Al encapsular esos polímeros dentro de partículas en agua, el método abre la puerta a piezas más duras y flexibles para industrias como la de envases, calzado o dispositivos médicos.

High-molecular-weight polymers provide entanglement, toughness and thermoplastic or elastomeric behaviour, but their solutions and melts commonly become too viscous for conventional VPP. Polymer latexes provide a different materials architecture: the high-molecular-weight chains are confined inside pre-existing colloidal particles, while the continuous liquid phase remains comparatively low in viscosity. In the demonstrated latex route, water-soluble monomers, oligomers or crosslinkers in the continuous phase form a temporary or permanent photocured scaffold around the particles. This scaffold fixes the printed geometry and creates a particle-embedded green body. Drying and thermal post-processing then remove the aqueous ca","pubDate":"2026-10-22T17:39:30Z","url":"https://doi.org/10.5281/zenodo.22123334"},"indexado":"2026-10-24T00:38:06.113Z"}}
