Accura 25 overview

Accura 25 is a high-performance stereolithography resin that combines the precision of industrial SLA with ABS-like mechanical properties. Unlike desktop SLA resins, Accura 25 delivers exceptional dimensional accuracy, smooth surface finish, and reliable mechanical performance across large build volumes up to 1500 × 750 × 550 mm. Its balanced properties make it ideal for functional prototypes, master patterns, and detailed concept models where both aesthetics and functionality are critical.

Why manufacture with Accura 25

Accura 25 combines exceptional surface finish and detail resolution and abs-like mechanical properties with good impact resistance, delivering large build volume capability up to 1500mm for demanding applications. From rapid prototyping to production runs, teams rely on Accura 25 to maintain tight tolerances while reducing assembly complexity through consolidated part designs. Accura 25 bridges the gap between appearance models and functional prototypes, eliminating the traditional trade-off between aesthetics and performance. Our ProX 800 systems achieve layer resolutions down to 50 microns with sidewall quality that rivals injection molding, while the material's 10-20% elongation enables functional features that survive real-world testing. This unique combination makes Accura 25 the fastest path from concept to validated design, with parts ready for painting, plating, or clear coating straight from post-processing.

SLA Production Technology

Accura 25 leverages 3D Systems ProX non-inverted SLA architecture to deliver ABS-like properties with unprecedented precision and surface finish. The right-side-up vat photopolymerization eliminates gravitational stress and peeling forces that plague inverted systems, enabling 0.1mm support touchpoints that leave virtually no marks—critical for master patterns and presentation models. With 3D Sprint's automated support optimization achieving 44% higher build density than desktop SLA, Accura 25 produces functional prototypes 5.1x faster per part. The material's 38-41 MPa tensile strength and 10-20% elongation combined with minimal post-processing (2.9 minutes vs 8.9 minutes for inverted systems) make it ideal for snap-fit assemblies and production tooling.
