| Abstract | Shape memory polymer blends were produced based on thermoplastic polyurethane (TPU) with poly(lactic acid) (PLA), including with the addition of single-walled carbon nanotubes or MXene nanoparticles as a reinforcing filler, and extruded to produce filaments for 3D printing by fused deposition modeling. A series of simple structures were printed and evaluated in terms of their shape memory effect, displaying large deformation and nearly complete shape recovery. The filaments printed similarly to commercial flexible filaments, although improvements in the filler integration and consistency of the filament diameter are needed to reduce print failures in larger prints with more flexible blends as well as to improve print quality. Addition of MXene or SWCNTs improved the stiffness and strength of the material. This improvement was associated with improved shape memory effect and increased recovery force, which are important for the use of SMPCs for actuation. The 3D/4D printed structures show large scale deformation capability, such as would be required for a deployable structure. |
