About Nylon PA12 Glass Bead

Parts made with Nylon PA 12 GB has the fine grain, high density and low porosity of Nylon 12, but with a greater stiffness and dimensional stability due to 40% glass bead incorporated into the plastic. PA 12 GB provides dimensional stability along with repeatability across prints and it is ideal for applications requiring high stiffness like enclosures, housing and tooling. Additionally, it’s less prone to warping during the printing process than Nylon PA12 so it is a great option for large or flat parts. 

Key Benefits

Certifications & Data Sheets

Available Surface Finishes

HP PA12 (raw finish).jpg
Raw (gray)

After the part has been printed it has a powdery gray look and feel. This finish is best suited for functional prototypes and non-visible parts.

Black Dye

Parts are submerged in a hot dye bath containing dye pigment. This gives a smooth, consistent finish with no loss of dimensional accuracy.

Cerakote Red on Airforce Velocity Nylon PA12 Snowmobile part 3D printed with HP Multi Jet

Cerakote is a thin-film ceramic coating applied to 3D printed parts to improve looks and functionality. A variety of colors are available.
