Minimum wall thickness can be quite thin when printing in strong materials such as high-detail stainless steel (0.3 mm) or titanium (0.4 mm).

Is a 2×6 wall stronger than 2×4?

In tall walls, where column buckling might be a factor, a 2×6 wall would be stronger if a structural sheathing was used. Structural sheathing provides lateral support to the 1 1/2-inch dimension of either 2x4s or 2x6s, but the greater width of the 2×6 makes it stiffer in that direction.
