Bed adhesion is the grip between a print's first layer and the build plate. Poor adhesion causes warping, curling and failed prints; excessive adhesion damages the plate or the part.

The recipe for good adhesion

  • Clean surface: grease-free (soap + water for PEI; IPA for glass)
  • Correct bed temperature: PLA 45–60 °C · PETG 70–85 °C · ABS/ASA 90–110 °C + enclosure · PA 60–80 °C with glue
  • Right surface: PEI for most, textured PEI for PETG/PA, garolite for nylon
  • First-layer tuning: height, speed (20–30 mm/s) and brims for tall parts

Why it fails

Finger grease, wrong Z-offset, drafts, bed temp too low, or an incompatible surface-material pair (PETG on bare smooth PEI = over-adhesion; ABS on cold glass = no adhesion). Every VOXFIL material page lists its bed temperature and surface.
