Exceptional heat resistance: HDT > 220°C (up to 227°C at 0.455 MPa), with an upper temperature limit exceeding 250°C. Excellent stiffness: Flexural modulus of 4321 MPa. Moderate toughness: Balanced mechanical properties with impact strength of 16 J/m. Superior accuracy and surface quality: Ideal for applications requiring high precision and reliable surface finish. Fast and easy processing: Compatible with large-format SLA printers for efficient production.

Brittleness: Like most rigid UV-curable resins, it is more brittle than thermoplastics like PA12 or PA12+GF, making it less suitable for parts requiring high impact resistance or flexibility. Post-treatment required: Heat deflection temperature of 227°C is achieved only after simple post-treatment (e.g., thermal curing). Limited toughness: Moderate toughness but not suitable for high-impact or high-stress applications. UV sensitivity: As a photopolymer, it may degrade under prolonged UV exposure without proper coating or protection. Viscosity: Relatively high viscosity (276 cps @ 30°C) may require careful handling during printing.

UFSH220 is a high-temperature UV-curable resin for SLA 3D printing, offering exceptional heat resistance (HDT > 220°C) and excellent mechanical properties. It combines high stiffness (4321 MPa flexural modulus) with moderate toughness, along with superior accuracy and surface quality. This material is especially recommended for applications requiring thermal stability and precision, such as wind tunnel components, impellers, motor parts, and rapid tooling. It is optimized for fast, easy processing on large-format SLA printers.
