Premieres set for Formnext 2021

Surface finishing for AM neophytes

At Formnext 2021, Walther Trowal will be on hand to present the Trogvibrator TRT 83/87, which is designed for use in post-processing the surfaces of 3D-printed components. It is capable of producing smooth, polished surfaces by means of vibratory finishing, especially when small batch sizes are involved.

The vibration of the trough produces relative motion between the workpiece and the rotary vibrators, which in turn results in a smooth, consistent surface.  Picture: Walther Trowal

Walther Trowal has developed its vibratory finishing machines specifically for AM workpieces. They are fine-tuned to handle the coarse surfaces often seen in Additive Manufacturing – the “staircasing” effect, marks left behind by support structures, and baked-on powder residue, for example.

In the Trogvibrator TRT 83/87, the workpiece at hand is inserted into the rotary vibrator bed. The vibration of the trough produces relative motion between the workpiece and the rotary vibrators, which in turn results in a smooth, consistent surface. Christoph Cruse, director of sales at Walther Trowal, describes the TRT 83/87 as a machine suitable for those just getting started in AM.
