Assessment of printing performance. (a) Schematic representation of the proposed method to assess biomaterial ink’s qualitative printability. Initial screening of ink formulations to establish the ability to (i) produce grids with well-defined pores and (ii) fiber formation, as opposed to droplet formation. (b) Schematic representation of the proposed method to assess biomaterial ink’s quantitative printability. (i) Protocol for the assessment of printability and shape fidelity proposed by Schwab et al. [41]. (ii) Application of the protocol to our 3D virtual model. Scale bar 1 mm.
