Among various 3D printing technologies, VAT photopolymerization offers high manufacturing accuracy and speed, making it well-suited for the manufacture of complex structures. Therefore, it shows great potential in improving the structural fineness of ceramic components.

Although metal-salt-based DESs enable coordination reinforcement, how ligand identity regulates coordination environment, phase behavior, and interdomain connectivity remains unclear. Here, we show that ligand-controlled coordination dictates both network formation and phase behavior in intrinsically phase-separating eutectogels. Using poly(N-isopropylacrylamide) (PNIPA) and ZnCl₂-based DESs with acetamide (AcAm) and ethylene glycol (EG) as ligands of distinct coordination strength, two regimes are identified. In PNIPA/ZnCl₂–AcAm, weak Zn²⁺–AcAm coordination enables Zn²⁺ bridging between polymer chains, suppressing phase separation and forming a homogeneous network with uniform polymer–Zn²⁺ interactions, high transparency (&gt; 90%), high elongation (2553%), and tensile strength of 5.21 MPa. In contrast, PNIPA/ZnCl₂–EG shows strong Zn²⁺–EG coordination, limiting polymer–metal interactions and inducing coordination-stabilized phase-separated domains with reduced transparency (~50%), higher strength (14.45 MPa), and limited elongation (85%). Non-coordinating choline chloride DESs yield weak networks (&lt; 1.3 MPa), confirming that coordination-governed connectivity dominates reinforcement. A mixed-ligand system ([AcAm]/[EG] = 1:2) achieves balanced strength (7.67 MPa) and elongation (1270%).
