Rapid, voxel-based 3D printing with yield-stress fluid inks.

Direct ink additive lithography (DIAL) enables rapid, voxel-based, support-free 3D printing with yield-stress inks, achieving kilopascal-scale rheology-compatible fabrication.

• Why it matters: 3D printing remains limited by trade-offs among printable materials, resolution, speed, and part size, especially for yield-stress complex fluid inks.
• What they did: DIAL merges translational photopatterning with ink sheet deposition, and rheology is tested using model inks with kilopascal-scale yield stresses, benchmarked against DLP and DIW.
• The result: DIAL is shown to support fast, high-throughput, large-area printing and is used to produce multiscale architected, multimaterial, structural electrolyte, and hydrogel structures that are difficult or impossible with current methods.
