The Challenge Dymax is creating solutions that allow photopolymer-based 3D printing resins to meet or exceed the capabilities of thermoplastic materials such as polycarbonate or ABS, targeting superior impact and temperature resistance properties.
.
The goal is improvements in impact strength while maintaining a high Heat Deflection Temperature (HDT). Stronger UV-curable materials with high HDTs are generally low in impact resistance, being more inflexible or brittle due to a high degree of cross-linking in their molecular composition. On the other hand, high molecular weight materials with low crosslink density typically have a low HDT or are too high in viscosity to properly 3D print.
.
To solve this persistent problem and achieve advancement in balancing these properties, chemists need to determine the best formulation approach to attain this balance of properties within a UV-cured polymer network. To identify the best options for 3D printing oligomer development , Dymax explored one concept […]
