Abstract
Correction for ‘3D printed and stimulus responsive drug delivery systems based on synthetic polyelectrolyte hydrogels manufactured via digital light processing’ by Sonja Vaupel et al., J. Mater. Chem. B, 2023, DOI: https://doi.org/10.1039/d3tb00285c.
The authors regret an error in Fig. 6 due to a figure compilation error. The corrected Fig. 6 is shown below.

| Fig. 1 Mechanical properties of 3D printed hydrogels. Compression stress–strain curves of the (a) dried, (b) fresh and (c) swollen (in PBS) hydrogels with exemplary photos of HG 1 and HG 3, as well as tensile stress–strain curves of the (d) dried and (e) fresh hydrogels with exemplary photos of HG 1 (20 °C; n ≤ 3). HG 1 and HG 2 showed relatively high strains, coming with yielding at the dried state. Fracture behaviour for HG 1 and HG 2 was mostly ductile. The greater the amount of water included, the stronger the softening of the materials. These effects resulted due to the dominance of long-chained AETMA backbone in the polymeric network. HG 3 did not show yielding and relatively low strains. The fracture behaviour for HG 3 was brittle in the dried, fresh and swollen state, due to the dominance of short-chained PEGDA (Mn = 700 Da). | ||
