Okay trying something completely random, I am gonna start posting daily 1 minute printing tip videos on fixing common problems or improving overall quality of prints and be completely intense and over the top in the process.
But yeah seriously if you are getting rough looking PLA or TPU prints that look like this then the part is not getting cooled enough, quickly enough. The easy fix is to have 1-2 part cooling fans with a fan shroud that blows the air on the freshly extruded layer of the part.
Sometimes on large prints or printer with one sided part cooling fans I will setup a full sized fan to blow cold air on to a print to cool the hot areas faster.
You may also want to tweak other variables like your extrusion temps (but I like printing hotter than most recommened temps to ensure excellent layer adhesion for rock solid prints). If you liked this video or found it helpful feel free to comment your own tricks for fixing rough prints or suggesions on what I should cover next.
Tag a friend who also has shitty print quality to help them out.
