Functional Resins
StrongDurableHigh detailFunctional

Tough resin is a photopolymer engineered to resist impact and mechanical stress better than standard general-purpose resin. Standard resin is stiff and detailed but brittle, prone to cracking under sudden force. Tough resin trades away some of that stiffness and tensile strength in exchange for noticeably higher elongation at break, which allows parts to flex somewhat before failing rather than shattering. The exact balance varies meaningfully between manufacturers, as some formulations prioritize a more moderate toughness gain while retaining more rigidity, and others push elongation and impact resistance much further at a greater cost to stiffness. Tough resin suits functional prototypes, snap-fit enclosures, brackets, clips, and mechanical assemblies that need to survive handling, impact, or repeated use without breaking.

Available finishes

Each finish can be combined with the available colors at checkout.

Standard

Standard

28 colors

Resin parts have a smooth surface with fine layer lines that are typically not very noticeable. The surface has a natural, semi-matte texture rather than a glossy shine, and marks from support removal can still be visible.

Glossy

Glossy

11 colors

This finish is painted to a glossy sheen in a color of your choice via Pantone matching, rather than the resin's natural material color. Very fine surface detail may be very slightly softened by the paint layer.

Matte

Matte

11 colors

The matte appearance is achieved with an opaque paint coating rather than the resin's natural material color. A wide range of colors can be chosen through Pantone matching. The result is a smooth, non-reflective, matte sheen.

Electroplated

Electroplated

4 colors

Electroplated parts are coated in a thin layer of real metal (typically nickel or copper), giving them a fully metallic, reflective look rather than a painted appearance. The metal layer also adds strength, conductivity, and abrasion resistance.

Electroplated Colored

Electroplated Colored

5 colors

This finish combines a real metal-plating layer with a custom color, giving parts a glossy, metallic sheen in color. The underlying metal layer also adds genuine strength and abrasion resistance beyond the resin alone.
