2kg - 3DE Premium - PBT+ - Pirate Black - 2.85mm Ultimaker news Optimized airflow2kg 3DE Premium PBT+ Pirate Black 2. 85mm PBT+ (polybutylene terephthalate) provides many of the same properties as nylon, but absorbs less moisture (humidity), allowing PBT+ to maintain its shape in wet environments. PBT+ is often used as a substitute for Nylon 6. 6 or 6. 12 and has better abrasion resistance than polypropylene or polystyrene. PBT has good mechanical properties in relation to stretching, twisting and bending (good "bend recovery").
