These are two of the most popular MJF nylon materials — but they’re built for very different jobs.

The other is built for precision and clean finishes.

So… what does your MJF part actually need?

🧱 Choose PA12-HP Nylon (MJF) if it must survive stress

• Mechanical brackets & mounts

• Functional enclosures

• Load-bearing prototypes

• Heat & chemical resistance

✨ Choose PA12S-HP Nylon (MJF) if details really matter

• Visible or customer-facing parts

• Snap-fit designs

• Complex geometries

• Smoother, cleaner surfaces
