Lab explores new resins for light-based 3-D printing
LLNL researchers used molecular dynamics (MD) simulations to study the polymerization of three different molecules from the same reactive group (acrylate) but containing different nonreactive components.

A Lawrence Livermore National Laboratory (LLNL) team has simulated the cross-linking of 3-D-printed polymer networks, a key step toward developing new functional resins for light-based 3-D-printing techniques including two-photon lithography (TPL) and volumetric additive manufacturing (VAM).


The team used molecular dynamics simulations to study, at a microscopic level, the kinetics and topology of three different molecules from the same reactive group (acrylate) but containing different nonreactive components. The researchers found that differences in the dynamics and structure of the resulting cross-linked polymers, built using the TPL and
