The Polymer Processing Society (PPS), the world's largest society dedicated to the advancement of polymer science and engineering, recently celebrated its 40th Anniversary with a significant conference held at The University of Auckland | Waipapa Taumata Rau, from 22 to 25 April 2025. This prestigious international event convened leading researchers, academics, and industry experts globally to discuss the latest breakthroughs in polymer processing. Malta showcased a strong and impactful presence with a notable number of delegations presenting their cutting-edge work.
The Maltese contingent, led by Prof. Arif Rochman, delivered compelling presentations across key areas of polymer processing and additive manufacturing. Ms Rebecca Clark presented research from the CONFORM project on the "Development and Analysis of Novel Freeform Conformal Cooling Channels in Additively Manufactured Injection Moulding Tools", highlighting a novel cooling channel shape for efficient and effective cooling. Sarah Mifsud presented the findings from the VacuUM project on "Innovative Air Trap Mitigation in Injection Moulding: Efficiency and Effectiveness Assessment", showcasing the positive effects of the active vacuum venting system developed for a more sustainable moulding process. As part of the REO3D project, Ing. Albert Curmi discussed "Online Rheological Measurement in Screw Extrusion Additive Manufacturing for Improved Process Modelling", emphasizing advancements in real-time process control in additive manufacturing. Prof. Arif Rochman presented his work on "High-Speed MEX Additive Manufacturing of High-Performance Polymers – Process and Parts’ Quality Analysis", exploring the potential of rapid processing of advanced materials.
Beyond the impactful presentations, the PPS 40th Anniversary Conference provided a vital platform for the Maltese delegation to engage in extensive networking with global experts. These interactions facilitated the exchange of knowledge and the exploration of potential collaborations in areas such as additive manufacturing, simulation and modelling, and advanced polymer materials. The significant contributions from Maltese researchers at this prestigious international event demonstrate the nation's growing innovation in polymer science and engineering – a critical driver for sustainable and smart advancements within Malta's plastic manufacturing sector, aligning with its Vision 2050.
