MJF – PA-12 40% Glass Beads (PA-12 GB)
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: 0.003″ (0.08 mm)
- Resolution: Minimum feature size of 0.020” (0.5mm)
- Heat Resistant up to 360F

Material Certifications
- UL94 HB Blue Card Certification for HP PA-12GB Material
- UL introduced the UL94 blue card, which indicates the type of processing equipment and settings required to claim compliance for each material. The old yellow card system is still valid for traditional processes such as injection molding and extrusion. But yellow card ratings do not apply to 3D printing. For instance, a filament made from UL94 yellow card certified pellets is not UL recognized.

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.
