%X In the current work, we prepared a novel material suitable for additive manufacturing by using acrylonitrilebutadiene-
styrene (ABS) copolymer as matrix and a thermoplastic polyurethane (TPU) as additive. Conditions
for successful printing via fused filament fabrication (FFF)were optimized for the ABS:TPU blends. Compatibility
of ABS and TPU in the blends was studied by Fourier-transformed infrared (FTIR) spectroscopy, showing the appearance
of new supramolecular interactions via hydrogen bonding. Compositional studies were carried out by
confocal Ramanmicroscopy and atomic forcemicroscopy (AFM), demonstrating the good compatibility between
the two compounds. Mechanical and adhesive properties were studied by 3D-printing different normalized test
specimens in different directions. Itwas shown that blends containing 10–20wt% TPU led to enhanced adhesion
between layerswithout loss in yield strength,while 30wt% TPU led to a good adhesion between layers and to the
printing platform when printing at room temperature.
