Big Parts, Blazing Fast
Large prints in under 6 hours, 4.6x larger build volume than Form 4.
BLAZING SPEED MEETS INDUSTRIAL PRODUCTION
Get More Done with most Prints in under 2 hours.

TACKLE ANY PROBLEM
WITH OUR INDUSTRY-LEADING RESINS AND OPEN PLATFORM.
Leverage high-performance materials
optimized for impact resistance, rigidity,
flame retardancy, flexibility, and more.
Non-acrylate chemistries like true silicone,
ceramic, and polyurethane materials.
Certified third-party materials and open
mode available.
Option to customize print performance for
your exact part using editable and
shareable print settings.

STUNNING PARTS
THAT ALWAYS FIT WITH A SURFACE FINISH THAT RIVALS INJECTION MOLDING.
Sharpest details: highly collimated light with
pre-tuned anti-aliasing for subpixel resolution.
Smoothest surfaces: lower peel forces and
light touch supports.
Most accurate assemblies:
±0.15% XY dimensional tolerances so
assemblies always fit.

UNMATCHED RELIABILITY
STOP COMING BACK TO FAILED PRINTS.
Validated Print Settings
Intelligent Control Systems
Re-Engineered, Long-Lasting Consumables
