WebHeat makes the resin’s polymer network available for cross-linking. Light photons then cause cross-linking to happen between the polymers. As the polymers cross-link, the material becomes harder and stronger. This way, curing maximizes the material properties of Resin 3D parts as heat and light work together in controlled synergy. WebA structure-supporting polymer is then needed, that can withstand the harsh conditions of the curing process, protecting the pore structure obtained by freeze-drying. [ 147 ] In short, the freeze-drying of PGS includes pouring a PGS solution into a Teflon mold, which is then frozen at -20 °C and placed in a freeze dryer for lyophilization.
