Special Issue Information

Dear Colleagues,

From the perspectives of engineers, physicists, researchers, and scientists, we intend to analyze and discuss different modern perspectives on materials processing. The high potential of enhancing a material through processing (thermal or mechanical forming, machining, joining, welding, laser processing, plasma processing, micro- and nano-processing) makes standard materials suitable for more applications. Actual activity in this field presents a few problems connected to obtaining and processing metallic alloys, the modification of surface states, and the characterization, modeling, and simulation of prototyping technologies. Based on the multiple possibilities of applying alloys with well-established production technologies by modifying their properties through various processing methods, this Special Issue is dedicated to the results obtained through various thermo-mechanical processes, specialized treatments, sintering of materials obtained through 3D printing or other processing processes implemented at the laboratory or industrial level.

This Special Issue of the Journal of Manufacturing and Materials Processing will focus on the most recent advances in obtaining and processing materials used in the industrial, automotive, chemical, or medical fields with improved performances.

Ultra-high molecular weight polyethylene (UHMWPE) is widely used in orthopedic and prosthetic applications due to its excellent wear resistance and biocompatibility. However, its high molecular weight presents significant challenges in terms of processing and formability, particularly at the micro scale. This study investigates the flowability characteristics of a new melt-processable UHMWPE in micro-disc geometries to evaluate its suitability for advanced prosthetic applications. Micro-injection molding experiments assessed the material’s behavior under various thermal conditions. The influence of parameters such as temperature, pressure, and disc dimensions has direct effects on the flow behavior of UHMWPE and was analyzed by simulation and experiments. Results indicate that while UHMWPE exhibits limited flow under conventional conditions, optimized processing parameters can enhance discs’ formability without compromising the material’s structural integrity, avoiding defects. These findings provide critical insights for the microfabrication of UHMWPE thin components in next-generation prosthetic devices, enabling improved design precision and functional performance.
