Printing and Post-Processing Behavior

Grey V4 is delivered in a cartridge, with automatic selection of print parameters on compatible Formlabs SLA printers. Its formulation is optimized for the Low Force Stereolithography (LFS) process of the Form 3 series and provides high dimensional accuracy, an opaque matte finish, and a superior surface finish compared to FDM ABS parts after post-processing.

Formlabs standard resins do not require strict post-curing, but a Form Wash cycle (isopropyl alcohol) followed by a Form Cure is recommended to achieve maximum mechanical properties and a non-tacky finish. For the Form 4 series, Grey V5 (improved speed and mechanical properties) supersedes this reference.

Applications

The Standard range targets general prototyping, models with very small details, presentation models, bases for painted parts, and visual validation parts. The neutral tint facilitates painting and finishing operations. Once post-processed, the parts exhibit superior tensile strength and stiffness compared to injected or FDM ABS printed parts, making it a versatile consumable for high-resolution prototyping.
