Researchers at the University of California Santa Barbara and Lawrence Livermore National Laboratory (LLNL) have developed a groundbreaking 3D printing system that can produce two distinct solid materials from a single print resin. This innovation marks a significant departure from traditional 3D printing methods, which are typically restricted to using one material at a time.
The novel technology utilizes a specialized resin composed of epoxy and acrylate monomers. The accompanying 3D printer emits both ultraviolet (UV) and visible light. By precisely directing these light beams, the system can selectively harden the resin into permanent structural components and, simultaneously, create dissolvable support structures. These temporary supports can be easily removed by immersing the printed object in a sodium hydroxide solution.
This advanced approach streamlines the 3D printing process, offering the potential to reduce complexity and minimize the risk of damage to delicate printed objects during post-processing. The ability to create dual materials from a single resin opens new avenues for sophisticated additive manufacturing applications.
