$159.00

Grey Resin is a versatile material ideal for general-purpose prototyping, design models, and parts with fine details. Its matte surface finish, opaque appearance, and precision make prints ready to use directly off the printer. The neutral grey tone also provides an excellent base for painting or additional finishing.

Grey Resin V4.1, compatible with Form 3 Series printers, offers improved toughness compared to Grey Resin V4 (Legacy).

IMPORTANT: 5 L Container Requires a Resin Pump to work.

frequently asked questions

What is Grey Resin V4.1 used for?

It’s a general-purpose prototyping resin ideal for concept models, assemblies, and visual prototypes that require fine detail and smooth surface finishes.

Which printers are compatible with Grey Resin V4.1?

Grey Resin V4.1 is compatible with Form 3, Form 3+, Form 3B, Form 3B+, and Form 2 printers.

What makes Grey Resin V4.1 different from earlier Grey Resins?

V4.1 offers improved toughness, greater mechanical strength, and higher accuracy for detailed parts compared to earlier versions.

Does Grey Resin V4.1 require post-processing?

Yes. Printed parts should be washed in isopropyl alcohol (IPA) and then cured in the Form Cure to achieve full strength and surface quality.

Is Grey Resin V4.1 suitable for functional parts?

While durable, it’s primarily designed for visual and fit-check prototypes, not long-term mechanical or outdoor use. For functional parts, materials like Tough 2000 or Durable Resin are recommended.
