... of a thermostable yield-stress fluid made from fumed silica particles and sunflower oil. By tuning the rheological properties of the support bath, thermoplastic filaments were effectively supported in a molten state throughout printing. Biocompatible and biodegradable polycaprolactone (PCL) was selected...

... microfluidic devices. This study aims to investigate a fumed silica-PDMS suspension that can function as a matrix bath for embedded 3D printing (e-3DP) purposes, making it technically feasible to print microfluidic chips with complex embedded channels via low-cost extrusion 3D printing. The rheological...
