Layer Adhesion and Anisotropic Strength in PETG
Printed PETG is weakest across layer lines because strength there depends on how well polymer chains inter-diffused before freezing — set by nozzle temperature, cooling, and layer time. Wall count, part orientation relative to load, and hot dry printing matter far more for strength than infill percentage.
