Printability map of both hydrogel-based and polymer-based inks predicted by ML algorithms. (A to C) The printability map of F127/LP hydrogel nanocomposites predicted by DT, RF, and DL, respectively. (D to F) The printability map of PCL/nHA in DCM polymer nanocomposite inks predicted with DT, RF, and DL, respectively. The green triangles and red crosses mark the printable and unprintable formulations, respectively, in the training data. The green and red areas are the predicted printable and unprintable regions, respectively, mapped from the testing results.
