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.
The following working curve values were determined using a NXE400 printer.
- 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 3843-xABS Black 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
