UL-94 V0 flame retardant certification: Meets stringent safety standards for flame resistance. Halogen-free and environmentally friendly: Safe for use in various applications. Excellent toughness: Elongation at break of 35% and impact strength of 18 J/m. Superior accuracy and good surface quality: Ideal for detailed and precise parts. Large-format SLA compatible: Suitable for large-scale printing projects. Good dimensional stability: Low warpage and reliable mechanical properties.

Low heat resistance: HDT is only 53 °C @ 0.455 MPa, making it unsuitable for high-temperature applications. Moderate mechanical strength: Tensile strength (28 MPa) and flexural strength (38 MPa) are relatively low compared to engineering-grade materials. Higher viscosity: At 1250 cps @ 30 °C, it is more viscous than many other SLA resins, which may require careful handling. Limited application scope: Best suited for non-structural, aesthetic, or flame-retardant parts rather than load-bearing applications.

FR42 is a flame-retardant, halogen-free UV-curable resin for SLA 3D printing, certified to UL-94 V0 at 2.5mm thickness. It offers a unique combination of excellent toughness (35% elongation at break), superior accuracy, and good surface quality. This material is especially recommended for applications requiring flame retardancy, such as in home appliances, electronics, and transportation industries. It is the first flame-retardant material available for large-format SLA printing, making it ideal for producing large, safe, and detailed parts.
