Formlabs | Grey Pro Resin (Form 3)

$209.00

Grey Pro Resin is a tough, heat-resistant material with low creep, offering greater elongation and improved toughness compared to Formlabs General Purpose Resins. It is a versatile option for concept models, looks-like prototypes, and functional prototypes that require demanding hands-on testing.

Grey Pro Resin is compatible with Form 2 and Form 3 Series printers. Grey Resin V5 on the Form 4 Series offers improved mechanical properties and three times faster print speed, replacing Grey Pro Resin.

IMPORTANT: 5 L Container Requires a Resin Pump to work.
