TL;DR: In this paper, three dimensional scaffolds with controlled pore architecture were prepared from 45S5 Bioglass powders by robocasting (direct-writing) using carboxymethyl cellulose (CMC) as the single processing additive.

TL;DR: In this paper, aqueous suspensions containing 45vol% of 45S5 Bioglass were successfully prepared using carboxymethyl cellulose (CMC) as a single multifunctional (dispersant, binder, gelation agent) processing additive.

TL;DR: In this paper, the effect of polymer infiltration on the mechanical properties of 13-93 bioactive glass scaffolds fabricated by robocasting has been investigated, and it was found that the mechanical enhancement achieved upon impregnation on robocast 13- 93 structures with fully-dense struts was lower than in the currently existing literature due to the absence of microporosity.

TL;DR: Robocasting and pressureless spark plasma sintering are combined for the first time to fabricate geometrically-complex B4C components as discussed by the authors, and the usefulness of cold-isostatic pressing to improve the densification of the pieces is evaluated, and the benefits of robocasting over conventional dry powder compaction are identified.

TL;DR: In this article, the influence of powder milling environment (water or ethanol) on sintering, mechanical and biological performance and in vitro degradation behavior of the fabricated scaffolds was investigated.
