Abstract Scope |
Personalization in medicine has been touted since the advent of 3D printing. A constant limitation has been the commercially available biomaterials compatible with 3D printing methods, which has limited the impact of clinical 3D printing and can be seen by the stagnated uses that primarily include models and prosthetics as opposed to implantable devices. Among the challenges that must be addressed are polymer composition as well as scaffold morphology and lifespan of the device in vivo. Polymer foams and printed porous scaffolds are promising classes of biomaterial, as the porosity and tunable physical properties are often better matches for native tissue compared with solid polymer analogs. Polymer thermosets produced by “click” reactions, including thiol-ene and thiol-epoxy crosslinking, are capable of being into scaffolds and foams where physical properties and morphologies may be tailored through a combination of chemical composition and physical processing methods. Compositional selection may further be used to introduce feedback mechanisms into the scaffold design. |
