Additive production processes already have many uses when it comes to manufacturing prototypes, mock-up and exhibition models and spare parts in very small series. As product development and time-to-market periods keep getting shorter, 3D printing is also increasingly becoming a major component in the area of rapid manufacturing. One specific method used in additive production is selective laser melting (SLM). This involves fine layers of metal powder being applied to the powder bed and melted by lasers. This process is carried out in a protective gas atmosphere as the laser smoke particles that are created are highly charged and reactive. They must not under any circumstances come into contact with oxygen as this would pose a fire hazard.
The gas filtration has to meet very high requirements in order to remove these particles. As a filter specialist, HYDAC has decided to tackle this exceptional challenge and has developed an innovative filter system: the FlushPACK.
