Issues of ensuring occupational safety when using contemporary additive technologies, particularly 3D FDM printing to manufacture casting forms and stems from composition materials based on wax and fillers have been considered. The features of such materials as WAX3D, issues of working space planning, casting procedures, and the use of tooling have been studied. The main types of employee health and safety risks occurring during the operation of industrial equipment, storage and processing of materials, as well as post-printing processing, have been studied. The stages of experimental studies aiming to identify potential hazards of 3D printer operation and during casting production, including the preparation of samples of various filling density, choice and use of personal protection equipment, as well as the workflow management in specially equipped premises with modern ventilation systems, are described.
Special attention has been paid to the issues of professional risk mitigation due to regular informing and training of personnel, developing first aid regulations, and equipping workplaces with emergency shutdown buttons and microclimate monitoring systems. The article provides experimental data on the absorption, strength, and deformation of WAX3D material samples printed with various filling densities. The results obtained have been analyzed, and practical recommendations on ensuring occupational safety in conditions of mass 3D technology implementation in casting production have been given.
Regulatory requirements for the arrangement of the production environment for additive technologies have been reviewed. The production process optimization methods, considering the specifics of materials and equipment in use, have been revised. The study can be useful for engineering personnel of casting and machine-building enterprises, and managers of departments implementing modern technological processes in industrial production.
