ABS

Pros:

  • High heat resistance: ABS can withstand higher temperatures (up to ~100°C) without deforming, making it suitable for parts near motors or electronics that generate heat.

  • Good impact strength: ABS is tougher than PLA and PETG, making it more suitable for structural components that need to endure crashes or mechanical stress.

  • Post-processing friendly: ABS can be sanded, drilled, and smoothed with acetone vapor, allowing for cleaner finishes and stronger joints.

Cons:

  • Difficult to print: ABS requires a heated bed and an enclosed printing environment to prevent warping and cracking. It’s more sensitive to temperature fluctuations during printing.

  • Fumes during printing: ABS emits unpleasant and potentially harmful fumes, so good ventilation is essential.

  • Moderate flexibility: ABS is more rigid than TPU but less brittle than PLA. It can flex slightly under stress but may crack if pushed too far.
