aeFlex™ TPU-78D

aeFlex™ TPU-78D is a high hardness TPU 3D printing material, higher surface hardness and modulus greatly reduce the TPU in the printing process because of too soft to jam the extruder, improve the success rate of printing.

Other sugggestions:

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™ TPU-78D 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™ TPU-78D.
