Overview
Form 4 is a fast masked SLA (MSLA) 3D printer that pairs a broad materials library with a precision print engine. It is designed for professional prototyping and low-volume production workflows, providing rapid cycle times, consistent part accuracy and integrated software tools.

Key benefits

• FAST: Most prints complete in under 2 hours (80th percentile at 53 mm height, 100 µm layer thickness).
• MATERIALS FLEXIBILITY: Supports 23 Formlabs materials and compatible 405 nm third‑party resins via Open Material Mode.
• SIMPLE WORKFLOW: PreForm and Dashboard streamline print preparation and remote monitoring; typical operator onboarding ≈15 minutes.
• REPEATABLE RESULTS: High success rates for professional workflows and predictable dimensional accuracy.
• INTEGRATED MONITORING: Built-in 5 MP camera for timelapses, print history and remote checks (can be disabled or removed).

Summary description
The Form 4 uses Low Force Display (LFD) technology — a backlight unit with high-power LEDs and collimating optics to cure resin quickly and uniformly across the build platform. The system is compatible with a wide range of engineering, elastomeric, castable and specialty resins and integrates with PreForm and Dashboard for preparation and fleet management.
