1. Overview
1.1. Safety Warnings
Danger: Read this operation manual prior to using the NXE400 printer.
Failure to do so can result in injury or death.
Caution: Do not modify the NXE400 without factory authorization.
Modifications to the NXE400, including the override of safety features or
interlocks, can result in damage to the printer or injury to operators.
Unauthorized modifications invalidate your warranty.
Caution: Use appropriate protective equipment when handling resin and
solvents, including cut & abrasion resistant gloves, safety goggles, smock,
and vapor respirator if recommended by SDS of resin or solvent.
Caution: The NXE400 light engine emits UV-A radiation which can damage
eyes or skin with prolonged exposure. Use protective glasses rated for 99.9%
UVA protection when working around the NXE400 or post-cure equipment.
Warning: It is the user responsibility to verify suitability of material and
process for application requirements. In no case shall Nexa3D be liable for
loss, death, or injury caused by products produced on Nexa3D printers or
with Nexa3D materials. Nexa3D expressly disclaims any implied or explicit
warranty of fitness for any particular usage.
Warning: Immediately clean spilled resin from the printer, or it may cure
and cause surface damage when removed. Most surfaces may be cleaned
with IPA or other similar solvents (Yellow Magic 7, Window Cleaner, xClean).
