94.What is Stereo Lithography Apparatus(SLA)?
SLA rapid prototyping is the oldest and most common technology. It involves a laser beam moving through a vat of ultraviolet-sensitive liquid polymer which follows the contour of the digital 3D model. The beam strikes on a layer of ultraviolet-sensitive liquid polymer, and then the thin layer is solidified. The laser will keep repeating the same process from the bottom to the top of the 3D model. A temporary framing support for the model is required, because the process is from the bottom up. Stereo Lithography machines are manufactured by 3D Systems Inc. The final model usually requires a little bit of sanding, and it is inappropriate for an office setting because this process produces toxic fumes. SLA is simple, fast and accurate.
