How to Fix First-Layer Adhesion Problems
23 Sept 2026 · 1 min read
If the first layer doesn't stick, nothing else matters. These are the fixes we check, in order, when a print lifts or turns into spaghetti.
1. Level the bed (or re-run auto-leveling)
Even printers with auto-leveling drift after moving or nozzle changes. Re-run the mesh before long prints.
2. Set the right Z-offset
The first layer should be slightly squished — lines touching each other with no gaps, but not so low that the nozzle scrapes. Adjust in 0.02 mm steps while printing a test square.
3. Clean the build plate
Fingerprints are the #1 cause of poor adhesion. Wipe the plate with isopropyl alcohol and avoid touching the print area.
4. Check temperatures
- PLA: bed around 55–60 °C
- PETG: bed around 70–80 °C
5. Slow down the first layer
Printing the first layer at 20–30 mm/s gives the plastic time to bond.
6. Use a brim for small parts
Small footprints like keychains or thin letters benefit from a 3–5 mm brim that you trim afterwards.
