Conditionsfor successful printing via fused filament fabrication (FFF)were optimized for the ABS:TPU blends. Compatibilityof ABS and TPU in the blends was studied by Fourier-transformed infrared (FTIR) spectroscopy, showing the appearanceof new supramolecular interactions via hydrogen bonding. Compositional studies were carried out byconfocal Ramanmicroscopy and atomic forcemicroscopy (AFM), demonstrating the good compatibility betweenthe two compounds. Mechanical and adhesive properties were studied by 3D-printing different normalized testspecimens in different directions. Itwas shown that blends containing 10–20wt% TPU led to enhanced adhesionbetween layerswithout loss in yield strength,while 30wt% TPU led to a good adhesion between layers and to theprinting platform when printing at room temperature.
