In this paper, a biobased binder mainly composed of polylactic acid (PLA) was developed for the production Ti6Al4V feedstock suitable 3D printing via material extrusion. printed samples were debound solvent and thermal treatments successfully sintered in reducing atmosphere obtaining dense metallic components. The designed produced bio-binder is completely eliminated during debinding processes leading to showing high densification (93–94%), with microstructure primary alpha phase segregated...
In the realm of material innovation, remarkable versatility thermoplastic-based highly filled composites emerges as a pivotal advantage for fabricating metal parts, seamlessly integrating design flexibility. This study delves into fusion and manufacturing, spotlighting convergence extrusion additive manufacturing (MEX) injection moulding (MIM) processes through adept utilization three distinct in-house developed copper-feedstocks. Each feedstock had different composition that influenced...
Strain monitoring is of great interest in order to check components structural life, prevent catastrophic failures, and, possibly, predict residual life case unexpected events. In this study, strain sensing epoxy-based coatings containing carbon nanotubes (MWCNTs), graphene nanoplatelets (GNPs), and a mix the two (MWCNT+GNP) have been produced, with same initial electrical resistivity, applied on glass fiber reinforced composites. Morphological, mechanical, tests then performed evaluating...
This work aims to better understand the type of thermoplastic binders required produce highly loaded copper filaments that can be successfully printed via low-cost filament-based material extrusion (MEX). Compounding feedstock with 55 vol.% and three multi-component binder systems has been performed. The MEX behavior these feedstocks was evaluated by depositing at different speeds appropriately selecting temperature depending on composition. rest parameters remained constant evaluate...
Abstract In this work, polyether‐ether‐ketone (PEEK) – magnetite nanocomposites, having filler content of 50, 60, and 70 wt%, have been developed 3D‐printed via Fused Filament Fabrication to manufacture high‐performance space‐compliant soft magnetic parts. The nanocomposites present high thermal stability transition temperatures typical the PEEK matrix. Mechanical properties show increased stiffness up 12.6 GPa elastic modulus, but reduced tensile strength ductility due ceramic nanofiller....
Background: Osseointegrated implants are essential for rehabilitating edentulous patients, but critical bone defects remain challenging. Guided regeneration (GBR) with barrier membranes is an effective approach. This study evaluated a 3D printed membrane made from acrylated epoxidized soybean oil (AESO) combined xenogeneic graft GBR in critical-size defects. Methods: Forty-eight male Sprague Dawley rats (150 g) were assigned to four groups: negative control group (NC, blood clot only),...
Abstract Thermally conductive but electrically insulating polymer matrix composites are of great interest in many engineering applications such as thermal management (i.e., heat sinks microelectronic packaging, cooling mechatronic components and mechanisms). Among possible functional fillers, hexagonal boron nitride seems to be one the most promising choice due its high conductivity, this work, it was used filler polyamide 6 matrix. The resulting were first prepared form pellets, extruded...
Laser-induced graphene (LIG) is an emerging manufacturing technique for engraving patterns on precursor substrates. LIG has great potential applications to flexible eco-friendly and wrapping electronics devices, such as on-skin sensors antennas human body physiological monitoring. Moreover, LIG-made electronic labels could be embedded into innovative food packages reduce contamination waste. As the so-obtained conducting traces form a non-homogeneous partly volatile structure, it strongly...
In this paper, a hybrid commercially available alumina/polymer filament was 3D printed and thermally treated (debinding sintering) to obtain ceramic parts. Microscopic spectroscopic analysis used thoroughly characterize the green sintered parts in terms of their mesostructured, as well flexural properties. The samples show an α alumina crystalline phase with mean density 3.80 g/cm3, tensile strength 232.6 ± 12.3 MPa, Vickers hardness 21 0.7 GPa. thermal conductivity value at room temperature...
In this paper a acrylated epoxidized soybean oil (AESO) based photo-curable resin loaded with 0.25% by weight of single walled carbon nanotubes (SWCNT) was produced to manufacture biobased, self-monitoring and biodegradable materials via 3D printing digital light processing (DLP). The CNT addition plays role in providing properties, however they affect the process as absorb UV radiation which has be compensated increasing exposure time. printed samples show good dimensional/geometrical...
