Choosing between TPU and PETG? Here is how they stack up on the properties that matter, plus a clear pick for each situation. TPU: TPU is flexible and prints best slow with a direct-drive extruder; Bowden setups must go very slow. PETG: PETG is strong and weather-resistant but strings easily, so tune retraction and keep the fan low.
Short answer: PETG wins on more categories overall (4 of 6), but the right choice depends on the part — see the recommendations below.
