Nexa 3D and Henkel have partnered yet again to create the single-component xFLEX402-Black 3D printing resin. This material is a semi-firm rubberlike elastomer that produces durable parts with high rebound, great elongation at break (230 %), excellent tensile strength and high energy return (30-35 %).

The xFLEX402-Black resin is optimized to be used on the Nexa 3D printers, including the first Nexa 3D desktop solution - the ultrafast 4K XiP printer that uses the patented Nexa 3D LSPc technology to deliver highly accurate parts with great surface properties and isotropic properties.

Thus, prototypes and end-use parts for many sectors (footwear design and production, tools, etc) can be 3D printed with the xFLEX402 resin, with fast and reliable results guaranteed for a more agile and independent production workflow and supply chain.

Parts 3D printed with the Nexa 3D xFLEX402 resin will achieve their specific properties only after being subjected to post-processing by washing and curing. If applicable, the support structures must be removed from the part before curing and the part must be washed. The xFLEX402 resin is a plant-based material which allows for washing the 3D printed parts in water, combined with soft brushing. This means that no IPA alcohol or other substances are needed for the washing of this material but the Nexa 3D xClean can be used.

Once washed, the parts 3D printed with the xFLEX402 resin must be dried and then cured either with the help of an LED or wide spectrum lamp, or in the Nexa 3D Wash+Cure station developed especially for the washing and curing of parts 3D printed on the XiP 3D printer. The recommended washing, drying and curing times can be consulted on the manufacturer's website for each Nexa 3D resin.

Certain precautions must be taken when working with 3D printing resins. The user must ensure that the working space is adequately ventilated, and that protective goggles, gloves and garments are worn at all times. The xFLEX402 resin should be stored in a tightly closed container/resin vat to avoid resin deterioration due to UV exposure. The container/vat should be kept in a cool, well ventilated area away from heat, sparks and open flame.
