In various aspects, a polymer resin is provided for vat photopolymerization. The resin can include a polyamic acid salt formed from the addition of a photocrosslinkable amine to a polyamic acid. The resin can include a photoinitiator suitable for initiating crosslinking of the photocrosslinkable amine when exposed to a light source of a suitable wavelength and intensity. The polyamic acid can be formed, for instance, by the addition of a diamine to a suitable dianhydride. Methods of additive manufacturing using the resins are also provided.
