Formlabs Grey Resin V4.1 for Form 3 is one of the most popular standard resins in the Formlabs portfolio, delivering a clean neutral grey finish that is the industry standard for prototyping, presentation models, and functional test parts. V4.1 is the latest formulation for the Form 3 and Form 3+ platform, offering improved surface smoothness, consistent colour, and refined mechanical properties compared to earlier Grey Resin versions.

Grey Resin's neutral tone provides excellent contrast for photography, visual inspection, and detail evaluation - making it the reference choice for design review, client presentations, and functional prototypes that need to clearly communicate geometry and surface quality. It is also well suited for paint preparation, as the grey base coat gives consistent adhesion and coverage.
