MECHANICAL DATA

Please note that all mechanical properties reported here have been tested on material in the as-deposited conditions, i.e. without hot isostatic pressing or any other heat treatment applied to the material. The only exception is that of aluminium, in which case the effect of the T6 temper was also evaluated.

The following figure explains the meaning of the single, parallel and oscillation deposition strategies, which are adopted to produce parts of whatever thickness is required.

Comparison of different deposition strategies and wire cost

WAAM delivers static properties that comply with the AMS standard for wrought products, in the as-deposited conditions.

 

 

 

With the inclusion of high-pressure rolling:

The addition of rolling to WAAM produces properties that are better than the wrought alloy.

 

 

 

Comparison with other processes

WAAM beats other high-deposition rate processes.
