ThePrimaCreator Value Flex UV Resin 1000ml - Blackis the ideal resin for those seeking extraordinary flexibility, strength, and precision performance in 3D printing. Thanks to a formula optimized for LCD, DLP, and SLA printers with a 395–405nm UV light source, it allows for printing elastic, impact-resistant, and highly detailed objects. It is perfect for models requiring resilience, the ability to bend without breaking, or shock absorption, such as gaskets, flexible mechanical components, handles, covers, and functional prototypes.
The surface of the models is opaque, smooth, and with sharp details: the special mix of Value Flex allows the printed object to achieve exceptional elongation at break (up to 130%), optimal hardness, and superior impact resistance compared to standard resins. The overall printing experience is simple and fast thanks to short curing times: the resin hardens in a few seconds under UV light and can be quickly post-cured.
