Understanding the Magic Behind SLA Printing
SLA printing utilizes a laser beam to solidify liquid resin layer by layer, meticulously building your desired 3D object. Unlike other 3D printing methods like FDM printing (Fused Deposition Modeling) that use filament, SLA printing works with photopolymers - light-curable resins. During the printing process, the laser selectively cures the resin on the build platform, creating a solid layer that corresponds to a single slice of your 3D model. This process repeats itself, progressively adding cured resin layers until the entire object is complete.
This layer-by-layer approach, paired with the precise nature of laser technology, allows SLA printing to achieve incredibly fine details and smooth surface finishes. The resulting objects are known for their dimensional accuracy and high resolution, making them ideal for applications where intricate details are paramount.
