3D Bioplotter Research Papers

In this work, we report the synthesis, characterization and three-dimensional (3D) printing of self-healing gels. The gels are prepared by cross-linking benzaldehyde-functionalized poly(2-hydroxyethyl methacrylate) (PHEMA) with ethylenediamine (EDA) to form dynamic imine bonds. An immediate gelation was observed within seconds, followed by a full maturation, enabling time independent and stable printing. The self-healing gels showed 98% recovery from mechanical damages. To establish a printable window for our well-defined system, and to allow robust printability, we examined a broad number of ink formulations. To tune the rheology towards the formation of soft and extrudable, yet stable and self-supporting materials, we examined…
