Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Metallic scaffolds with 3D macroporous architecture were produced by direct-ink writing, an additive manufacturing process, which consists in: (i) ink formulation (ii) 3D layerwise extrusion (iii) debinding and sintering. An easy-handling and CMR-free metallic ink composed of aqueous gel and stainless steel powder was optimized to allow 3D extrusion when keeping stiffness and viscosity for design adequation. Evolution upon sintering under vacuum, resulting in a second-scale micronic porosity, was followed by microscopy and 3D X-ray tomography. The ductile behavior was assessed by in situ compressive test under X-Ray tomography, showing a predominant role of macropores compared to micropores in the filaments. This design method with the same hydrogel can be applied to generate other architectured structures of sinterable alloys.
