Formlabs Resin V5: What Makes It Different and Why Use It with Form 4?

The Form 4 brought a major step forward in professional resin 3D printing, with faster printing, improved workflow, and a new generation of materials designed specifically around the Form 4 platform.

One of the key parts of that ecosystem is Formlabs Resin V5.

Formlabs developed its V5 general-purpose resins to take advantage of the Form 4 generation, combining fast print speeds, high dimensional accuracy, strong mechanical properties, and a professional surface finish.

But what actually makes Resin V5 different from previous Formlabs resins, and why should Form 4 users consider it?

Let's take a closer look.

What Is Formlabs Resin V5?

Formlabs Resin V5 refers to a new generation of resin formulations designed for the Form 4 Series.

Depending on the application and desired appearance, users can choose from different general-purpose V5 materials, including:

• Grey Resin V5

• Black Resin V5

• White Resin V5

• Clear Resin V5

These materials are designed to provide a balance of speed, accuracy, appearance, and mechanical performance, making them suitable for a wide range of professional 3D printing applications.

They are compatible with the Form 4, Form 4B, Form 4L, and Form 4BL platforms, depending on the specific resin.

What Makes Resin V5 Different?

The biggest difference is that V5 was developed to take advantage of the Form 4 ecosystem rather than simply being an older resin formulation carried forward to a new printer.

1. Faster Printing

One of the biggest advantages of the V5 generation is speed.

Formlabs states that several V5 general-purpose resins can print three times faster than their previous-generation counterparts when used with the Form 4 platform.

This can make a significant difference for businesses and professional users producing multiple prototypes or parts throughout the day.

Faster printing can mean:

• More prototypes in less time

• Shorter development cycles

• Higher printer utilization

• Faster design iterations

• Less waiting between projects

For teams using 3D printing as part of product development, saving time on each print can quickly add up.

2. High Dimensional Accuracy

Speed isn't useful if the finished parts don't meet the required dimensions.

Resin V5 is designed to provide high dimensional accuracy and fine feature reproduction, making it well suited for applications such as prototypes, models, manufacturing aids, and detailed parts.

This makes V5 a strong option when you need to evaluate:

• Part fit

• Form and function

• Fine details

• Enclosures

• Mechanical interfaces

• Prototype assemblies

The exact dimensional performance of a finished part will still depend on the model, orientation, print settings, post-processing, and application.

3. Stronger and More Versatile Parts

Another important benefit of the V5 generation is its combination of strength, stiffness, and toughness.

For example, Formlabs Grey Resin V5 has an ultimate tensile strength of 62 MPa, flexural strength of 103 MPa, and elongation at break of 13% when tested under Formlabs' specified conditions.

These properties make general-purpose V5 materials useful for more than purely visual models.

They can be used for:

• Functional prototypes

• Jigs and fixtures

• Product development

• Manufacturing aids

• Detailed models

• Form and fit testing

4. Professional-Looking Surface Finish

One reason Formlabs resins are popular for professional prototyping is their surface quality.

Grey, Black, and White Resin V5 are designed to produce clean, matte surfaces with crisp details. Formlabs describes these finishes as capable of rivaling the appearance of injection-molded parts.

This makes V5 particularly useful when the printed prototype will be shown to:

• Customers

• Designers

• Engineers

• Management teams

• Investors

• Product-development teams

Instead of looking like an early-stage prototype, a well-produced resin print can provide a much more polished representation of the final product.

5. Different V5 Materials for Different Needs

Another advantage of the Formlabs ecosystem is that you aren't limited to one general-purpose material.

Grey Resin V5

Grey Resin V5 is a versatile option for prototypes, models, manufacturing aids, and detailed parts. Its matte grey finish also makes small features easy to see.

Black Resin V5

Black Resin V5 provides a deep matte black appearance while maintaining the general-purpose characteristics of the V5 material family. It's a good option for models and prototypes where a dark, professional appearance is preferred.

White Resin V5

White Resin V5 offers a bright matte finish and is designed for applications including form-and-fit prototypes, anatomical models, presentation models, jigs, and fixtures.

Clear Resin V5

Clear Resin V5 is designed for transparent prototypes, models, enclosures, and other applications where visibility through the printed part is important. It can also be polished toward near-optical transparency.

Why Use Resin V5 with the Form 4?

The main reason is simple: Form 4 and Resin V5 were designed to work together.

The Form 4 platform uses a different printing architecture than previous Formlabs generations, and V5 materials are formulated to take advantage of that system.

This combination provides a workflow focused on:

Speed + Accuracy + Material Performance + Reliability

Instead of choosing a resin independently from the printer, Formlabs designed the Form 4 ecosystem around compatible materials, resin tanks, build platforms, and automated resin handling.

Form 4 Resin V5 vs Previous Resin Generations

So, what can users expect compared with older versions?

The exact improvements vary depending on the specific V5 resin, so it's important to check the technical data sheet for the material you're considering.

For example, Formlabs states that White Resin V5 has 2× the elongation at break and 25% higher impact strength than White Resin V4, while also printing three times faster on the Form 4 generation.

1 L or 5 L: Which Should You Choose?

Formlabs Resin V5 is available in both 1 L and 5 L options for compatible materials.

1 L Resin

The 1 L option is a practical choice for:

• Occasional printing

• Smaller teams

• Prototyping

• Trying a material for the first time

• Lower-volume production

The standard Form 4 resin cartridge system makes changing materials straightforward.

5 L Resin

If you're printing frequently, the 5 L option can be more convenient.

The Form 4 Resin Pumping System allows a 5 L resin container to feed resin directly to the printer, reducing the need for frequent cartridge changes. Formlabs states that the system can allow users to print five times longer between resin changes and reduce packaging waste by 86%.

For businesses running regular production or prototyping jobs, this can help reduce interruptions and simplify material management.

What Can You Make with Formlabs Resin V5?

Because of its balance of accuracy, speed, and mechanical performance, V5 general-purpose resins can be used across many workflows.

Rapid Prototyping

Create prototypes quickly and evaluate designs before moving to manufacturing.

Form and Fit Testing

Check whether components fit together as intended before committing to production tooling.

Product Development

Produce realistic prototypes for design reviews and development iterations.

Manufacturing Aids

Grey and other general-purpose V5 materials can be used for certain jigs, fixtures, and manufacturing aids.

Presentation Models

White, Black, Grey, and Clear options allow designers to select an appearance that suits the project.

Detailed Models

Resin printing is particularly useful when fine features and smooth surfaces are important.

Is Resin V5 Right for Every Application?

Not necessarily.

Resin V5 is an excellent general-purpose option, but Formlabs offers specialized materials for applications that require specific properties such as high temperature resistance, flexibility, high impact resistance, or extreme stiffness.

The best resin depends on what the finished part needs to do.

If you're primarily looking for a versatile resin for prototypes, models, and general-purpose professional printing, however, Resin V5 is a strong starting point.
