Is there a function to dilate/erode a mesh in meshlab?

Question

I'm using a 3d printer that create to wide walls (all dimensions are 0.3mm too big) also I need to correct the stl file by eroding it. Is there such a feature in meshlab ?

Answer 1

A different method (slower but topologically more accurate) is using the uniform mesh resampling filter and specifying a positive (negative) offset for obtain a dilate (erode) effect. In this case a new, approximated, mesh is created and precision (and time) depends on the precision parameter you set.
