Performance improvements of vapor-smoothed SLS PA2200 parts

A study with Hansgrohe applied AMT vapor smoothing to SLS PA2200 parts to improve their quality and performance, measuring strength, surface roughness, dimensions and burst pressure.

Mechanical strength

Vapor smoothing increased tensile strength and elongation at break, improving the durability of the printed components.

Surface quality

Surface roughness fell by up to 71% across different orientations, a high-quality finish without manual work.

Precision

Dimensional variation after post-processing was very low, a maximum change of 0.4%, well within the tolerances expected from standard 3D printing processes.

Watertightness

Average bursting pressure rose by up to 7%, improving watertightness and part longevity.
