Shape memory behavior of printed constructs. (a) Schematic illustration of fabrication steps of constructs with shape memory capacity. (b) Digital photographs of different construct designs at dry state (temporary geometry) and in the hydrated state showing their shape recovery performance upon immersion in aqueous media. Constructs shown in (b) were composed of 4 layers and were 20 mm and 10 mm in length and width, respectively. Grids in the background had 5 mm × 5 mm dimensions. White arrow indicates crack formation in the construct during the re-hydration process.
