Hydrogel Testing

"Here we show the various shapes printed by the FAB@Home. Our best (and most recent) prints are shown at the right column The top row shows cylinders 0.5 cm in height, the middle row shows two cylinders 1 cm in height and one hollow cube with an open top, and the bottom row contains solid cylinders 1 cm high."

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."
