SLA – White Resin

White Resin is a 3D printing material designed for Stereolithography (SLA) technology. White Resin is a general-purpose SLA material engineered for precision, surface finish, and visual quality. It delivers an optimal balance of fast print speed, high accuracy, and strong mechanical properties, making it ideal for functional prototypes and presentation-ready models. With a bright matte white finish and the ability to capture fine features, White Resin produces parts that closely resemble injection-molded components. It is designed for reliable, repeatable printing workflows, enabling consistent part quality across both prototyping and production environments. Built on the latest Formlabs platform, White Resin offers significantly faster print speeds compared to previous generations while maintaining excellent dimensional accuracy and surface detail.

Key Material Facts:

• General-purpose SLA material optimized for high accuracy, surface quality, and reliable performance.
• Bright matte white finish produces parts that closely resemble injection-molded components, ideal for presentation and visual prototypes.
• Captures fine features and intricate details with excellent dimensional accuracy.
• Balanced mechanical properties provide strong, stiff parts suitable for functional prototypes, jigs, and fixtures.
• Fast, reliable printing workflow designed for consistent results across prototyping and production use.
• Parts can be printed solid and air / fluid tight right off the printer, no sealing required.
• Compatible with assembly features including:
  • Glue Joints / light welding
  • Printed In Threads (However Helicoils are recommended)

Common Applications:

• Form and fit prototypes for evaluating geometry, assemblies, and part fitment
• Presentation-ready models with high surface quality for customer reviews and product demos
• Concept models and visual prototypes that require fine detail and clean aesthetics
• Jigs and fixtures where dimensional accuracy and stiffness are critical
