    Strongest layer height?

    I initially assumed that the lowest layer height (0.1mm for instance) would make for the strongest parts. This, however, builds using small wispy strands that don't always adhere to each other perfectly. So I've been wondering if using 0.4mm or even larger layers might make for stronger pieces. Big fat cables of material globbed on there together might not be pretty, but may be better for strength.

    Thoughts?

    Smaller layerheights require better Z-calibration though. If i use 0.4mm layerheight with 0.5mm nozzle, it doesnt matter as much as with 0.25mm layerheight with a 4mm nozzle - which i used before swapping nozzle.

    But i believe using larger layerheights will increase tension strength in the horizontal direction. I dont know how increasing or decreasing the layerheight affects shearing strength...

    PLA.

    I generally use .1mm layers, but have done a .4mm for giggles (both on .04mm nozzle). Was just curious if there was a "general rule" that smaller layer heights were understood to be stronger or weaker. Might be worth experimenting.
