Formlabs Clear Resin V4.1 (Form 3) - 1L - Add Labs is a premium stereolithography material engineered for applications requiring high optical transparency and a polished surface finish. This updated v4.1 formulation is specifically tuned for the Form 3 series printers, offering improved print reliability and clarity compared to previous iterations. Consequently, it remains the primary choice for engineers and designers creating transparent prototypes, millifluidic devices, and complex internal geometries that require visual inspection.

Optical Clarity and Precision with Formlabs Clear Resin V4.1 (Form 3) - 1L - Add Labs
This resin excels at producing parts with a smooth surface finish that can be post-processed to near-optical transparency. Furthermore, its mechanical properties allow for the creation of rigid, stable components that maintain their dimensional integrity over time. Users can customise the level of transparency through various sanding and polishing techniques or by applying a clear coat to the printed surface. This versatility is essential for lighting prototypes, lenses, and any application where light transmission is a critical requirement.


The integration with the Form 3 platform ensures a seamless workflow via the automated resin dispensing system. Each 1-litre cartridge is monitored by the printer to prevent mid-print failures due to material depletion. Whilst the material is rigid, it offers enough tensile strength to support functional assemblies. By utilising Formlabs Clear Resin V4.1 (Form 3) - 1L - Add Labs, professionals ensure their projects benefit from the highest standards of translucency and detail currently available in professional desktop 3D printing.
