SLA, like any other additive manufacturing process, creates a model in a layered approach. It uses liquid plastic or curable photopolymer to serve as the material for each layer. The ultraviolet laser draws the object onto the liquid surface layer by layer until all layers are completed. When a layer is finished, it is exposed to ultraviolet laser light that solidifies the layer and allows it to merge with the previous layer.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>What Does Stereolithography Mean?
