3D Systems, Inc. p/n 77-D005 Rev_A 3 SAFETY GUIDELINES & INSTRUCTIONS GENERAL GUIDELINES Before using your SLS equipment, your company should have a safety program in place . The safety program should: • Point out hazardous equipment, materials, and procedures. • Explain what to do in case of an emergency. • Provide information about the hazards of the equipment and materials in the form of Safety Data Sheets (SDS). The Safety Data Sheets are provided with all materials supplied by 3D Systems. All SLS equipment is designed with safety in mind . However, improper use, malfunctions, and excessive exposure could cause injury . TRAINING AND INSTRUCTIONS Follow these general safety guidelines when operating any SLS equipment: • Do not operate any SLS equipment before receiving proper training. • Read and follow all operating instructions. • Follow all safety rules in this section and heed all hazard warnings in this guide. • Do not try to perform any equipment maintenance procedures you were not trained to do. • Operators are trained to operate the system and perform all the necessary tasks to print a part.
3D Systems, Inc. p/n 77-D005 Rev_A • Certified service personnel are those who have completed the 3D Systems service training package and are certified to perform service tasks. Certification may occur at various levels, and servicers should only perform tasks they are authorized and certified to complete. MACHINE HANDLING • Do not try to access, service, or adjust any components inside any SLS equipment enclosure. • Do not try to open any panel or door while a machine is running. • Do not access any area of the machine near the print chamber during printing. • Use special caution when handling a heated print cake and when dealing with the heated, inert environment inside the SLS system’s print chamber. Take note of all thermal hazard warning labels on the machines. • Secure electrical cables and coolant hoses to prevent tripping. MATERIAL HANDLING • Do not use any material without first reviewing its Safety Data Sheet (SDS). • To prevent injury and equipment damage, be sure to follow all handling guidelines detailed in the appropriate Material Guide. ALARMS AND WARNINGS • If you see an error, alarm, or warning message on any SLS equipment display, note the state of that machine’s stack light. Clear the alarm, error, or warning message before resuming operation. • Displayed error, alarm, or warning messages can result from unsafe practices, such as opening an enclosure door or panel when equipment is powered up and running. SAFETY SYMBOLS AND DEFINITIONS The following safety labels are posted at various points on the machine to indicate potentially hazardous conditions: HOT SURFACES HAZARD: There are surfaces and materials in the vicinity that may be hot and could cause severe burns. ELECTRIC SHOCK HAZARD: High voltage electricity is accessible in the vicinity of this sign or behind the access panel. High voltage can cause severe burns or death.

If someone has difficulty breathing or a “loss of breath” sensation, transport the person to a well-ventilated room or outside of the facility . If the condition persists, seek immediate medical attention . SLS EQUIPMENT SAFETY FEATURES A major design goal for all SLS equipment is to provide a safe operating environment . The frame and enclosure designs passively limit hazardous access while the electronics and software actively and automatically sense and react to unsafe conditions when they arise . For example, if the SLS system detects unsafe operating conditions, it will immediately stop operating and, in some cases, shut down completely . CAUTION: If any SLS equipment safety features fail, your actions may be all that will prevent potentially hazardous operating conditions. Safety Interlocks Safety interlock devices on the SLS equipment help prevent accidental laser exposure, electrical shocks, crush injuries, burns, and fires. SLS equipment will not operate unless all safety interlocks are satisfied. CAUTION: Never try to disable or override any safety interlock device on any SLS equipment. Operating equipment without all safety interlocks enabled can cause equipment damage, injury, or death. If you suspect a safety interlock device is not working properly, do not operate your SLS equipment. Rather, disconnect power from the equipment and contact 3D Systems Customer Support for assistance. a. Internal panels are for service access only. Several interlocked panels are for customer maintenance: overflow cleanout, blackbody cleaning port, and the filter box located on back of machine. Limited Access and Barrier Shielding SLS equipment frame and enclosure designs limit access to the following: • Service areas, such as cabinets and enclosures for electrical power and automation controls. This prevents accidental exposure to electrical shock hazards. • Material areas, such as material feed hoppers, storage bins, and transport tubes. This prevents: • burn hazards by minimizing exposure to heated material • slip hazards by keeping material from dropping on the floor • fire hazards by minimizing airborne dust cloud formation and potential ignition. See SDS for complete material hazard details.
3D Systems, Inc. p/n 77-D005 Rev_A Other Active Safety Features • The ProX® MQC Single Use System, coupled with the Dust Collector, removes airborne material during part breakout in accordance with standard industrial ventilation practices. • An optional room oxygen monitor automatically initiates SLS system shutdown when it detects too little oxygen in the room. • Software in the SLS system automatically initiates immediate equipment shutdown if certain unsafe conditions are detected during operation. ELECTRICAL SAFETY To prevent electrical shock, SLS equipment will not operate unless all external panels are installed and all electrical safety interlock circuits are closed . ELECTRICAL HAZARD: Hazardous voltage exists inside the enclosures of all SLS equipment. Injury or death from electrical shock can result if you remove external panels or try to defeat safety interlocks. Panels should only be removed, and interlocks should only be defeated, by trained and certified 3D Systems Customer Support personnel. ELECTRICAL HAZARD: Verify your facility’s electrical service ratings before connecting
