3Dresyn SAE1 is our Swellable Absorbent and Elastic Hydrogel resin

3Dresyn® SAE1 is a swellable absorbent photopolymer developed for SLA, DLP and LCD additive manufacturing, enabling the fabrication of elastic hydrogel structures that become softer and more absorbent after immersion in water or alcohol.

Designed for use in vat photopolymerization systems (SLA, DLP and LCD) within controlled professional and research environments. Suitable for hydrogel structures, scaffold fabrication and applications requiring soft elastic behavior after swelling.

• Water- and alcohol-swellable hydrogel materials
• Soft gels and jelly-like elastic hydrogel structures
• Hydrogel scaffolds for tissue engineering research
• Complex and customizable absorbent structures
• High dielectric permittivity elastomer research systems

• Tensile strength: <2 MPa before dipping / <0.2 MPa after dipping (ISO 527)
• Flexural strength: <2 MPa before dipping / <0.2 MPa after dipping (ISO 178)
• Young’s modulus: <2 MPa before dipping / <0.2 MPa after dipping (ISO 527)
• Elongation: >100% before dipping / >>200% after dipping (ISO 527)
• Shore hardness: A20 before dipping / O30 after dipping (ISO 868)

• Very low viscosity: <20 cps (Brookfield)

• Recommended for printing water- and alcohol-swellable absorbent hydrogel 3D materials
• Ideal for making soft gels or jellies / elastic hydrogel materials with Shore O30, which cannot be directly 3D printed due to their excessive softness and resilience
• Ideal for intricate, complex and highly customizable scaffold structures that can support cell adhesion and promote cell infiltration for tissue engineering 3D and for printing hydrogel scaffolds
• Absorbs more than 2–3 times its weight of water and/or alcohol without losing its original shape
• Ideal resin for designing high dielectric permittivity elastomers since it admits water (permittivity of water is εr = 80 at 20ºC and 1 kHz)
• Elastic with elongation >>200% after overnight dipping in water and/or alcohol (ISO 527)
• Medium hard, soft and flexible before dipping
• Fast swelling in water and alcohol
• Tack-free finishes after light box post-curing
• Flexible material that swells and becomes very soft while keeping its original shape
• High resolution
• Metal- and organo-tin free formulation

• Printable by most commercial and professional SLA, DLP and LCD 3D printers
• Fast printability even with low power LCD printers
• Increased durability of the resin tank
• It can be combined as you wish with 3Dresyn NS1 for choosing your optimum final consistency after dipping

The final mechanical behavior depends on swelling conditions, solvent type, immersion time and geometry. Swelling induces a transition from an elastic printed state to a softer hydrogel state while preserving the original shape.

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

• Elastic absorbent hydrogel material for advanced soft structures
• Water- and alcohol-swellable behavior with shape retention
• Suitable for scaffold design and hydrogel research
• Useful for high dielectric permittivity elastomer development
• High resolution and very low viscosity for precise printing
• Compatible with SLA, DLP and LCD technologies

This material is supplied as a professional manufacturing and research material and is not marketed as a finished product. Final performance, swelling behavior and application suitability remain the responsibility of the user.
