ABSTRACT: Among the many Layered Manufacturing (LM) processes, the poly-jet 3D printing system uses
drop on demand ink-jet technology to produce prototype as well as the functional components in polymers.
The functional performance and aesthetic appearance of these LM parts is affected by the surface roughness.
Process parameters such as layer thickness, ...
