Ultraviolet (UV) light-assisted additive manufacturing (AM) needs biobased resins capable of rivalling traditional petroleum-based alternatives. This study introduces a resin derived from vegetable oil, filled with nanofibrillated cellulose (NFC), which boosts mechanical properties at extremely low NFC concentrations (0.1 – 1 wt%). Remarkably, adding just 0.1 wt% NFC resulted in a 2-fold increase in elongation at break and a 1.5-fold enhancement in impact resistance. Furthermore, incorporating 0.5 wt% NFC led to an almost 3-fold rise in tensile modulus and a 6-fold improvement in material toughness.
