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-projection products are not considered to be hazardous.


The Figure 4 Modular Printer incorporates a protective housing and radiation-protective access doors, such that there is no exposure or human access to the radiation generated by the radiation projector during normal operation. The print engines were evaluated to IEC 62471 and classified as Risk Group 2. This means the optical radiation 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 a projector, particularly when running the machine with empty resin trays.

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