Composite Extrusion Modeling (CEM) is a screw-based material extrusion (MEX) additive manufacturing process that can produce plastic, metal and ceramic parts based on standard injection molding feedstocks. In this work, an aluminum oxide feedstock (Al2O3) originally developed for processed via MEX the first time by depositing plasticized in layers build platform. order to identify appropriate parameters, characterized estimate printable temperature processing window. Initially, best values...
Composite extrusion modeling is an advanced material additive manufacturing process that requires fine-tuning of printing parameters for injection molding feedstocks. In order to achieve comparable high-quality parts at different layer thicknesses, the must be optimized respective thicknesses. this work, AISI 8740 low-alloy steel are four The multiplier values each thickness tuned, allowing fine adjustment printer's screw rotation speed every thickness, resulting in all final parts' maximum...
Abstract Endoprostheses such as hip replacements are subject to wear. Lubrication of the joint interface plays a key role in wear process, but mechanisms lubrication is challenging understand. The main issue three-body abrasion which leads shorter life cycle. In order improve cycle, surfaces articulating components can be modified, for example by pulsed femtosecond-laser microstructuring. By microstructuring implant surface, viscosity synovial fluid between increased due non-Newtonian...
The microstructuring of surfaces is a highly researched field that aimed at enhancing the tribological behavior sliding such as artificial joints, which are subject to wear. Lubrication joint interface plays key role in wear process, although mechanisms lubrication quite complex. In order improve lubrication, articulating components can be modified by pulsed femtosecond-laser microstructuring. Through microstructuring, apparent dynamic viscosity synovial fluid between increased due its...
Due to the rapid spread of novel coronavirus SARS-CoV-2 (COVID-19), medical protective equipment is in high demand. In order cover need for these materials, frames face shields, instance, can be produced flexibly, quickly and decentrally small quantities through 3D printing. this study, Fused Deposition Modeling (FDM) used production corresponding components from Polylactide plus (PLA+) Polyethylene terephthalate glycol (PETG) material. Stereolithography (SLA) also produce high-quality a...
Abstract Electrospinning has emerged as a versatile technique for producing nanofibers diverse applications. The fibers produced are highly regarded their biocompatibility, exceptional surface-to-volume ratios, porosity, and adjustable composition properties, making them promising scaffolds tissue engineering. In the literature, annatto-loaded cellulose acetate already been successfully used electrospinning. However, N,N-dimethylformamide (DMF) was utilized solvent in experiments, which is...
