3Dresyn FR1 for fire and flame resistance

Product description

3Dresyn FR1 is a fire and flame resistant photopolymer designed for vat photopolymerization 3D printing.

This ultra hard and rigid material is formulated for excellent fire and flame resistance, elevated heat deflection temperature, very high rigidity and high mechanical strength in professional SLA, DLP and LCD workflows.

Application framework

Designed for use in vat photopolymerization systems (SLA, DLP and LCD) within professional and industrial environments for manufacturing ultra hard and rigid parts requiring fire and flame resistance.

Typical applications

• Fire and flame resistant rigid technical components
• High heat resistance printed parts
• High resolution functional rigid parts
• Colored fire retardant printed components

Measured mechanical properties

• Tensile strength: >40 MPa (ISO 527-1 / ISO 527-2)
• Flexural strength: >40 MPa(ISO 178)
• Young’s modulus: MPa (ISO 527)
• Elongation at break: <1% (ISO 527)
• Shore hardness: D85-90 (ISO 868)

Measured physical properties

• Viscosity: <3000 mPas at 23°C ± 2°C (ISO 3219)
• Heat deflection temperature: up to 290C @0.45MPa (ISO 75)

Functional performance characteristics

• Excellent fire and flame resistance, FR grade, which under heating decomposes in non toxic solid residues and water, absorbing heat, releasing vapor and making a natural barrier against oxygen and heat
• Available in clear, white and in any color
• Ultra Hard and Rigid (UHR)
• Eco friendly and ultra safe fire and flame retardant, based on natural raw materials
• Very high hardness and rigidity
• Durable
• Very high resolution
• Broad range of basic and special colors
• Select your custom color (RAL/NCS)

Processing and handling performance

• Printable by most commercial and professional SLA, DLP & LCD 3D printers
• Increased durability of the resin tank
• Suggested postprocessing conditions for optimum overall performance

Chemical and safety characteristics

• Eco friendly and ultra safe fire and flame retardant
• Based on natural raw materials
• Organo-tin free

Testing & processing disclaimer

Fire and flame resistance performance depends on your printer specifications. A High Viscosity HV version of 3Dresyn FR1 with an increased concentration of the fire and flame additives can be sent if your printer has a heating system. Final fire performance, mechanical properties and printability must be validated by the user according to the intended application and processing conditions.

Disclaimer

This material is supplied as a professional manufacturing material and is not marketed as a finished medical device. Final part performance and suitability must be validated by the user according to the intended application.
