In this study, production of metal/polymer composites using polyethylene as the matrix with various contents of metal powder was investigated. Fused deposition modeling (FDM) process is one of the most popular and conventional additive manufacturing methods to produce three‐dimensional (3D) specimens from computer‐aided design data with complex geometry and lower prices in comparison with the alternative methods. Given the advantages of this process, it seems inevitable for the development of new materials. Utilizing semicrystalline plastics impose challenges for producing parts due to printing issues such as distortion and warpage. In this experimental work, a compounding production line was implemented to produce composite filaments with 25, 50, and 75 wt % of copper powder suitable for the FDM process. After dealing with printing issues, flexural, electrical conductivity, and bulk density tests were done. The micrographs of the specimens were examined via scanning electron microscopy to reveal the distribution of the copper particles. It is believed that the metal/polymer filament could be used to print new 3D parts. The material could be utilized in electromagnetic structures for some specific applications, such as shielding, with new properties. Also, by solving printing problems for a semicrystalline polymer, it can be encouraging to examine printing process for other rarely used thermoplastics. © 2019 Wiley Periodicals, Inc. J. Appl.

The inherent fog collection mechanism used by the cactus gives inspirations for constructing energy‐efficient and environmentally friendly water collection devices. However, the related studies meet the bottleneck on improving the collection efficiency because it is hard to replicate real natural clusters of branched spines by traditional manufacturing methods. The immersed surface accumulation based 3D printing provides a tool to reproduce branched cactus spines, enabling the study of water collection of artificial spines with various designs. Here, a cactus‐inspired surface decorated with multiple directional artificial spines for highly efficient water collection and transportation is presented. The nanoscale hydrophobic coating is sputtered on the surface of the 3D‐printed spines to accelerate the water growth rate. The results show that the hexagonally arranged clusters enhance the moisture airflow around 3D‐printed spines, and the printed spines with 10° tip angle and hydrophobic coating achieve the highest weight gain of 2 mg min−1 mm−3. This study opens intriguing perspectives for designing next‐generation structural materials with the special spatial distribution of biomimetic features to achieve energy free and highly efficient water collection. The results reported here are believed to be helpful for the development of environmental friendly water collection, water transportation, and water separation devices.

“…The feasibility of using UAM to fabricate dissimilar metal welds has been shown. 15, 16 Truog 17 investigated the effect of post-weld heat treatment of Al–Cu UAM builds and observed an increase in the bond strengths after post-weld heat treatment. Post-weld characterisation showed the formation of a thin layer of intermetallic at the interface which provides a constraint during deformation resulting in a more energetic failure of the builds.…”

“…Previous work has shown that while welding dissimilar metal combinations such as Al-1100 and CP titanium, the deformation is primarily concentrated in the softer metal while the harder Ti does not deform. 18, 19 While the welding of metal combinations such as Al–Al, 11, 12, 20, 21 Al–Cu 17 and Al–Ti 15, 16, 18, 19 has been well studied, there are currently limited studies which address the challenges of welding steels using this technique.…”

Driven by the interest to weld steel and aluminium (Al) in the solid state to prevent intermetallic formation, 9 kW ultrasonic additive manufacturing (UAM) has been used to fabricate Al 6061-4130 steel dissimilar metal builds. In addition, Al 6061-6061 builds were fabricated using similar techniques to provide a baseline for mechanical property measurement. Mechanical testing performed using pushpin testing shows that steel-Al dissimilar metal welds fail across multiple layers while Al-Al welds delaminate from the substrate. Multi-scale characterisation indicates that the change in failure morphology is due to the formation of metallurgical bonds in the Al-steel builds. Texture analysis shows identical textures at the interface of Al-steel, Al-Al and Al-Ti joints; showing that the bond formation in all cases relies extensively on plastic deformation across multiple materials. In addition, no changes to the bonding mechanism occurred when the materials used as foils and substrate were swapped.
