number to place x 80 = stone bricks / essence needed // x 40 metal bars
-
imbar : number to place x 30 = metal bars / essence orbs
primesce : number to place x 30 = essence orbs / focused
excor : number to place x 30 = stone bricks / metal bars

-----

for example, a corridor:

lattice : 14 => 1120 uncut each of malach/tourq/garn -> 560 tri-cuts / 1120 unfocused -> focused
mael : 7 => 1120 metal ore -> 560 bars / 560 stone slabs // 560 essence -> orbs
flow : 7 => 1120 stone slabs -> 560 bricks / 560 essence // 560 metal ore -> bars
-
imbar : 14 => 840 metal ore -> 420 bars / 840 essence -> 420 orbs
primesce : 7 => 420 essence -> 210 orbs / 420 unfocused -> 210 focused
excor : 7 => 420 stone slabs -> 210 bricks / 420 metal ore -> 210 bars
