Stereolithography (SLA) is a 3D printing process used to produce concept models, prototypes, and complex parts with intricate geometries faster, using a wide selection of materials, extremely high feature resolutions, and quality surface finish.

Engineers, designers, and manufacturers choose SLA 3D printing for its fine features, smooth surface finish, ultimate part precision and accuracy, and mechanical attributes like isotropy, water tightness, and material versatility.

However, SL 3D printed parts still require post-processing processes to either strengthen the mechanical properties of the part or to enhance the cosmetics of the design.
