Formlabs Form 4 Basic Package – Professional SLA 3D Printer

Bring professional resin 3D printing in-house with the Formlabs Form 4, a fast, accurate, and reliable professional SLA 3D printer designed for engineering, product development, manufacturing, research, education, and production applications.

Form 4 combines Formlabs' Low Force Display™ (LFD) print engine with a powerful materials ecosystem and streamlined workflow. Its masked stereolithography technology cures an entire layer at once, enabling fast print speeds that remain largely independent of how many parts are placed on the build platform.

With a 200 × 125 × 210 mm build volume, 50 μm pixel size, and print speeds of up to 100 mm per hour, Form 4 makes it possible to move quickly from CAD model to high-quality physical part without sacrificing dimensional accuracy or surface finish.

The Form 4 Basic Package includes the essential hardware needed to begin building a professional Formlabs SLA workflow. Resin and washing/curing equipment are sold separately.

Why Choose the Formlabs Form 4?

Fast Professional SLA Printing

Form 4 is designed to dramatically reduce the time between design and finished part. Most typical Form 4 prints can be completed in under two hours, while maximum print speeds can reach 100 mm per hour with compatible materials and settings.

Because each layer is exposed simultaneously, adding more parts to the build platform has little impact on print time compared with traditional laser-based SLA systems.

For product development teams and production environments, that means more design iterations, more parts per day, and shorter turnaround times.

Low Force Display™ Technology

At the heart of Form 4 is Formlabs' Low Force Display™ (LFD) print engine.

The system combines:

• High-power LED backlight
• Light Processing Unit 4 (LPU 4)
• Flexible-film resin tank
• Release texture
• Intelligent control systems
• High-speed automatic resin handling

A 405 nm backlight using 60 LEDs produces uniform illumination across the build area, while the LPU precisely defines each layer of the model.

The result is a resin printing platform designed for speed, consistent dimensional accuracy, fine detail, and repeatable production.

Accurate Parts and Fine Detail

Form 4 uses a 50 μm pixel size with pre-tuned anti-aliasing to produce crisp features and smooth surfaces.

Typical XY dimensional tolerances are:

• 1–30 mm features: ±0.15%, with a lower limit of ±0.02 mm
• 31–80 mm features: ±0.20%, with a lower limit of ±0.06 mm
• 81–150 mm features: ±0.30%, with a lower limit of ±0.15 mm

This makes Form 4 well suited to precision prototypes, mating components, manufacturing aids, presentation models, patterns, and functional parts where dimensional consistency matters.

Built for Reliable Production

Professional 3D printing needs to work repeatedly, not just produce an impressive first print.

Form 4 achieved a 98.7% print success rate in independent third-party testing, making reliability one of the core strengths of the platform.

Integrated monitoring and intelligent printer controls help detect and manage the printing process while reducing operator intervention.

Extensive Formlabs Resin Ecosystem

Form 4 supports a broad range of Formlabs professional SLA materials for applications ranging from visual models to functional engineering components.

Material categories include:

• General-purpose resins
• Tough and impact-resistant materials
• Rigid materials
• Flexible and elastic resins
• High-temperature materials
• Flame-retardant materials
• Silicone
• Ceramic
• Castable materials
• Specialty engineering resins

Third-party 405 nm photopolymer resins can also be used through Formlabs Open Material Mode.

This wide materials range allows one Form 4 platform to support prototyping, tooling, manufacturing, models, fixtures, casting patterns, and end-use applications.

Form 4 Basic Package Includes

The Formlabs Form 4 Basic Package includes:

• Formlabs Form 4 3D Printer
• Form 4 Resin Tank
• Form 4 Mixer
• Form 4 Build Platform
• Form 4 Finish Kit

Please Note

Resin is not included with the Basic Package.

Printed SLA parts also require washing and UV post-curing to achieve their final surface condition and mechanical properties.

For an integrated post-processing workflow, consider adding:

• Formlabs Form Wash
• Formlabs Form Cure
• Appropriate Formlabs Resin

For customers who require the printer, automated wash and cure equipment, and additional professional support together, the Form 4 Complete Package may be a better choice.

Automatic Resin Handling

Form 4 uses Formlabs' cartridge-based resin handling system to automatically maintain resin levels during printing.

The high-speed resin dispensing system helps prepare the printer quickly for each build and reduces the amount of manual resin handling required during day-to-day operation.

Integrated Camera and Remote Monitoring

Form 4 includes an integrated 5 MP camera with a resolution of 2592 × 1944 pixels.

When enabled, the camera can be used with Formlabs Dashboard for:

• Remote print monitoring
• Print history
• Print timelapses
• Workflow visibility

The camera can also be disabled, covered, or removed where required by workplace privacy or security policies.

PreForm Software

Prepare Form 4 jobs using Formlabs PreForm, Formlabs' print preparation software.

PreForm can assist with:

• Part orientation
• Automatic support generation
• Build-platform layout
• Slicing
• Material and print-setting selection
• Sending jobs to the printer

Together with Formlabs Dashboard, PreForm provides a streamlined workflow from CAD file to finished print.

Applications

Formlabs Form 4 is well suited to professional applications including:

Rapid Prototyping

Engineering

Create accurate functional prototypes using engineering materials with mechanical, thermal, flexible, rigid, or specialty properties.

Manufacturing Aids

Produce custom:

• Jigs
• Fixtures
• Alignment tools
• Assembly aids

Casting and Molding

Formlabs specialty materials can support workflows involving:

• Investment casting
• Silicone molding
• Rapid tooling
• Patterns
• Master models

Models and Presentation Parts
