Gas-tight blowers for additive manufacturing methods

In selective laser melting (SLM) a stable inert gas atmosphere must be ensured within the built chamber of the machine. A specified temperature range is also essential. Only under these conditions can high quality components be produced. It is further necessary to remove metal splash and smoke developing during the melting process.

At formnext (hall 3.0, stand H 69) Gebr. Becker GmbH will be presenting two blower types developed precisely for these and similar applications. The key difference to other series is the gas-tight design which permits the precise control of the gas flow as well as the removal of contamination from the process. In combination with also gas-tight heat exchangers from the programme of Gebr. Becker they also create the conditions for an exact temperature control of the additive manufacturing process.

For plants with a small built chamber the gas-tight and speedcontrolled VASF side channel blowers of size 1.50 are ideal (figure 1). They are of a highly compact construction and can be easily integrated in the plants, enabling the flow management of the inert gas in the closed circuit and low energy operation as required.

For larger plants in additive manufacturing and the correspondingly higher volume flows of inert gas the gas-tight side channel blower VARIAIR SV 300 is used (fig-ure 2).Here too, the speedcontrolled energyefficient drive enables the delivery rate to be adapted to the actual requirements.

Both blowers are designed for 24/7 industrial operation and proven worldwide in numerous demanding applications. Due to their gas-tight design they are suitable for the requirements of additive manufacturing in highgrade atmospheres.
