Photopolymer is cured and hardened by scanning laser beam to make a layer. The process continues layerwise until the full product is fabricated. This is an older process than SLS and was preferentially used for RP and RT before the advent of SLS. For making bigger prototypes, it is still preferred (158,159).
The second variable that you should check when using wall functions is the wall liftoff (in length units). This variable is related to the assumed thickness of the viscous layer and should be small relative to the surrounding dimensions of the geometry. If it is not, then you should refine the mesh in these regions as well.

An actively controlled, pneumatically-actuated constant force device (CFD) which may be fixed to a stationary mount or moved in three-dimensional space proximate a work surface. The device applies substantially constant force from an actuator, through a linkage, to a tool in contact with a work surface, e.g., a drilling, grinding or finishing tool, or a laminating roller.
discrete variables In a CFD solution, one would directly solve for the relevant flow variables only at the grid points. The values at other locations are determined by interpolating the values at the grid points. The governing partial differential equations and boundary conditions are defined in terms of the continuous variables p, V~ etc ...
