The morQ is a new generation test specimen developed to assess and optimize the AM value chain with a specific emphasis on surface quality and geometrical accuracy.
Think #3DBenchy for powder bed fusion.
The test specimen contains a variety of flat surfaces with different build orientations and a wide range of geometries to form a challenging part to print and post-process. Additional features can be added to support specific application needs. The morQ functions to test the boundaries of AM and post-processing including the application of coatings. Engineers can employ this specimen to optimize processes for component performance.
For the verification of surface quality it is important for the morQ to contain complex geometrical shapes that present difficult to reach positions, undercuts, inside and outside surfaces. This presents a challenge for the AM process and any finishing process that may be necessary and coating process. Below, there is information on all surface geometries, labelled according to the naming conventions explained on the previous tab.
