3Dresyn NS1 is our Non-Swellable Hydrogel resin

Product description

3Dresyn® NS1 is a non-swellable hydrogel photopolymer developed for SLA, DLP and LCD additive manufacturing, enabling the fabrication of rigid absorbent structures that absorb water, alcohol and other polar media with insignificant swelling while maintaining original size and shape.

Application framework

Designed for use in vat photopolymerization systems (SLA, DLP and LCD) within controlled professional and research environments. Suitable for hydrogel structures, absorbent materials and applications requiring fluid uptake without dimensional expansion.

Typical applications

• Water- and alcohol-absorbent non-swellable hydrogel materials
• Rigid detailed structures requiring fluid absorption without swelling
• Absorbent scaffold and hydrogel research systems
• High-resolution absorbent functional parts
• Customizable absorbent systems with controlled final consistency

Measured mechanical properties

• Shore hardness: D80 after printing, with minor decrease of surface hardness after dipping in water (ISO 868)
• Tensile strength: <40 MPa before dipping (ISO 527)
• Young’s modulus: >2000 MPa (ISO 527)
• Elongation: <8–12% before and after dipping (ISO 527)
• High resolution

Functional performance characteristics

• Recommended for printing water- and alcohol non-swellable hydrogel 3D materials
• Absorbs water and alcohol with insignificant swelling
• Hard and tough HT behavior after printing
• Fast absorption of water, alcohol, polar fluids and polar gases
• Tack-free finishes after light box post-curing
• High rigidity to permit printing of thin rigid detailed parts
• Non-brittle material that absorbs water and alcohols without swelling while keeping its original size and shape
• Fast printability even with low power LCD printers

Processing and handling performance

• Printable by most commercial and professional SLA, DLP and LCD 3D printers
• Increased durability of the resin tank
• Design a hollow structure to speed up the absorption of water or alcohol
• It can be combined as you wish with 3Dresyn SSA1 for choosing your optimum final consistency after dipping

Processing note

The final absorption behavior depends on geometry, wall thickness, immersion medium and conditioning time. Hollow structures can accelerate the uptake of water or alcohol while preserving dimensional stability.

Testing & processing disclaimer

Material performance, absorption behavior and final mechanical properties depend on the complete material–printer–process–conditioning workflow. Full validation is required for each specific application.
