Poly(ε-caprolactone) and poly(ethylene glycol) based magnetic nanocomposite scaffolds were fabricated using fused deposition modeling and stereolithography approaches, and a hybrid scaffold was obtained by combining these additive manufacturing technologies. Viscoelastic properties in compression were investigated at 37°C, spanning a range frequency of four decades. Results suggest that poly(ε-caprolactone) and poly(ethylene glycol) based scaffolds adequately reproduce viscoelastic properties
