For volumetric printing, a Tomolite printer from Readily3D and the updated Apparite software were used. To optimize printing parameters towards clearly defined constructs, a laser dose test was conducted for each resin. Defined spots were created on the wall of a quartz cuvette filled with a resin by the laser beam (λ = 405 nm) for varying exposure times ranging from 4 to 16 s and varying average light intensities ranging from 4 to 16 mW cm -². The light dose threshold (mJ cm -²) required for precise photopolymerization and minimal off-target exposure, was calculated by multiplying exposure time with the average light intensity of the weakly visible polymerized spots in the cuvette. Construct printing was performed in a glass vial with 10 mm diameter in 1 mL of resin. The printed objects were washed by PBS pre-warmed to 37 °C.
