Champ d’application

This standard specifies the safeguarding technical requirements for rapid prototyping machines. It applies to all types of rapid prototyping machines, including those utilizing fused deposition modeling and laser-based technologies. Manufacturers must ensure these safety measures are integrated into the machine design and operation.

Exigences techniques

The standard outlines comprehensive mechanical safety requirements, addressing stability, sharp edges, and moving parts. It mandates the use of interlocking devices for enclosed processing chambers to prevent operation when guards are open. Machine designs must eliminate hazards through inherently safe methods or adequate safeguarding devices. For control systems, the standard requires reliable functionality, fault tolerance, and the inclusion of emergency stop controls. Electrical safety mandates specific protection levels for cabinets (e.g., IP54) and proper insulation and voltage resistance testing. Control system failures must not lead to hazardous situations. It also covers specific hazards related to temperature control, laser radiation, and harmful substances. The standard sets limits on noise emissions and requires proper ventilation for dust and fumes generated during the forming process. Manufacturers must provide comprehensive user information detailing all safety protocols and hazard warnings.

Méthodes d’essai

Compliance is verified through a combination of visual inspections, manual checks, and specific testing procedures. Key tests include electrical safety tests (protection bonding continuity, insulation resistance, and dielectric withstand) conducted according to GB 5226.1. Additionally, harmful substance detection and noise measurement (limited to 70dB(A)) are required to verify environmental and operational safety compliance.
