Figure 5.1: SLA printing process
Once a layer is created, the platform is raised, and model is taken out of
the resin. After creating every layer, the 3D model needs to be taken out
of resin for delaminating and recoating. Then it must be repositioned into
the resin for creation of the next layer. So, the platform is again lowered to
a depth that all layers built till then are immersed into the resin and resin for
next layer creation is available for UV exposure. This way each layer is
created and after finishing final layer the platform is finally raised out of the
liquid resin and allowed to cool.
