Safety Notice

CAUTION: Use of controls or adjustments, or performance of procedures other than those contained in any official manual for this machine, may result in hazardous radiation exposure.

    NOTE: Closed light-projection products are not considered to be hazardous.


The NextDent 5100 printer incorporates a protective housing and radiation-protective lid, such that there is no exposure or human access to the radiation generated by the light projector during normal operation. The print engine was evaluated to IEC 62471 and classified as Risk Group 2. This means the UV light is only a moderate risk and does not pose a hazard due to aversion response to bright light or thermal discomfort. However, it is still good practice not to stare directly into the projector, particularly when running the machine with an empty resin tray.

All service to the light-projection process machine, the embedded light-projection system, and other components requiring sensor override shall only be performed by 3D Systems Corporation service personnel, their authorized agents, or personnel who have been service trained by 3D Systems Corporation.
