Additive manufacturing (AM) of polyetheretherketone (PEEK) biomaterials using the material-extrusion (MEX) method has been studied for years. Because challenging process, precisely controlling printing parameters is crucial. This study aimed to investigate effects such as orientation and position on mechanical properties. Thus, 34 samples were printed PEEK filament MEX process. Samples divided ...

Abstract The development of sustainable and functional biocomposites remains a robust research industrial claim. Herein, the efficiency using eco-friendly biochar as reinforcement in Additive Manufacturing (AM) was investigated. Two AM technologies were applied, i.e., vat photopolymerization (VPP) material extrusion (MEX). A standard-grade resin VPP also biodegradable Polylactic Acid (PLA) MEX ...

We present a non-local thermodynamic equilibrium retrieval scheme for atmospheric composition and its application to Mars CO2 infrared limb emissions as measured by the OMEGA instrument on board Express (MEx). These are caused fluorescence of solar radiation, thus accounts non-LTE processes. analyzed dayside observations from selection three orbits or data qubes. Before was applied, we performe...

Material Extrusion (MEX) is an advanced technology for polymer 3D printing and countless printers are commercially available. MEX has also been demonstrated ceramics. For that purpose, thermoplastic binders filled with high loads (>40 vol%) of a ceramic powder. The printed parts subsequently debound sintered. In contrast to most printers, the printer presented herein works granulated feedstock ...

Abstract 3D printing technologies, such as material extrusion (MEX), hold the potential to revolutionise manufacturing by providing individuals without traditional capabilities with powerful and affordable resources. However, widespread adoption is impeded lack of user-friendly design tools due necessity domain-specific expertise in computer-aided (CAD) software overwhelming level freedom affor...

The Mars Express (MEX) mission has been successfully operated around since 2004. Among many results, MEX provided some of the most accurate astrometric data two moons, Phobos and Deimos. We present new ephemerides moons benefitting from all previously published to recent SRC data. Observations 1877 until 2018 including spacecraft measurements Mariner 9 were included. Assuming a homogeneous inte...

Previous missions underlined the complex influence of crustal magnetic fields on Martian environment, including plasma boundaries. Their bow shock is however poorly constrained, with most studies showing North/South differences attributed to fields, various conclusions from little strong variabilities. We analyze for first time in detail location based a multi-mission analysis (MAVEN and MEX). ...
