Overview
Fast Model Resin is Formlabs' fastest SLA resin optimized for Form 4 Series printers, enabling rapid prototyping and large-format prints with reduced cycle time while maintaining improved mechanical performance compared with previous draft resins.

Key features

• Extreme print speed: >100 mm/h on Form 4 and >80 mm/h on Form 4L, allowing full Form 4 builds in under two hours and full Form 4L builds in under five hours.
• Improved mechanical properties vs Draft Resin V2 — up to ~45% higher tensile strength and stiffness.
• Matte grey, presentation-ready appearance with smooth surface finish.
• Ultra-low odor formulation (very low VOCs) for a better working environment.
• Fast post-processing workflow: example guidance cites a 5‑minute wash and 5‑minute room-temperature post-cure for quick turnaround.
• Compatible with standard and Flex build platforms and respective resin tanks for the Form 4 Series.

Additional product notes

• Print technology: SLA.
• Color: matte grey.
• Categories: General Purpose, Dental.
• Fast post-processing recommended: short wash then short post-cure to reduce surface tack and improve mechanical properties; Formlabs guidance references short wash and short cure workflows for fast turnaround.
• Designed for high-throughput prototypes, rapid design iteration, and large models that require quick turnaround.
