PLA and nylon are far apart. PLA is the easy, rigid filament for models. Nylon is the wear and heat specialist for gears and loaded parts. The right pick depends on what the part must do.

How they compare

The table maps the gap. PLA leads ease. Nylon leads wear, friction, and heat.

Green marks the category leader. PLA wins on ease. Nylon wins on wear and heat.

When to pick PLA

Pick PLA for display models, miniatures, and prototypes. It prints at 200 to 220 °C with no enclosure, per the Prusament PLA datasheet. It is the easiest filament to print.

When to pick nylon

Pick nylon for gears, sliders, and parts that face friction, load, or warmth. The Polymaker PolyMide CoPA datasheet rates its heat resistance to 180 °C. The cost is printing difficulty: nylon is highly hygroscopic and abrades brass nozzles.

Frequently asked

Is nylon stronger than PLA?
In wear and heat, yes. Nylon slides well and handles warmth. PLA is more rigid but brittle and heat sensitive.
Is nylon harder to print than PLA?
Yes. Nylon needs drying, an enclosure, and a hardened nozzle. PLA prints in open air.
Which is better for gears?
Nylon. Its low friction and wear resistance make it the standard for 3D-printed gears. PLA gears wear fast.
Does nylon handle more heat than PLA?
Yes. The Polymaker CoPA datasheet rates nylon heat resistance to 180 °C. PLA softens near 60 °C.
