Choosing between PETG and ABS? Here is how they stack up on the properties that matter, plus a clear pick for each situation. PETG: PETG is strong and weather-resistant but strings easily, so tune retraction and keep the fan low. ABS: ABS warps badly without an enclosure and needs ventilation because of fumes.
Short answer: PETG wins on more categories overall (3 of 6), but the right choice depends on the part — see the recommendations below.
