Showing texture/joins/seams when modelling for 3D printing - UV wrapping not relevant

Support Modeling

When modelling an object to be 3D printed any texture has to be explicitly modelled rather than represented with an image. For example, a model of a wooden floor. The small gaps or thickness variations between adjoining planks needs to be modelled.

Is there a method to select an edge, or series of edges, and score them to a certain width and depth?

Are there any tips, tricks, or best practices to use when constructing models with high levels of detail explicitly for printing?

You could use an image as a displacement map with a displace modifier. Apply the modifier for real geometry or if you export as .stl for printing there is an option to apply modifiers during exporting

That looks fascinating, thanks. I will have to have a play with modifiers.
