Powder feeding unit PSV

for printing machinesautomatic

The various functions of the powder supply unit PSV ensure secure powder supply without the need to manually refill the powder during the build process. The PSV, equipped with a 90l powder tank, supplies the SLM® machine with freshly-sieved metal powder as required. Excess metal powder from the build process is automatically returned to the PSV powder supply tank. No manual intervention is required. After the production process, a manually guided extraction unit returns metal powder that has not been used to the PSV. The powder is transported by vacuum technology with three conveying routes. Conveying routes exist to supply and return the powder during the production process, and to recover the powder after the production process. These can be activated as required. Powder transport, powder sieving and the storage of the powder in the PSV tank take place in a closed system with constant inert gas atmosphere. Contactless powder handling ensures maximum safety at work. In addition to supplying the powder, the PSV measures the available powder amount and displays this in the Machine Control Software (MCS). Powder components that cannot be reused are separated out into a special container by the sieving unit. It is possible to connect a powder container with a DN40 connector to the main tank of the PSV, to supply new metal powder. Alternatively the powder container can be emptied inside the PRS 500 or the process chamber of an SLM®280 via a suction device.
