Which is why Slic3r has modifier meshes (and S3D apparently offers something similar): you can apply specific slicing parameters to specific parts of the model.

If you were milling that mold / stamp out of aluminum, you'd use a fly cutter to flatten the surface and several end mills for the cutouts, then finish with a teeny engraving bit chucked in an air-powered spindle to crisp up the lettering, each moving with different speeds-and-feeds to get good results. (Well, you might; I can't justify that air spindle... [grin])

You wouldn't expect good results from an engraving bit run at the fly cutter's pace, right?

Same thing applies to 3D printing, except you choose the slicing parameters (speeds-and-feeds!) based on what you're trying to accomplish. Most 3D printed objects resemble Jabba-the-Hutt, where single set of generic parameters will produce decent results for the whole object. Your models definitely don't look that way, so you need different parameters for different parts.

On the other paw, most of my stuff looks like brackets made by Jabba-the-Hutt, soooo...

there is a combination to things to keep in mind .7 is a weird number as the machine work with .4 (one layer) .8 (two layer)
plus if u intend to work in .4 base geometry it's always better to use manual .39 as S3D sometimes skip some .4 partition if u manual give .4

viewtopic.php?f=3&t=2959&p=18833#p18833
i show the fact that S3D will skip some .4 wall here unless u set .39

another value that you want to modify in S3D to make .4 work best is

if you consider use 3 otuline/perimeter shell
.4 work well for 0.4 0.8 1.6 2.4 but is weird for 1.2 and 2.0
this with overlap 10%

Image

if you fix the overlap to 30-50%
you can wall all the wall nicely like this
for all 0.4 0.8 1.2 1.6 2.0 2.4 (.4x6 is the max of 3 outline)


for the tall and thin is a matter of speed/acceleration like most of the quality issue
