Powder screening station: for fine plastic powders

No precise additive manufacturing processes are possible without powder screening stations: When it comes to reliable 3D printing, the quality of the plastic powder is crucial. Above all, oversized particles or foreign matter have negative effects on the printing process. Differing particle sizes occur naturally, especially with reused powders. The screening station developed by IB Additive ensures that the plastic powder needed for a print job is harmonised in terms of particle size, both for new powders and for reused materials.

Facts that will convince you

  • Designed for new and used powders
  • Easy to clean, can be used autonomously and integrated
  • Quiet and compact
  • Achieves high throughput and long service life with its ultrasonic drive

Product description

The material for 3D printing is fed manually or by pump into the screening station, which separates the oversized from the correctly sized particles with a screen fabric that has been specially developed for plastic powders. Particles remaining on the fabric are collected in the oversized particle container for disposal. The screening station can be used independently and can be moved by means of locking rollers. The solutions from IB Additive are of compact design, have an interface to the conveyor line and can be easily integrated into the existing flow of materials. Alternatively, the correctly sized fraction can be collected in a correct-size container and fed manually into the printing process.
