Abstract
A filter assembly for an additive manufacturing apparatus has a housing defining a gas inlet and a gas outlet. A filter element is located within the housing between the gas inlet and the gas outlet. The assembly includes valves that can be actuated to seal the gas inlet and the gas outlet. Additionally the assembly has a fluid inlet for allowing ingress of a fluid into the housing. The assembly allows a filter element, which may contain volatile particles, to be changed safely. By sealing the gas inlet and outlet and flooding the housing with a suitable fluid, volatile particles captured by the filter can be neutralised.
