3Dresyn Research HydroGel SLA1 is a photocurable hydrogel resin system for SLA, DLP and LCD additive manufacturing in pharmaceutical and biomedical research environments.

3Dresyn® Research HydroGel SLA1 is a photocurable hydrogel resin system developed for SLA, DLP and LCD additive manufacturing in pharmaceutical and biomedical research environments, enabling controlled swelling and release behavior for advanced hydrogel research.

Designed for use in vat photopolymerization systems (SLA, DLP and LCD) within controlled laboratory environments. Suitable for hydrogel research, formulation development, and in-vitro studies involving swelling, permeability and controlled release.

This material is strictly for research and development use only. It is not a medicinal product, not a medical device, not a pharmaceutical excipient and is not approved for clinical use, human administration or commercialization.

Any translation of research results into clinical or regulated applications requires full independent regulatory evaluation, including biocompatibility, toxicological assessment, extractables and leachables studies and formal authorization by the responsible legal entity.

Hydrogel behavior is strongly dependent on hydration state, exposure conditions, geometry and post-processing. Variations in these parameters can significantly affect swelling, mechanical response and release kinetics.

Material performance, swelling behavior, permeability and release characteristics depend on the complete material–printer–process–conditioning workflow. Full validation is required for each research objective using appropriate analytical methods.

• Dedicated hydrogel system for additive manufacturing research
• Tunable swelling and release behavior
• Compatible with multiple curing wavelengths
• Suitable for thermosensitive research compounds
• Flexible formulation and processing window for R&D
