Solukon Maschinenbau GmbH, Augsburg, Germany, has introduced the SFM-AT1000, an automated powder removal system for de-powdering large additively manufactured parts. The de-powdering process is carried out by programmable pivoting of the components, including the building platform, around two spatial axes.
In order to optimise the powder flow, the powder is ‘fluidised’ with adjustable frequency excitation which enables the cleaning of small openings and channels. Solukon explains that due to the gentle and contamination-free process, the released powder remains unchanged and can be discharged for reuse. The process is fully automated and takes place in a protected atmosphere, thus avoiding contact with health-endangering fine dust and saving valuable working time.
The company states that the SFM-AT1000 is reportedly based on the SFM-AT800 system but features a reinforced slewing system with a novel and particularly compact design. The company states that the aim of the development was to move the higher loads with ease but to keep the chamber volume as small as possible in order to minimise inert gas consumption. The swivel system has two endlessly rotatable servo drives, so that the component can be moved not only exactly into any spatial position.
Solukon’s portfolio currently comprises three machines, the SFM-AT800, which was introduced in 2014 is the largest machine, offering a loading volume of 800 x 400 x 550mm and 300 kg component weight. With the release of the SFM-AT1000, the company introduces two completely new formats, with a component size of up to 460 x 460 x 1,000 mm and 500 x 280 x 1,000 mm.
According to Solukon, its systems meet the highest demands on functionality and are approved for safe processing of reactive and hazardous metal powders thanks to its innovative safety technology. The systems are CE-conform equipped with UL-conform components and built to meet the requirements of NFPA 29.
