Formlabs Grey Resin V4 is the standard grey photopolymer resin for the Form 3 SLA 3D printer, available in the large 5-litre cartridge for high-volume production environments. Grey Resin V4 is the benchmark formulation for general-purpose SLA printing on the Form 3 series, offering excellent surface finish, fine feature resolution, and reliable layer-to-layer consistency across a wide range of part geometries. The neutral grey colour makes surface details highly visible, making it the preferred choice for quality inspection, fit checks, and visual prototyping.

The 5-litre cartridge format is designed for professional studios and production teams that print frequently and need to minimise cartridge swap downtime. Grey Resin V4 is optimised for the Low Force Stereolithography (LFS) print engine of the Form 3, ensuring consistent resin delivery and accurate part reproduction across the full build volume. It is well-suited to product design verification, concept models, and general engineering prototypes where dimensional accuracy and surface quality are paramount.
