Standard PLA+ sticks well to most PLA-friendly surfaces. When it doesn't, the cause is almost always the plate, the first-layer height, or the temperature.
1. Wash the build plate
Fingerprint oils and residue are the most common cause. Wash the plate with hot water and dish soap, rinse it thoroughly, and dry it with a clean paper towel. Avoid touching the print area afterward.
2. Check the bed temperature
A heated bed isn't required, but it makes adhesion much more reliable. We use 60°C on smooth and textured PEI.
3. Check the first layer height
If the first layer looks round and barely touches the plate, the nozzle is too high. Adjust the Z-offset or rerun your printer's bed leveling, if it supports that.
4. Check the nozzle temperature
A generic PLA profile at 200–215°C is often too cold for Standard PLA+. Try 230–240°C. See Settings for printers without a profile.
5. Refresh a worn PEI sheet
Older PEI can lose its grip. Lightly scuff it with a green scrub pad and isopropyl alcohol, then wash it.
6. Add a brim for small or tall parts
Parts with a small footprint benefit from a brim, which adds contact area.
