Abstract Additive manufacturing by material extrusion offers innovative potential for component design and is driving advances in many industries. However, fully harnessing these advancements necessitates a thorough comprehension of the process-specific anisotropic structural properties. The complex interactions between process parameters their direct influence on properties often lead to discrepancies mechanical tested specimens at coupon level inherent additively manufactured components....
The fabrication of polymer–metal hybrids in an additive process makes it possible to further improve the geometrical and material adaption a multi-material design. In this work, PLA is fabricated through fused filament on AlSi10Mg structures manufactured by laser powder bed fusion. mechanical connection realised form fit, for which different geometries are examined tensile tests. Deep penetration into metallic achieved optimisation parameters. depth assessed use micro-computed tomography....
Technological advances have led to the increased use of plastic-based additive manufacturing processes for production consumer goods and spare parts. For this reason, need best possible mechanical properties while maintaining geometric accuracy is becoming increasingly important. One these Arburg Plastic Freeforming process, which differs from widely used Fused Filament Fabrication process in way that droplets are discharged along a track instead continuous extruded tracks. As with all other...
Additive manufacturing provides the ability to produce structural components featuring complex shapes in one step, compared traditional methods of production. Therefore, additive has recently gained attention for direct production parts. Using fibre reinforced filaments offers opportunity improve mechanical properties FFF printed components. In order dimension them correctly, manufactured samples based on glass were determined. Additionally, influence extrusion paths resulting a distinct...
Abstract This study presents a comprehensive simulation of the fused deposition modeling (FFF) process polylactic acid (PLA) using multiphase-field method. Compared to existing works, this work aims simulate overall FFF process. It combines temperature evolution, viscous flow, polymer crystallization, and residual strain calculations within microstructure with mechanical property analysis in single study. Simulation studies were done case layer flowing effect filament distribution...
Two serious limitations of present memory systems by using ferrite cores have been their relative bulk and narrow operating temperature range. A marked reduction in size has achieved use a “continuous wire” method inserting drive lines through planes then folding the planes. This eliminates conventional frames all solder connections between By greatly reducing number connections, new increases reliability facilitates assembly stacked typical folded stack occupies as little 2% volume its...
The mechanical properties of plastic-based additively manufactured specimens have been widely discussed. However, there is still no standard that can be used to determine such as the interfacial strength adjacent tracks and also exclude influence varying manufacturing conditions. In this paper, a proposal made using with only one track within layer. For purpose, so-called single-wall polylactide were characterised under tensile load area between layers was determined three methods. It turned...
Plastic-based additive manufacturing processes are becoming increasingly popular in the production of structural parts. Based on idea lightweight design and aim extending functionality structures, additively manufactured foam structures has emerged as a new field application. The optical characterisation these is particular importance for process adjustments identification (unwanted) changes structure. degree foaming fineness structure interest at this point. In context, only part dominated...
