Quick Picks
Do not start by buying random adhesives. First clean the bed, confirm Z offset, confirm the bed temperature, and check that the material matches your build surface. Then use adhesion helpers only when they solve the actual problem.

Bed adhesion problems are usually caused by one of five things: dirty bed, incorrect Z offset, wrong bed temperature, wrong surface for the material, or poor first-layer slicer settings. Adhesion tools help, but they should not cover up a badly tuned first layer.
1. Glue Stick
Glue stick can help with prints that lift, materials that need a release layer, or surfaces that are inconsistent. Use a thin, even layer. Too much glue can create texture, mess, and inaccurate first layers.
2. PEI Build Plate
A good PEI build plate can improve adhesion and print removal, especially if the original surface is worn or inconsistent. Printer-specific fit matters: confirm exact bed size and magnetic compatibility before ordering.
3. Bed Cleaning and Maintenance
Finger oils, dust, plastic residue, glue buildup, and old filament can ruin adhesion. Clean the build surface according to the surface manufacturer's guidance. Avoid harsh methods that damage coatings.
4. PLA vs PETG Adhesion
PLA is usually easier for first-layer tuning. PETG can stick too strongly to some surfaces or string if wet/tuned poorly. Use the right surface, the right temperature, and the right release strategy.

| Problem | Check first | Tool/helper |
|---|---|---|
| First layer not sticking | Z offset, dirty bed, bed temp | Glue stick, PEI plate |
| Corners lifting | Drafts, bed temp, cooling, material shrinkage | Brim, glue stick, enclosure control |
| PETG sticking too hard | Surface compatibility, release layer | Thin glue layer as release helper |
| Prints remove poorly | Cool-down behavior, build surface condition | Flexible PEI plate |
| Rough first layer | Nozzle height, flow, bed leveling | Calipers, calibration print |
5. Calibration and First-Layer Checks
Digital calipers help you check calibration prints and part accuracy after first-layer issues are solved. If every print is dimensionally off, tune flow, slicer profile, and printer mechanics instead of adding more adhesive.
6. Moisture Can Look Like Adhesion Trouble
Wet filament can cause popping, rough extrusion, inconsistent lines, and weak layers. If the first layer looks bubbly or uneven, filament moisture may be part of the problem.
Final Recommendation
For bed adhesion, start with cleaning and Z offset. Add glue stick for specific materials or stubborn lifting. Upgrade the build plate if the current surface is worn, damaged, or inconsistent. Avoid stacking fixes until you know which problem you are actually solving.
