SLA (Stereolithography) 3D printing is an additive manufacturing technology that works by curing liquid resin layer by layer using an ultraviolet (UV) light source. Here's a breakdown of how the process generally works:
Preparation: The 3D model is prepared using computer-aided design (CAD) software and sliced into thin layers.
Printing: The liquid resin is contained in a vat or reservoir. A platform is submerged into the resin, and a UV laser or projector selectively cures the resin according to the sliced layers of the model. Wherever the UV light hits the resin, it solidifies into the desired shape. The platform then moves incrementally upward, and the process repeats, layer by layer, until the entire obje...

Printing: The liquid resin is contained in a vat or reservoir. A platform is submerged into the resin, and a UV laser or projector selectively cures the resin according to the sliced layers of the model. Wherever the UV light hits the resin, it solidifies into the desired shape. The platform then moves incrementally upward, and the process repeats, layer by layer, until the entire object is printed.
Curing: After each layer is exposed to UV light and solidified, the platform moves up slightly to expose fresh resin for the next layer. The process continues until the entire object is printed.
Rinsing: Once the printing is complete, the object is removed from the printer. It's typically rinsed in a solvent to remove any excess or uncured resin from its surface.
Post-curing (optional): Some SLA printed objects may require additional UV curing to further harden the resin and improve its mechanical properties.
SLA printing offers high-resolution prints with fine details, making it suitable for applications like prototyping, jewelry making, dental modeling, and intricate miniatures. However, it can be slower compared to other 3D printing methods, and the resin materials can be more expensive.
