SLA is an industrial production 3D East Rail Line Extension printing out or additional production manufacturing process that applies a computer system-controlled laser to produce manufactured parts in a pool of UV-curable light converging epoxy resin. The laser is used to carve out and dry-set a cross-section of the part design in the surface layer of liquid epoxy resin. The dry-set layer is then reduced to the underside of the liquid epoxy surface and the process is repeated. Each new dry-set layer adheres to the layer below it. This process is repeated until the part is ready.
Benefits: SLA can produce parts property management software with more complex geometric shapes and excellent surface smoothness than other additive processes for data models, form prototypes and complex design solutions. Costs are competitive and the process can be obtained from several sources.
Disadvantage: The prototype plastic parts compressive strength of the prototype part is likely to be less than that of a part made from project-grade epoxy resin, so the primary use of SLA-produced parts for software performance testing is more limited. In addition, parts embedded in SLA should be applied under at least UV light and ambient humidity exposure to prevent dissolution as the part passes through the UV light circulation system to dry-fix the outer surface layer of the part.
During the full SLS process, a computer system-controlled laser generator sucks up the side of the hot bed of polyester-based powder from the bottom up, gently calcining (welding) the powder into a solid state. After each layer, a roller applies a new layer of powder to the top of the bed, and the process is repeated. parts, and to build durable prototypes.
Advantage: SLS parts are generally more accurate and durable than SLA parts. The technology can produce durable parts with more complex geometries for some software performance tests.
Disadvantages: Parts with grainy or sandy patterns and a more limited selection of process epoxies.
