Additive Manufacturing:
3D Printing
Most large scale Additive Manufacturing, or 3D Printing, processes use powders.
-
Moisture in the powder can cause it to become sticky affecting its flowability. This puts the consistency of a laser build process at risk.
-
Moisture in the powder during a laser build impacts on porosity and densification of the final material reducing its strength and quality.
Powders used for Additive Manufacturing should contain no moisture.
Relequa® Moisture Profiling™ is used to determine the Water Vapour Equilibrium Point (WVEP) of the dry powder. The WVEP is set as the Starting %RH in our new test that measures moisture status in just 2 minutes.
The graph shows the initial Relative Humidity (%RH) of 45% increases within the test chamber as a result of the powder releasing moisture. The increase in %RH caused the test to run past the expected 2 minute mark for a dry powder, continuing until the new moisture status of the sample was measured.
Relequa’s 2 minute test for moisture status answers these two vital questions:
Does the powder contain moisture?
When is the powder dry?
