Nexa3D xCE-Black

Nexa3D xCE-Black, a high-performance polymer for producing end-use plastic parts and injection molding tools inminutes. This new material is a single cure polymer that delivers higher flexural strength that is typically achieved only in dual cure cyanate ester resins. xCE-Black has excellent isotropic properties and exhibits long-term environmental stability making itwell suited for a variety of automotive parts,electronics and many industrial components as well as the production of injection molding tools.

Storage Information

Store product in the unopened container in a dry location.; Storage information may be indicated on the product container labeling.; Optimal Storage : 8°C to 21°C.; Storage below 8°C or greater than 28°C can adversely affect product properties.; Material removed from containers may be contaminated during use. Do not return product to the original container. Nexa3D cannot assume responsibility for product which has been ontaminated or stored under conditions other than those previously indicated.

Chemical Compatibility

Compatibility of 3D-printed and post-cured resin parts were tested with several chemicals. From several resins, blocks of 20 x 20 x 20 mm were printed and postcured according to the table below. The weight of the blocks were measured before the test and after 24 hour immersion in the specific chemical solution. Before weighing the surface of the immersed blocks were wiped dry.. * Sodium Hydroxide had a soft outer surface.

3D Printing Machine Settings

Cure rate and ultimate depth of cure depend on light intensity, spectral distribution of the light source, exposure time and light transmittance of the printer window through which the light must pass.
