*Warning
① The AMS lite supports spools with a width of 40-68 mm and an inner diameter of 53-58 mm.
② Avoid using AMS lite to print flexible materials, including TPU, TPE, or absorbent PVA.
Avoid using materials that are too hard (too high modulus) or too brittle (not enough
toughness), including third-party fiber reinforcement materials (PA-CF/GF, PET-CF/GF,
PLA-CF/GF, etc.). Please use external spool placement to print these filament.
