Formlabs Grey Resin V5 is a next-generation professional SLA/LFS 3D printing resin developed specifically for the Form 4 ecosystem. It combines ultra-fast print speeds, exceptional dimensional accuracy, strong mechanical performance, and a premium matte surface finish. Designed for engineering, industrial manufacturing, dental workflows, product development, and high-end prototyping, Grey Resin V5 delivers reliable and repeatable results for both visual and functional applications.

The V5 formulation represents a major advancement over Grey Resin V4. Optimized for the powerful Form 4 Low Force Display™ printing engine, this material enables significantly faster print production while simultaneously improving detail reproduction, impact resistance, and surface consistency. The result is a resin that supports rapid iteration, professional presentation quality, and production-level reliability.

Key Features

Exceptional Print Quality

Grey Resin V5 produces highly detailed parts with a smooth matte gray finish that closely resembles injection-molded components. Fine textures, sharp edges, embossed text, intricate geometries, and delicate features are reproduced with outstanding precision.

The neutral gray color makes the material particularly suitable for:

• Product design validation
• Client presentations
• Engineering demonstrations
• Surface inspection
• Visual prototypes
• Architectural models
• Dental and medical models

The matte finish also minimizes visible layer lines, providing a clean and professional appearance directly after printing.

High Dimensional Accuracy

Grey Resin V5 is engineered for applications requiring tight tolerances and repeatable precision. Formlabs specifies XY dimensional tolerances of approximately ±0.15% with a lower limit of ±0.02 mm, making it suitable for demanding industrial and technical workflows.

Typical precision applications include:

• Functional prototypes
• Assembly verification
• Jigs and fixtures
• Fit and form testing
• Manufacturing aids
• Enclosures and housings
• Precision concept models

Its excellent dimensional stability ensures consistency across multiple print runs and production batches.

Mechanical Performance

Grey Resin V5 offers a balanced combination of rigidity, strength, and moderate flexibility, enabling printed parts to withstand everyday handling and functional testing.

(After post-curing at 60°C for 15 minutes)

• Tensile Strength: 62 MPa
• Tensile Modulus: 2675 MPa
• Elongation at Break: 13%
• Flexural Strength: 103 MPa
• Flexural Modulus: 2750 MPa
• Izod Impact Strength: 32 J/m
• Heat Deflection Temperature (0.45 MPa): 71°C

These properties make Grey Resin V5 ideal for:

• Functional engineering prototypes
• Durable concept models
• Technical demonstration parts
• Industrial tooling aids
• Short-run end-use components
• Production validation
• Ergonomic testing

Ultra-Fast Printing Performance

One of the most important improvements of Grey Resin V5 is its extremely high print speed on the Form 4 platform. Compared to previous generations, users can achieve print times up to three times faster while maintaining exceptional surface quality and accuracy.

This increased productivity allows businesses to:

• Accelerate product development cycles
• Reduce prototyping lead times
• Improve machine throughput
• Increase production efficiency
• Lower operational costs per part
• Enable faster customer approvals

For industrial environments and service providers, this translates directly into higher productivity and improved workflow efficiency.

Improved User Experience

Low Odor Formulation

Grey Resin V5 features a low-odor chemistry with reduced volatile organic compound (VOC) emissions during printing. This creates a more comfortable working environment in offices, studios, labs, and production facilities.

Simplified Post-Processing

The material is designed for fast and efficient post-processing workflows:

• Washing time: approximately 5 minutes
• Optional post-curing:
  • 5 minutes at room temperature
  • or 15 minutes at 60°C

This streamlined workflow allows operators to move rapidly from printing to finished parts with minimal downtime.

Surface Finish and Aesthetics

Grey Resin V5 is especially appreciated for its premium visual appearance. The neutral matte gray color highlights details clearly while reducing reflections and surface glare.

Benefits include:

• Excellent photography and presentation quality
• Easy sanding and painting
• Smooth priming and coating
• Professional visual appearance
• Ideal base material for finishing operations

Because of its clean surface quality, Grey Resin V5 is frequently used for customer-facing prototypes and presentation models.
