The xESD resin from the Nexa 3D family of functional materials is a black rigid material with static-dissipative properties. The xESD resin is made of a rigid urethane dimethacrylate base with uniformly dispersed discrete carbon nanotubes.
Parts 3D printed with the xESD resin do not mark, and their isotropic static dissipative performance is combined with improved tensile strength, tensile modulus and impact resistance thanks to the addition of carbon.
The xESD resin was designed especially for the Nexa 3D ultrafast resin 3D printers, including the XiP 4K printer. The patented Nexa 3D LSPc technology allows for the fabrication of high resolution dissipative parts in a matter of a few hours.
Numerous industries where electrostatic discharge poses a threat, especially the electronic industry, can benefit from the advantages offered by the Nexa 3D xESD resin. It is a perfect material for the 3D printing of ESD-safe jigs, fixtures, grippers, assembly aids and enclosures, and thus protecting high value electronic components from ESD damage.

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 xESD 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.
Parts 3D printed with the Nexa 3D xESD 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. Nexa3D recommends 2 wash intervals (2 minutes each) in IPA alcohol or xClean. It is recommended to use two buckets in the cleaning process, especially when working with multiple resin colors, to prevent resin residue from sticking to the part.
Once washed, the parts 3D printed with the xESD 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.
