Abstract Scope |
The growing demand for sustainable manufacturing practices has highlighted the critical need for developing new printable materials that align with environmental and scalability goals in additive manufacturing (AM). Thermoplastics are typically considered more sustainable than thermosets due to their recyclability but require high temperatures and associated high energy inputs to extrude, while many thermosets can be processed at ambient or moderate temperatures. This presentation will highlight recent efforts focusing on the development of sustainable poly(methyl methacrylate) precursors suitable for extrusion and in-situ polymerization at ambient conditions. Key formulation aspects—including rheology, reaction kinetics, processability, and thermo-mechanical properties—will be discussed. Compared to traditional extrusion-based AM of thermoplastic polymer composites, our approach offers a sustainable alternative by enabling low-energy processing, potentially enhanced interfacial bonding, and rapid feedstock deposition. Practical insights into tailoring feedstock composition to meet the demands of efficient, scalable AM via on-the-fly (OTF) active mixing will also be discussed. |
