Formlabs Form 4
Blazing Speed Meets Industrial Production
The Formlabs Form 4 is a next-generation SLA 3D printer that delivers industrial reliability with up to 5× faster print speeds, completing most jobs in under two hours. Built with the proprietary Low Force Display™ (LFD) print engine, it offers a 98.7% success rate and supports a wide range of high-performance materials. Designed for engineering, manufacturing, and dental labs, it enables intuitive, automated workflows for both rapid prototyping and end-use production.
Key Features of Form 4
Blazing Speed
Prints full builds in under 2 hours, with vertical speeds up to 100 mm/hr.
Unmatched Productivity
Delivers up to 3× faster throughput than previous generations, with peak efficiency of 1 minute per part.
High Accuracy
Ensures ±0.15% XY tolerances for precise assemblies that fit every time.
Sharp Details
50 µm pixel size, highly collimated light, and anti-aliasing deliver subpixel resolution and crisp features.
Smooth Surfaces
Low peel forces and light-touch support provide injection-molded quality finishes.
Material Versatility
Compatible with Formlabs’ full resin library—high-temp, tough, FR, and ESD-safe—as well as third-party resins via Open Material Mode.
Intuitive Workflow
Features automatic resin dispensing, quick-swap tanks, and a hassle-free cartridge system for seamless operation.
Low Force Display™ (LFD) Technology
Enables reliable curing, faster cycles, and consistently high success rates.
