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.
- Directions for use
- This product is light sensitive; exposure to daylight, UV light and artificial lighting should be kept to a minimum during storage and handling.
- Shake or stir Nexa3D xCE-White well before use.
- Agitate resin before each print.
- Do not leave resin in printer tray when not in use.
- Recommended Post Print Processing
- Rinse the printed part using an approved cleaner to remove uncured resin
- The use compressed air or impregnated wipes to remove excess residual solvent from the surface is recommended
- Remove any support structures prior to any post-curing step

Technical Details & Test Data
- 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 post-cured 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.
Chemical Results Tap water < 0,23% Salt water (5 w% NaCl) 0,39% Ethanol 0,47% Dipropylene glycol methyl ether 0,23% Dimethyl sulfoxide (DMSO) 0,31% Tripropylene glycol monomethyl ether 0,16% Diesel < 0,1% Petrol < 0,1% Bleach (5w% NaOCl) < 0,1% Methyl Ethyl Keton (MEK) < 0,1% Vinegar (8 w%) < 0,1% Hydrochloric Acid (0,1 M pH1) < 0,1% Sodium Hydroxide (1 M pH14)* < 0,1% * Sodium Hydroxide had a soft outer surface.
