Text of Abstract
Growth printing (GP) is a morphogenesis-inspired 3D printing paradigm based on exothermic frontal ring-opening metathesis polymerization (FROMP) of dicyclopentadiene (DCPD). Once triggered locally, the reaction front self-propagates without external energy, curing liquid monomers into poly-DCPD. Unlike voxel-based methods such as FDM or SLA, GP grows continuously from an initiation nucleus, producing large, complex geometries. Here, we demonstrate that tailoring fluid properties expands the accessible design space: adding 15 wt% polybutadiene (PBD) to DCPD increases resin viscosity, enabling stable growth fronts and the formation of intricate 3D structures. Thus, viscosity-modified resins extend the versatility of growth-based manufacturing beyond neat DCPD.
