Formlabs Clear Resin V4.1 for Form 3 is the latest formulation of Formlabs' transparent SLA resin for the Form 3 and Form 3+ platform. Version 4.1 delivers improved optical clarity, better surface finish, and refined mechanical properties compared to earlier Clear Resin formulations, making it the material of choice for parts where transparency, light transmission, or a glass-like appearance are required alongside the high dimensional accuracy of SLA printing.

Clear Resin is widely used across industries for fluid-containing parts and fixtures, light guides and lens prototypes, display covers and visual inspection windows, microfluidic devices, and any application where visibility through the part is functionally or aesthetically important. Post-sanding and polishing can further enhance clarity to near-optical transparency for demanding display applications.

Key features

• V4.1 formulation delivers improved optical clarity and surface quality compared to earlier Clear Resin versions on Form 3 hardware.
• High transparency enables use for light guides, lens prototypes, display covers, fluid fixtures, and visual inspection components.
• Excellent dimensional accuracy and smooth surface finish from SLA printing, suitable for precision optical and visual applications.
• 1-litre cartridge integrates with the Form 3 automated resin system for clean, consistent material handling without manual mixing.
• Can be post-processed by wet sanding and polishing to achieve near-optical transparency for display-quality parts.
• Also available as Grey Resin V4.1 for Form 3 for a neutral-coloured alternative on the same platform.

Compatible with: Formlabs Form 3, Form 3+
