♻️ Can #polymer powders really be reused indefinitely in additive manufacturing? One of the biggest promises of powder-based AM is improved material efficiency. But what happens to powders that are exposed to elevated temperatures build after build? A new open-access study, co-authored by our #NETZSCH polymer experts Dr. Natalie Rudolph and Dr. Shona Marsh together with experts from the The University of Sheffield and Malvern Panalytical, investigates how glass fillers influence the aging behavior of nylon-12 (PA12) powders used in polymer additive manufacturing. Using NETZSCH thermal analysis and rheology solutions, the team revealed how thermal exposure changes powder properties over time: 🔬 #DSC was used to investigate melting and crystallization behavior and define processing windows. 📈 #Rheology provided insight into viscoelastic changes associated with powder aging and molecular weight growth. The findings contribute to a better understanding of powder recyclability, helping manufacturers: ✔ Optimize process parameters ✔ Reduce material waste ✔ Improve part consistency ✔ Extend powder usability for more sustainable AM workflows 📖 Read the full open-access paper to explore the experimental details and results. 💡And if you would like to dive deeper into material characterization for additive manufacturing, discover our free #ebook Thermal Analysis and Rheology in Polymer Additive Manufacturing. 👉 Click here: https://lnkd.in/dpH6yUJt #AdditiveManufacturing #3DPrinting #PolymerAM #PowderRecycling #PA12 #ThermalAnalysis #Rheology #Sustainability #MaterialsScience #ProvenExcellence
