Standardisation: risk assessment related to additive manufacturing

A new standard is currently being developed for assessing the risks but also for setting up measures of prevention and protection relative to the processes of additive manufacturing with metallic materials. This document also includes a part dedicated to waste management. It is drafted jointly by the ISO/TC 261 and ASTM F42 technical committees for additive manufacturing.

The objective is to help companies to define methods for risk assessment according to the materials used, the processes, conditions of installation of the machine, good engineering practice and actual feedback. This is based on a characterisation of the physical risks (fire, explosion), risks for the health of the operators and other people exposed, and risks for the environment.

Like corrective and preventive actions, these methods consist in analysing the entire process and assessing the risks at each level from probability, frequency and effect viewpoints. For each risk or hazard found, preventive organisational measures have to be proposed and their effectiveness has to be measured and monitored. This document is quite recent (Committee Draft), but already gives the main directions for a step-by-step assessment of the different hazards related to the chemical products, the powders, the substances generated by the process itself and to the risks of fire or explosion. It also gives general information about prevention and protection measures, and about treating the waste produced.
