Form 4 vs. Form 2

Blazing Speed Meets Industrial Production

Form 4 vs. Form 3

Discover how upgrading from Form 2 to Form 4 gives you major gains in speed, throughput, cost efficiency, reliability, and material flexibility.

Improvement

form 4 vs. form 3

Up to 6x Faster Print Speed

Form 4’s Low Force Display™ print engine delivers most prints in under 2 hours, compared to 12–18 hours on Form 2. Print more parts in a day, respond faster to design changes, and boost throughput without adding machines.

“The dramatic increase in print speed for Form 4 has significantly accelerated our fabrication cycle.” 

NASA Goddard Space Flight Center, Matt Mullin, Laser Engineer, Laser and Electro-Optics Branch

45% Larger Build Volume and Taller Parts

Increase productivity by printing more parts in a single build or optimizing orientation for faster print speed.

5× Longer Tank Lifetime

The new Resin Tank for Form 4 lasts over 75,000 layers, minimizing downtime and waste while improving consistency.

50% Lower Resin Cost and access to the Latest Materials

Form 4 uses next-generation resins priced from $79/L, versus $159/L on Form 2. Combined with 5× longer tank life, users cut material costs per part by more than half.

Sharper Details, Smoother Surfaces

Form 4’s 50 μm XY resolution and advanced pixel smoothing deliver injection-molded surface quality with crisp, accurate details. Compared to Form 2’s 140 μm laser spot, parts are cleaner and more precise.

Future-Ready Workflow

Remote monitoring, faster calibration, and built-in diagnostics make Form 4 smarter and easier to maintain.

Compatible with Form Wash and Form Cure, plus a quick-release Flex Build Platform for faster post-processing and light-touch supports that tear away cleanly.

Integrated Camera

Access images and timelapses online to remotely monitor your prints.

Upgraded Cartridge

Our next-generation resin cartridge enables hassle-free, efficient, and fast automatic resin dispensing.

Core Light Source

Form 4 has a backlight Unit with 60 uniform-wavelength LEDs for faster, even layer exposure. While Form 2 has a Laser and galvanometer system (405 nm beam).
