ABS and ASA – Printing with Heated Chamber
For outdoor and heat-stressed parts. But needs enclosed chamber.
ABS and ASA are materials for demanding applications:
🔥 ABS (Acrylonitrile Butadiene Styrene): • Heat resistance: 90–100 °C • Excellent toughness • Good mechanical properties • Issue: shrinkage, emits odor • Ideal for: automotive parts, electronics enclosures
☀️ ASA (Acrylonitrile Styrene Acrylate): • Same properties as ABS • Excellent UV resistance (no yellowing, no cracking) • Better for outdoor use • Ideal for: outdoor covers, signage
🌡 Print settings: • Nozzle: 240–260 °C • Bed: 100–110 °C • Chamber: 40–50 °C (prevents warping) • Cooling: Minimal or none • Speed: 40–60 mm/s
🏗 Tips: • Without enclosure expect warping – build or buy one • Ventilate the room (styrene fumes) • Adhesive: ABS juice (ABS + acetone) for bed • Print on PEI or Kapton tape
