Powder Supply Unit (PSV) Fully automated powder supply using vacuum technology

Conveying Routes of PSV 1. Conveying route – Feed The freshly sieved metal powder is supplied into the SLM machine. An ultrasonic sieve, which is integrated in the PSV, sieves the available powder just before it is fed into the process so that no oversized particles or foreign objects can find their way into the SLM process. 2. Conveying route – Recirculation The second conveying route returns the excess metal powder from the conversion shafts back to the PSV. 3. Conveying route – Recovery Unpacking of built parts and recovery of the unfused powder is done inside the process chamber of the SLM...

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...
