Print failures involving PETG detachment and layer separation are centered on adhesion and structural weakness across various printers. The failure modes manifest as perimeters detaching or visible structural weakness across multiple technologies.

Commenters are sharply split between attributing failures to environmental inputs versus mechanical print settings. 'kahjtheundedicated' and 'spitfire' hammer on wet filament and humidity as the primary culprits, demanding drying protocols. Conversely, 'NaibofTabr' argues failure stems from mechanical stress, viewing the object as a lever arm that tears preceding layers. 'ExcessShiv' blames the bonding failure between PETG and PLA supports. Meanwhile, 'digilec' insists on radically slowing down the first layer print speed for proper 'falling' adhesion.

The weight of the discussion points to multiple failures of the current process. The strongest consensus suggests adhesion issues linked to poor surface contact or internal stresses. The sharpest divide remains between whether the problem is the material itself (wet filament) or the machine parameters (Z-offset, speed). An outlier claim suggests the print's geometry—not the settings—might inherently limit achievable circular structures.
