Pluronic is great sacrificial material due to its reverse gelation. It is a gel at room temperature and liquifies at colder temperatures.
Gelatin Methacryloyl (GelMA)

GelMA is produced through the modification of gelatin with methacrylic anhydride. The amino groups on gelatin's side chains are replaced with methacryloyl groups. The final product is able to crosslink in the presence of a photoinitiator (LAP) and UV light.

Sodium Alginate

This substance is a natural polymer derived from algae and is capable of ionic crosslinking in the presence of divalent cations. The most common crosslinking method is submerging in a bath of CaCl2 solution.
