Hydrogel Testing
Substrate Testing
The syringe is loaded and ready for printing.
We mixed gelatin slurries of weak, medium, and strong concentrations to test which could support a gel.

"In order: Concentrated Heated Gelatin 1,2; Weak Heated Gelatin 1; and Concentrated gelatin slurries (unheated gelatin) 1,2"
"Cross sections of strong slurries. The 0.96 ratio held the shape of the design best and was fluid enough to heal after extrusion. The reason the outline is faint is that the gelatin was absorbed into the surrounding slurry; this will not happen with hydrogel."
