This is not true of some alternative powder processes, such as hot isostatic pressing, that can manufacture parts with superior mechanical properties.

Biofabrication: A Guide to Technology and Terminology:

This technology allows the fabrication of structures with a lateral resolution controlled by a combination of the powder particle size and the volume that the solvent penetrates by capillary action. Current commercial systems have a feature resolution around 300 μm, which is suboptimal if precise control of cell positioning is required after scaffold fabrication.
