Nexa3D&Henkel xFLEX475
Nexa3D xFLEX475
Nexa3D xFLEX475 is an industrial strength UV resin that cures to a soft, elastomeric material.
xFLEX475 is suitable for applications where resilience, snap back, and tear resistance is desired, such as lattice structures and functional prototyping. This single component resin is easy to print, making it a superior material for elastomeric applications.
General Information
Mechanical Properties
Limitations
The mechanical and physical properties of Nexa3D xFLEX475 are highly dependent on the printing parameters used as well as part geometry. It is common that validated workflows need to be adjusted for unusually thick or thin geometries. Even if the properties observed in your lab don’t match the TDS, it does not signify that something is “wrong,”. Parts may be tacky prior to post-cure.
