Precision Prototyping

High-Detail Precision Prototypes

Essential for product development teams requiring exceptional surface finish and dimensional accuracy, SLA excels in detailed concept models, master patterns, and functional prototypes. The photopolymer curing process delivers smooth surfaces with minimal layer lines, making it ideal for visual prototypes, casting patterns, and intricate architectural models. With sub-millimeter precision and excellent feature resolution, SLA bridges the gap between initial design concepts and production-ready parts.

Production applications

Precision Design Validation

Design teams leverage SLA for rapid iteration cycles, with parts ready for testing within hours of design completion. The liquid photopolymer process enables wall thicknesses as thin as 0.6mm and feature details down to 0.1mm, perfect for capturing intricate textures, fine text, and complex internal structures. Post-processing techniques like sanding, painting, and metal plating transform prototypes into presentation-ready models indistinguishable from final products.

Key advantages

Complex geometries: Intricate internal channels, overhangs, and assemblies impossible with traditional manufacturing.

Functional prototypes: Test mechanical properties and fit before investing in production tooling.

Custom tooling: Jigs, fixtures, and manufacturing aids tailored to specific production requirements.

End-use parts: Production components for aerospace, medical, automotive, and industrial applications.

Industry Applications

SLA Applications Across Industries

Stereolithography (SLA) is the go-to when surface finish and dimensional accuracy matter as much as speed. Teams use SLA for paint-ready appearance models, tight-tolerance assemblies, and clear or transparent parts used for fit checks, optics, and flow visualization.

SLA excels when you need crisp features, smooth surfaces, and repeatable tolerances before committing to tooling or higher-volume production. It is commonly selected for presentation models, validation builds, and low-volume components where visual quality is part of the requirement.
