In additive manufacturing, powder residues accumulate constantly throughout the operating process. The valuable powders are subject to the most stringent of quality requirements and should be reused in the printing process. To reduce rejects to an absolute minimum, the powders are processed. 3D printers have an internal or external powder processing unit that uses ultrasound to screen out clumps and other contaminants. The screens are adapted to meet the individual requirements of each powder processing unit.
Powder processing for 3D printing
Screening with ultrasonic technology
Powder processing unit
Several sizes available
- Microscope images of sieved powder and powder with impurities or lumps
- The pictures show the good grains (left) and the screened-out oversize grains (right) in the same resolution/enlargement
- This is metal powder that has been reprocessed after the printing process with Telsonic ultrasonics. During the screening process, a separation efficiency of almost 99% is achieved.
- There is practically no usable powder in the reject powder.
