Paragraph starter

The research by Gallicchio et al. (2023) highlights that the mechanical properties of composite materials, such as stiffness and strength, can be precisely controlled by adjusting the type and concentration of reinforcing fillers. This principle is crucial for developing materials suitable for additive manufacturing, as demonstrated by their successful 3D printing of a reinforced acrylic resin scaffold. This suggests that material formulation is a key design consideration for achieving specific performance requirements in 3D printed components.
