Abstract
Lattice structures of 100Cr6 steel were manufactured from metallic-based inks by robotic-assisted deposition (robocasting) using Pluronic F-127 solution. The stability and pseudo-plastic behavior of the ink were optimized, and allowed printing through 200–840 µm nozzles, leading to macroporous architectures composed of 300–600 µm diameter rods separated by 90–350 µm pores, after debinding and sintering. A second level of porosity (sub-micron size) was controlled by adjusting the sinteri...
