...) is primarily constrained by the diameter of the jetted droplet, which is typically in the range of 40 to 60 μm. The resolution in the z -plane (i.e., the layer thickness) is even higher because the jetted layer can be compressed by a rolling mechanism (e.g., as small as 13 μm in 3D Systems’ machines...
