Hydrogel‐Based Vat Photopolymerization of Ceramics and Metals with Low Shrinkages via Repeated Infusion Precipitation

Advanced Materials, EarlyView.
This work introduces an in situ precipitation strategy for the hydrogel‐based vat photopolymerization of architected ceramics and metals with reduced shrinkages and improved densities. Repeated infusion‐precipitation significantly increases metal loading within the hydrogels, which improves part quality after thermal conversion.
