The SLA process utilizes a UV laser to “draw” a 2 dimensional image in a vat of photopolymer resin. The laser is controlled by the 3D CAD database of your geometry. Wherever the laser contacts with the resin the resin polymerizes (hardens). This is done a layer (.002”-.006”) at a time until the 3 dimensional model is complete. The model is then removed from the machine, rinsed of unpolymerized resin and cured to its final properties under UV lamps. Extraneous rigid support structure and build lines can then be removed from the model. Advantages of SLA are rapid turnaround and complex builds (i.e. undercuts, deep drafts & corners) for larger, detailed geometries.
