Safety Notice

CAUTION: Use of controls or adjustments, or performance of procedures other than those contained in the operation, maintenance or any other manual provided with this machine may result in hazardous radiation exposure.

    NOTE: Closed radiation products are not considered to be hazardous.


The Figure 4 UV Curing Unit 350 incorporates a protective housing and radiation-protective access lid, such that there is little exposure or human access to the radiation generated by the curing chamber during normal operation. Some radiation does leak out at the lid's hinges.

All service to the UV process machine and other components requiring safety switch override, or requiring opening of panels not specified in this manual, shall only be performed by 3D Systems service personnel, their authorized agents, or personnel who have been service-trained by 3D Systems.
