If you want to achieve high-speed printing, it is recommended to use direct extruders, such as BMG extruder, Titan extruder and Hemera extruder, and appropriately increase the nozzle temperature.
TPU material is very easy to absorb moisture when exposed to air, and printing after absorbing moisture will result ozzing, extruding with bubbles and rough surface appearance, thus reducing print quality. It is recommended that put the filament into a dry box (humidity below 15%) immediately after opening the aeFlex™ TPU85A-HF vacuum foil bag for printing. Please put the unused filament back into the original aluminum foil bag for sealed storage.
After the material is damp, there will be more printing ozzing, bubbles extruded and rough printing surface. Please dry the filament in an oven at 70-80°C for 4-6h to restore the printing quality of aeFlex™ TPU85A-HF.
