Is this stringing worth trying to reduce?

I have a new MK3S+ that I built from a kit.  I'm quite pleased with it except for some stringing issues.  The pictured below show some of the stringing that I'm seeing.  I'm trying to decide whether it is worth the effort to reduce stringing or just apply a heat gun.  Thoughts?

Also, I saw in the comments on one of the posts about stringing that if you see filament keeps oozing out after it should top that this is a sign of wet filament.  Is that right?

 

Best Answer by Neophyl:

The first pic with the box sections, that's the really thin spiderweb stringing, I'd just hit that with a heat gun / blue flame lighter and they will shrivel right up.

The frog one looks more extensive and thicker.  However all your stringing looks like its down to damp filament.  If dry it first and check, before touching any settings in the slicer.

Thanks for the reply.  Now that I'm thinking about it, I didn't see any stringing at all with my first print, but now I am. 

I'm sure it depends on the environment, but about how long does it take PLA to start taking on water to the extent that you see stringing?  I keep the spool in the ziplock bag in came in with the desiccant and only have it on the spool when I'm printing, so it has been sitting out for a total of about 10-ish hours.  I opened the bag about two weeks before the treefrog print.  Is that long enough for a spool to start taking on water?

I got a sunlu dryer and dried the filament for six hours (same spool that I used for the print above).  Then I reprinted the same file with no changes to the settings.  There was considerably less stringing and it was easier to clean up.  There was another, more complicated file that had significantly more stringing before drying.  I reprinted that after drying and there was considerably less stringing.  The pictures don't really capture the difference very well, but cleaning it up was much easier afterwards and the density of the stringing was less.  

So I think the advice was correct and my issue was mostly due to damp filament.
