Vat photopolymerization (VPP)-based three-dimensional (3D) printing has been rapidly adopted by various industries, but challenges arise when attempting to print thermoplastic polymers via VPP due to mechanical and resolution limitations. Therefore, multifunctional oligomers or cross-linkers are commonly used, creating strong, rigid, and accurate prints, while printed thermosets impede recyclability due to difficulties in melting and reprocessing. To address this challenge, we propose here a sustainable conversion of the 3D-printed thermosets into processable thermoplastics by utilizing methacrylic anhydride (MAA) as a hydrolytic cleavable cross-linker. Our results show that the utilization of MAA can significantly enhance printing accuracy, mechanical performance, and thermostability of poly(isobornyl acrylate) on a VPP-based 3D printer. Importantly, the MAA cross-linker facilitates effective hydrolysis, transforming the printed thermosetting polymers into processable thermoplastics. Through systematic thermal, optical, and chemical analyses together with prototype fabrication demonstrations, we validate this sustainable conversion. Moreover, our results suggest that this sustainable conversion method shows no obvious compromise in mechanical performance, as observed in the prevailing dynamic bonding approaches. This highlights its potential as a more sustainable pathway for developing eco-friendly and mechanically robust materials for future 3D printing industry applications.

3D printing has rapidly evolved and matured in recent years, with a key factor being the improvement in printing materials. This paper compares the performance and applications of various 3D printing materials, including plastics, metals, ceramics, and biomaterials. Plastics remain the most widely used material due to their low cost and ease of printing, while metals are gaining popularity due to their superior mechanical properties. However, recent advancements in ceramic and biomaterials have opened up new possibilities for 3D printing in industries such as aerospace, healthcare, and electronics. The comparative analysis provides insights into the strengths and limitations of each material, and how they can be optimized for specific applications. With continuous developments in 3D printing technology and materials, the potential for this technology to revolutionize manufacturing and other industries is promising.

Rotational moulding is a unique low-shear process used to manufacture hollow parts. The process is an excellent process method for batch processing, minimal waste and stress-free parts. However, the process has drawbacks such as long cycle times, gas dependency and a limited palette of materials relative to other process methods. This review aimed to shed light on the current state-of-the-art research contributing towards sustainability in rotational moulding. The scope of this review broadly assessed all areas of the process such as material development, process adaptations and development, modelling, simulation and contributions towards applications carving a more sustainable society. The PRISMA literature review method was adopted, finding that the majority of publications focus on material development, specifically on the use of waste, fillers, fibres and composites as a way to improve sustainability. Significant focus on biocomposites and natural fibres highlighted the strong research interest, while recyclate studies appeared to be less explored to date. Other research paths are process modification, modelling and simulation, motivated to increase energy efficiency, reduction in scrap and attempts to reduce cycle time with models. An emerging research interest in rotational moulding is the contribution towards the hydrogen economy, particularly type IV hydrogen vessels.
