Given that the PEG macromonomers are semicrystalline with a melting point (Tm) in the range of 40-60 °C (Figure ), their 3D printed networks may offer shape-memory properties. To test this, we printed an ETH logo and a stent prototype from PEGDMA 6k with 2.0 wt% BAPO-PEG. As the 3D printed products have high flexibility above the Tm of PEG, they were easily deformed at ~80 °C and fixed in the temporary shape by cooling to -20 °C. When heated again above the Tm of PEG, the deformed ETH logo and stent prototype fully recovered to their original shapes in a few seconds (Figures and). Therefore, these PEG macromonomers hold a promise for the design of personalized shape-memory medical devices thanks to their excellent printability by heat-assisted DLP.
