StrongHeat resistantChemical resistantFunctional

Glass-filled nylon PA12 is standard PA12 mixed with glass beads, typically 30–40% by weight. The glass roughly doubles stiffness and improves dimensional stability and heat deflection (roughly 160–180 °C under light load, which is not a continuous-use rating). Tensile strength stays similar to standard PA12, but elongation drops from roughly 20% to under 10%, so it handles impact poorly and thin walls or fine features break more easily. Glass-filled nylon PA12 is a strong choice for rigid enclosures, housings, fixtures, and tooling.

Glass-Filled nylon with a raw granular surface finish.

Shot Peened

Shot Peened

Glass-Filled Nylon with a polished smooth surface finish.

Vapor Smoothed

Vapor Smoothed

17 colors

Vapor smoothing uses a vaporized solvent to partially melt and blend the outer layer of a 3D print, significantly reducing visible layer lines to create a more uniform, sealed finish.
