If you want smoother PLA prints without sanding, the biggest gains usually happen before the print finishes, not after it leaves the bed. PLA starts softening far below hotend temperatures, with a glass-transition range around… 

PLA heat creep is rarely a random failure. Most of the time, the print starts well, the nozzle looks normal, and then extrusion fades after the hotend has been working for a while. You hear… 

Printing abrasive filaments stops being simple the moment hard particles start scraping the inside of the nozzle. Carbon fiber, glass fiber, glow additives, metal powder, wood flour, and ceramic or mineral fillers do not all…
