Metal 3D Printer Dust Collection System

Product Description

The SAYKAR Dust Recycling Machine is an ATEX II ex D certified, Ex-proof machine designed for recycling the metal dust released during the manufacturing of products made with three-dimensional printers. The operator selects the dust collection mode on the HMI touchscreen and starts the vacuum pump; the metal dust drawn in through the vacuum nozzle is first collected in the 316L stainless steel cyclone unit.

The weight of the dust accumulated in the cyclone is tracked in real time with a load cell, while maximum fill level is monitored with an upper-level sensor. Once collection is complete, the system switches to sieving mode: first, the oxygen in the environment is reduced to the target level (2-5%) with argon inert gas, then the pinch valve under the cyclone opens and the dust is transferred to the vibrating sieve. The sieve, mounted at a 10° angle, performs efficient sieving without clogging through the combined action of mechanical vibration and an ultrasonic vibration probe — it can be changed according to the desired mesh size.

The sieved dust, ready for reuse (max. 80 µm), is transferred to the 316L stainless steel storage tank, while larger particles that cannot pass through the sieve are transferred to a separate waste tank; the weight of both tanks is measured in real time with a load cell. The system has two-stage filtration to prevent dust from entering the vacuum pump: 4 pieces of 1-micron ATEX certified cartridge filters inside the cyclone (automatically cleaned by the Jet-Pulse system) followed by a HEPA filter. All hose, bellows and clamp connections are Ex-proof/ATEX certified and grounded.
