Print real colour prototypes — without painting, dyeing, or finishing

Color Base Resin is the foundation material for Formlabs Color Kit. Mix it with any Color Kit pigment recipe to produce matte, opaque “Color Resin” blends — with consistent colour throughout the entire part, not just on the surface.

Ideal for looks-like prototypes, concept models, and props where visual impact matters — get presentation-ready parts straight off the printer while keeping the workflow simple and repeatable.

Why Choose Formlabs Color Base Resin?

A Perfect Foundation

Pair Color Base Resin with Color Kit pigments to produce repeatable colours that stay consistent through the entire part — great for sanded edges and fine features.

Minimize Waste

Use every drop of pigment by replenishing the base resin as needed — ideal for teams printing colour prototypes regularly.

Smooth, “Finished” Surface

Create solid, matte parts that look production-ready right out of the printer — without painting or dyeing.

Flexible Colour System

Start with Formlabs’ proven recipes, then dial in custom brand colours by adjusting pigment mixes to suit your project.

Applications

Color Base Resin paired with Color Kit pigments is ideal for field testing aesthetic prototypes and concept models where colour communicates design intent instantly.

Consider Color Base Resin for:

  • Looks-like prototypes with a matte finish
  • Concept models for design reviews and stakeholder approvals
  • Props & figurines with bold, consistent colour
  • Display parts where painting would slow you down

Finish: Solid colour parts with a matte, opaque appearance (when mixed with pigments).

Tip: If you need a very specific colour target, start from the closest recipe, print a small swatch, then fine-tune the pigment mix.

Workflow Overview

Color Base Resin is part of a straightforward mix + print + wash workflow. For best surface finish and strength, a short post-cure is optional but recommended.

  • Mix pigments into Color Base Resin using the manufacturer’s colour recipes for consistent results.
  • Print using the recommended preset for your compatible Form 4 workflow.
  • Wash to remove excess resin on the surface via an alcohol (or ether) wash.
  • Post-cure (optional) — recommended to reduce surface tack and improve mechanical properties.
