Magnetic programming of 4D printed shape memory composite structures
Abstract
Abstract 4D printed shape memory polymers and their composites are currently a highly topical research area. The potential applications for 4D printed smart materials are wide-reaching, with particular promise for personalized medicine. In this work, we 4D printed various structures made of biocompatible and biodegradable polylactic acid (PLA) and PLA/Fe3O4 composite filaments. The shape memory behaviors of the 4D printed structures triggered by magnetic field were investigated. The printed structures can return to their original shapes with a high speed in just a few seconds. Moreover, the structures like bone tissues printed by PLA/Fe3O4 composites filaments with 15% Fe3O4 were actuated by magnetic field at 27.5 kHz. During the shape recovery process, surface temperature of the printed structures is uniform and around 40 °C. This physiologically relevant operating temperature range is a highly attractive feature for potential healthcare and biomedical applications.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
