Heat resistantFunctionalStrongFlame retardant

Flame retardant polycarbonate (PC-FR) is standard polycarbonate formulated with flame-retardant additives to reliably achieve a UL94 V-0 rating – self-extinguishing within 10 seconds without flaming drips. This formulation can retain PC's core strength, impact resistance, and heat tolerance, although flame-retardant additives can generally reduce toughness in some polymer systems. PC-FR is well suited to electrical housings, connectors, and components near heat-generating equipment where both fire safety and mechanical performance matter.

The standard (as-printed) finish on FDM parts shows the natural texture of layer-by-layer printing. The visibility of the layer lines depends on part geometry and orientation, plus light marks where support material was removed.
