Stereolithography

SLA rapid prototyping (stereolithography) is an additive manufacturing process that uses ultraviolet light to cure liquid resin layer by layer, creating highly detailed prototypes with smooth surface finishes and excellent accuracy.

SLA prototyping provides excellent detail resolution, smooth surface quality, and accurate reproduction of complex geometries. It is ideal for creating visual prototypes, concept models, and functional testing parts during product development.

SLA is commonly used for concept models, product design validation, functional prototypes, master patterns, and appearance models where high detail and surface quality are required.

SLA uses specialised photopolymer resins designed for different prototype requirements, including rigid, flexible, and transparent applications. Material selection depends on factors such as strength, appearance, flexibility, and testing requirements.

Yes. SLA prototypes can be used for functional testing, fit checks, and design validation. The suitable resin and finishing options depend on the performance requirements of the application.

SLA uses liquid resin cured with ultraviolet light to create highly detailed parts with smooth surfaces, while SLS uses powder-based materials to produce durable parts with greater design freedom for certain applications. The suitable process depends on the required accuracy, material properties, and prototype requirements.

SLA is ideal for complex geometries, detailed models, and prototypes requiring smooth surface finishes. CNC machining is better suited for prototypes requiring production-grade materials, high strength, and precise mechanical performance.

SLA is one of the most accurate 3D printing technologies available, making it suitable for prototypes requiring fine details, tight features, and precise design validation.

Yes. SLA prototypes can be post-processed with finishing options such as sanding, painting, polishing, and other surface treatments to achieve the desired appearance and functional requirements.

Lead time depends on factors including part size, design complexity, material selection, and finishing requirements. SLA is widely used for rapid prototyping because it enables faster production of detailed prototypes compared with traditional manufacturing methods.
