The largest shift was between 15% PEGDA + Alg, which increased in modulus from 57 ± 25 kPa without post-curing to 157 ± 49 kPa with post-curing. This decrease in mechanics from the bulk properties described above is attributable to the difference in gelation conditions between the two samples. The bulk properties tested with cast hydrogels were exposed to a large excess of light (5400 mJ/cm 2 ), which ensures that all photoinitiator is consumed and the network is fully formed. VAM printing was performed in ranges of 150-350 mJ/cm 2 . It should furthermore be noted that the bulk properties were done in static conditions, as compared to the dynamic nature of VAM, where partially polymerized chains can diffuse out of the printing region, leading to a much less efficient network being formed. Overall, the processing of these materials does affect the final mechanics of structures, which can be increased by secondary initiation, with further control possible through tailoring the initiator-to-reactive moiety ratio and curing conditions .
