3D printing of tunable shape memory polymer blends

Herein we propose a facile strategy to prepare 3D-printable tunable shape memory polymers (SMPs) by melt-blending a commercial thermoplastic elastomer, SEBS, with polyethylene wax and low-density polyethylene. The SMPs are easy to process via traditional polymer processing apparatuses and suitable for a commercial fused deposition modeling 3D printer.
