1. A method for additive manufacturing, the method comprising:
forming a printing mixture, the printing mixture comprising one or more polymers and one or more solvents;
disposing a volume of the printing mixture into a yield-stress support bath; and
allowing the printing mixture to partially coagulate in the yield-stress support bath.
