MJF – PA-12 40% Glass Beads (PA-12 GB)

Last updated: July 21, 2025

MJF – PA-12 40% Glass Beads is a 40% glass bead-filled thermoplastic material with excellent mechanical properties and dimensional stability. MJF – PA-12 GB is Ideal for applications requiring high stiffness, like enclosures, housings, fixtures and tooling and can be applied to the production of functional parts across a variety of industries.

Key Material Facts

  • Ideal for complex assemblies, housings, enclosures, and watertight applications.
    • Added glass content will make the parts stiffer and less flexible
    • Not recommended for parts that require snap features as these will be fragile.
  • A very strong thermoplastic that not only works well for prototypes but also end-use parts.
  • Parts are solid and are air / fluid tight right off the printer, no sealing required
  • Compatible with assembly features including:
  • Provides excellent chemical resistance to oils, greases, aliphatic hydrocarbons, and alkalies.
  • Material can be Vapor Smoothed
  • Layer thickness: 0.003โ€ณ (0.08 mm)
  • Resolution: Minimum feature size of 0.020โ€ (0.5mm)
  • Heat Resistant up to 360F

Finish / Color Options

RAW – Part is left gray after beadblasting, this is the color of the parts after they come off the printer. More examples of this finish can be seen here.

BLACK DYE – Part is dyed black after beadblasting, this is the standard finish for MJF PA-12 GB parts unless something else is requested by the customer. F3DP does not charge extra for this finish. More examples of this finish can be seen here.

CERAKOTE – This is a ceramic based paint that can be applied to MJF PA-12 GB Parts, for more information please check out this page.
