Start with the first layer
Many print quality issues start at the bed. Check bed leveling, nozzle height, bed temperature, surface cleanliness, and adhesion before chasing advanced settings.

How to Improve 3D Print Quality
Improve 3D print quality by diagnosing first layer issues, temperature problems, stringing, supports, layer lines, speed, and filament condition.

Match settings to the material
PLA, PETG, ABS, TPU, and specialty filaments need different temperatures, cooling, and speeds. Use manufacturer guidance as a starting point, then test on your printer.
Change one variable at a time
If you change speed, temperature, retraction, cooling, and supports all at once, it is hard to know what fixed the issue.
Track successful settings
PrintNext projects and printer context help you keep successful settings tied to the material and model where they worked.
FAQ
Common questions
What should I fix first for better print quality?
Start with the first layer, filament condition, and correct material temperature before advanced slicer tuning.
Why are my prints stringy?
Stringing can come from wet filament, high nozzle temperature, insufficient retraction, travel settings, or material behavior.
Why do my prints have rough surfaces?
Rough surfaces can come from temperature, speed, cooling, moisture, support interfaces, or model orientation.
How does PrintNext help quality over time?
PrintNext helps keep printer, filament, and project history together so successful settings are easier to repeat.
